The desktop app is Windows only and adds the features that need deeper integration: Navigation and Back/Lay surebets. (https://www.oddstorm.com/help/faq#q-platforms) - **What is the difference between Pro and Elite?** The only difference is the Navigation feature: in the desktop app it opens the bookmaker at the right event for you, on the bookmakers it supports (ask support about yours). Scanning speed, odds and timing are identical on both tiers. (https://www.oddstorm.com/help/faq#q-proelite) - **What plans are available?** A plan is a tier (Pro or Elite), a product (PreMatch, InPlay, or PreMatch+InPlay) and a duration (1, 6 or 12 months). Pro also comes as a 1-week plan: after 7 days it continues as the monthly plan unless you cancel auto-renew before then, and the money-back guarantee doesn't cover it. There are no 3-month plans.

Betting with regulated bookmakers is legal, and no law forbids covering all outcomes of an event across different bookmakers. Bookmakers dislike arbitrage and may limit very obvious arbers, but that is a business decision under their terms, not a legal issue. Gambling itself must be legal where you live, so check your local rules first.

Sports arbitrage (a surebet, or arb) is betting on every possible outcome of one match at different bookmakers whose odds disagree, so that you lock in a profit whichever side wins. It is not gambling on a result: it is trading a pricing disagreement between bookmakers. Bookmakers set their own odds, and they do not always agree. When two bookmakers price the same match differently enough, the combined odds can guarantee more money back than you stake, no matter what happens on the pitch. That gap is the arbitrage. Arbers (people who bet arbitrage) do this systematically: find the gap, split the stake correctly between the outcomes, place both bets fast, repeat. Each arb pays a small percentage, and the profit comes from volume. #### How a surebet works Every set of odds implies a probability: the bookmaker's estimate plus their margin. When you back ALL outcomes of a match, you normally lose the margin. But if you pick each outcome at the bookmaker offering the HIGHEST odds for it, the combined implied probability can drop below 100 percent. The further it drops below 100, the bigger your guaranteed profit. The stake split does the locking. You divide your total stake across the outcomes in inverse proportion to the odds, so every outcome returns the same amount. The match result stops mattering. > **Note:** Example: a two-way market where bookmaker A gives odds 2.10 on over 2.5 goals and bookmaker B gives 2.10 on under 2.5 goals. Combined implied probability: 1/2.10 + 1/2.10 = 95.2 percent, below 100, so the pair is an arb. With EUR 1,000 you stake EUR 500 on each side. Whichever side wins pays 500 x 2.10 = EUR 1,050: EUR 50 profit, 5 percent on your stake, whatever the score. Real arbs are usually smaller, typically 1 to 3 percent per bet. That sounds modest until you remember you can place many of them every day and none of them can lose. #### Why do surebets exist at all? Because bookmakers are not one market. Each book prices matches with its own models, its own traders and its own customers pushing the line around. Disagreements appear constantly: - News reacts at different speeds: an injury or lineup change moves one bookmaker's odds seconds or minutes before another's. - Different customer bases: a bookmaker heavy with fans of one team shades its odds to balance its own book, not the global market. - Plain mistakes: a trader types the wrong number or a model misfires. These create the biggest gaps, and also the riskiest ones. InPlay multiplies all of this. During a live match odds move every second, so live arbitrage produces more and larger surebets than PreMatch, at the price of needing to act much faster. #### The main kinds of arbitrage The mechanics are always the same (cover all outcomes, split the stake), but arbers work several shapes of opportunity: - Classic surebets: two-way or three-way markets across two or three bookmakers. The bread and butter. - Middles: the two bets leave a gap where BOTH can win (for example over 2.5 at one book, under 3.5 at another; three goals wins both). You pay a small guaranteed cost for a shot at a big double win. - Polish middles: the reverse, built from cross-market combinations that pay a small profit on almost every result and take a known, limited loss when the result lands in one narrow gap. An OddStorm specialty. - Back/Lay arbitrage: back an outcome at a bookmaker and lay the same outcome at a betting exchange like Betfair. Gentler on bookmaker accounts, limited by exchange liquidity and commission. #### The real risks (arbitrage is not risk-free work) The bet, once both legs are placed at the right odds, cannot lose. The process around it can. The four risks that actually cost arbers money: - One leg moves before you place the other. You are left holding a normal bet. The fix is speed and placing the fast-moving leg first. - A bet gets voided as a palpable error. Suspiciously high arbs (10 percent and up) are usually a bookmaker mistake, and their terms let them cancel it. The other leg stays open. - Your own mistakes: wrong stake, wrong market, wrong period (first half instead of full time). Rule differences between bookmakers count here too. - Account limitations: bookmakers can and do restrict accounts that only ever bet arbitrage. Managing this is a craft of its own. > **Tip:** Rule of thumb: treat every arb above 10 percent as a probable error and skip it. The steady money lives between 1 and 5 percent. #### Where scanners come in Finding disagreements between dozens of bookmakers by hand is impossible: odds change every second across thousands of matches. Arbitrage software scans the bookmakers continuously, computes the implied probabilities across every combination, and hands you the opportunity with the stakes already split. OddStorm has done exactly that since 2007, with a focus on speed: InPlay surebets are delivered within 1 to 3 seconds, and PreMatch odds are scanned every 15 to 180 seconds depending on the bookmaker (the sharp ones most often), across 30 bookmakers, with middles and Polish middles included. The software finds and calculates; placing the bets stays in your hands, always. #### Where to go next Start with how much bankroll the numbers actually need, check whether arbitrage is legal where you live, and then walk our step-by-step action plan from first bookmaker account to first settled arb. ### [How much money do I need?](https://www.oddstorm.com/guides/how-much-money-do-i-need) Updated 2026-10-18. You can learn arbitrage with a few hundred euro, but the arithmetic starts paying for the time you spend from roughly EUR 1,000 to 2,000 spread across your bookmakers. This guide walks the actual math so you can pick your own number. Arbitrage profit is a percentage of turnover: every arb locks in a small percentage of what you stake. That single fact drives everything about bankroll: the same work, the same arbs, the same hours produce ten times more money with ten times the bankroll. #### The practical floor A typical arb pays 1 to 3 percent. If your whole bankroll is EUR 200, a good day of arbing might lock in a few euro: real, but not worth the hours for most people. From about EUR 1,000 the same day starts producing meaningful money, and at EUR 2,000+ arbing begins to look like a paid part-time activity. There is also a mechanical floor: bookmakers have minimum stakes, and your money is SPLIT across several bookmaker accounts. With too little in each account you will constantly find arbs you cannot actually place because one leg's account is empty. > **Note:** Start with what you can afford to have locked up for weeks. Money in bookmaker accounts is not gone, but it is slow: deposits are instant, withdrawals take days, and moving money too often attracts attention. #### How to split it across bookmakers Do not divide equally. Money should sit where the arbs are: - Sharp anchors (Pinnacle, exchanges like Betfair): 30 to 40 percent. They appear in a large share of all arbs, they accept winners, and they never limit you. - The big soft bookmakers available in your country: most of the rest, split across 5 to 10 books. - A reserve outside the bookmakers (in your e-wallet or bank): 10 to 20 percent, ready to top up whichever account runs dry. Rebalance weekly, not per bet. When one account grows fat (it keeps winning) and another runs empty, move money through your e-wallet in one calm, round-number transfer. #### Why turnover, not luck, decides your result Each arb returns your stake plus 1 to 3 percent within hours or days (when the match settles). The faster the money comes back, the faster you can place the next arb with it. Your monthly result is roughly: average arb percentage x how many times you turn the bankroll over. InPlay arbs settle the same day, so InPlay-focused arbers turn their bankroll many times per week. PreMatch money can sit locked until the weekend fixtures play out. This is why serious arbers track turnover, not win rate: the win rate is 100 percent by construction. > **Tip:** A EUR 2,000 bankroll turned over twice a week at an average 2 percent locks in around EUR 80 per week. Scale the numbers to your own bankroll and pace: the formula stays the same. #### Starting smaller anyway A small start is fine if your goal is learning, not income: - Open two or three bookmakers and an OddStorm account, and paper trade first: pick arbs, write down the stakes, watch them settle. Paper trading needs the event names, which the free view hides and a plan or the 24-hour trial shows. - When you go live, treat the first EUR 200 to 500 as tuition. Speed, stake rounding and bookmaker quirks are learned by doing. - Only scale the bankroll once you have placed 30 to 50 arbs without process mistakes (wrong market, missed leg, panic). #### Where to go next Next questions in order: how many bookmaker accounts you actually need, and what profit to realistically expect once the money is in place. ### [How many bookmaker accounts do I need?](https://www.oddstorm.com/guides/how-many-bookmakers) Updated 2026-07-02. Around ten is the practical starting point: enough that arbs regularly appear between books you actually hold, few enough to manage deposits, verification and balances without drowning. Here is how to pick them and in what order. An arbitrage needs both of its legs to be at YOUR bookmakers. With three accounts you will watch most opportunities pass by because one side sits at a book you do not have. Every account you add multiplies the combinations, and the effect compounds fast in the beginning. #### Why ten, not three and not thirty The curve flattens. Going from 3 to 10 accounts multiplies your reachable arbs many times over; going from 20 to 30 adds little, because the extra books are smaller, slower and rarely on the best side of a price. Meanwhile every account is real overhead: KYC documents, deposits parked, terms to remember, withdrawal rules. Ten well-chosen books cover the bulk of what a scanner like OddStorm will show you day to day. Grow past that only when your bankroll and routine are ready for it. #### Which ones to open first Order matters more than the exact list: - Sharp anchors first: Pinnacle plus a betting exchange (Betfair). They sit on one side of a huge share of arbs, they take large stakes, and they do not limit winners. - Then the biggest soft bookmakers licensed in your country: the household names with big turnover. Big books move slower and produce the pricing disagreements you feed on. - Then one or two regional specialists your market favors. Local books often lag international odds, which is exactly what an arber wants. Check each candidate against our live supported list first: a bookmaker OddStorm does not scan cannot bring you scanner arbs, however good it is otherwise. > **Note:** Licensing differs per country and changes often. Before opening anything, confirm the bookmaker is licensed to operate where you live; that is on you, not on any list. #### Get verification out of the way on day one Every bookmaker will eventually demand identity documents (KYC), usually exactly when you try to withdraw. Do not let that surprise you mid-arb: - Upload your documents immediately after registering, before the first deposit if the book allows it. - Use identical personal details everywhere: name as in your ID, one address, your own payment methods. Mismatches freeze accounts. - Do a small test deposit AND withdrawal early. A book that pays you EUR 20 smoothly will pay EUR 2,000. > **Tip:** Keep a simple sheet per bookmaker: login, deposit method, minimum stake, withdrawal time from the test run. Ten accounts feel like two when the boring facts are written down. #### When to grow the list Add accounts when you keep seeing good arbs die because one leg is at a book you lack, and your existing accounts are verified, funded and routine. That is a signal of lost profit, and it names the exact bookmaker to open next: the one that keeps appearing on the missed side. #### Where to go next With accounts in place, the next questions are how much money to spread across them and how to behave so the soft books keep you around. ### [How much can you realistically earn?](https://www.oddstorm.com/guides/realistic-profit) Updated 2026-10-18. Active arbers commonly target 10 to 20 percent of their bankroll per month. Not per bet, not guaranteed, and not passive: the number comes from placing many small arbs and turning the bankroll over again and again. Here is the honest math. Arbitrage is the rare betting activity where the profit per bet is locked in advance, so expectations should be MORE precise than in gambling, not less. If a number sounds exciting, check it against the arithmetic below. #### The arithmetic Your monthly result is approximately: average arb percentage x number of arbs x average stake. Or equivalently: average arb percentage x bankroll x how many times you turn your bankroll over in a month. Typical inputs for an active arber: arbs in the 1 to 3 percent range (average around 2), a bankroll that turns over once or twice a week depending on how fast your bets settle. Two turnovers a week at 2 percent is roughly 16 percent on the bankroll in a month. > **Note:** Worked example: EUR 2,000 bankroll, average arb 2 percent, bankroll turned over 8 times in the month. 2,000 x 0.02 x 8 = EUR 320, or 16 percent. Double the bankroll or the pace and the euro amount doubles with it. #### What actually moves the number Four levers, in order of impact: - Bankroll size: profit scales linearly with it. This is the biggest lever and the least glamorous one. - Time and speed: more hours at the screen means more arbs caught before they vanish. InPlay especially rewards presence and fast hands. - Settlement speed: InPlay arbs free your money the same day, PreMatch can lock it until the weekend. Faster settlement = more turnovers. - Bookmaker health: limited accounts and empty balances silently cut the arbs you can actually take. Account care compounds. #### The honest caveats Months are not equal. Big tournament weeks produce more arbs; summer breaks produce fewer. Early months run below target while you learn, get verified everywhere and make the beginner mistakes everyone makes. The percentage also does not scale forever. Very large bankrolls hit bookmaker stake limits and account restrictions, which is why professional arbers plateau and diversify (exchanges, Back/Lay, more books) rather than compound indefinitely. > **Warning:** Ignore anyone promising fixed monthly income, 'passive' arbitrage returns, or results without hours at the screen. The math above is the whole story: percentage x turnover. Everything else is marketing. #### What it costs in time Treat arbing as paid work, not passive income. A realistic starter rhythm is 1 to 3 focused hours per day: scanning, placing, topping up accounts, logging results. The scanner compresses the finding part to seconds; the placing and the money logistics remain yours. #### Where to go next If the numbers work for you, size your bankroll properly and then learn the mistakes that cost beginners their first month, so you can skip them. ### [Is arbitrage betting legal?](https://www.oddstorm.com/guides/is-arbitrage-betting-legal) Updated 2026-07-02. Yes. Arbitrage betting is placing ordinary bets at odds the bookmakers themselves published. No law anywhere forbids betting on all outcomes of a match at different bookmakers. The friction arbers meet is commercial (bookmaker terms and account limits), not legal. The question deserves a precise answer because two different things get mixed up: what the LAW says about betting, and what BOOKMAKERS think about customers who only take good prices. They are not the same thing. #### What the law actually covers Gambling laws regulate whether betting itself is allowed where you live, at which operators, and from what age. If placing a normal bet with a licensed bookmaker is legal in your country, placing five of them at five bookmakers is exactly as legal, regardless of the fact that together they cover every outcome. There is no offence called arbitrage. You are not deceiving anyone: you bet real money at prices the bookmaker chose to display, and you can lose a leg like any customer (the profit comes from the combination, not from any leg being safe). Courts and regulators have never treated taking a published price as fraud. #### What bookmakers can (and do) do about it Bookmakers are private businesses and their terms let them manage customers they find unprofitable. A book that decides you only ever hit their pricing mistakes can lower your stake limits, restrict promotions, or close the account going forward. That is a commercial decision inside their terms, not a legal accusation. This is the real-world constraint on arbers, and it is manageable: sharp bookmakers and exchanges (Pinnacle, Betfair) explicitly welcome winning customers, and behaving like a recreational bettor keeps soft books comfortable far longer. > **Note:** Voided bets are also terms, not law: when a bookmaker cancels an obviously wrong price (a palpable error), they are using a clause you accepted at signup. It is why suspiciously high arbs are risky, and it is entirely separate from legality. #### What to check for your own country Three things, all about betting in general rather than arbitrage: - Is online betting legal and regulated where you live, and which bookmakers hold a local license? Bet only where the bookmaker may lawfully take your bet. - Taxes: some countries tax winnings, many do not, a few tax stakes or turnover. Ask a local accountant; we cannot give tax advice. - Payment rules: a few jurisdictions restrict gambling transactions on cards or e-wallets, which affects how you move your bankroll. > **Warning:** One line we hold firmly: play by the rules you agreed to. Multi-accounting, betting through other people's names or misrepresenting your identity to a bookmaker breaks their terms and in some places the law. Arbitrage does not need any of it. #### Where to go next With the legal question settled, the practical ones are how much money to start with and how to run your accounts so they last. ### [The beginner mistakes that actually cost money](https://www.oddstorm.com/guides/beginner-mistakes) Updated 2026-10-20. Arbitrage cannot lose once both legs are placed correctly, so every beginner loss is a process mistake. The good news: the list of process mistakes is short, known, and completely avoidable. Here it is, with the fix for each. We answer support mail from new arbers every day, and the same handful of stories repeat. None of them are bad luck. Read this once and you skip the expensive month most people pay first. #### Chasing arbs that are too good A 15 percent arb feels like a jackpot and is almost always a bookmaker error. Bookmaker terms allow voiding palpable errors, so the wrong leg disappears and you are left with a live one-sided bet you never wanted. The bigger the percentage, the higher the chance one leg is a mistake. > **Warning:** Treat anything above roughly 10 percent as a trap until proven otherwise. The steady money lives between 1 and 5 percent. Boring is the business model. #### Placing one leg and hesitating on the other The arb exists only while both prices exist. Beginners place the easy leg, then re-check the numbers, then go look for a better second price... and the odds move. Now they own a normal gamble. The fix is a fixed order: place the leg most likely to move FIRST (the sharp book or the exchange, or the InPlay leg), then complete the second leg immediately, without renegotiating with yourself. If the second price is gone, take the best remaining price and exit small; do not wait for a miracle. #### Stakes that scream arbitrage The calculator says bet EUR 173.42. A recreational customer never bets EUR 173.42. Odd stakes on odd markets are the fastest way to get a soft bookmaker's attention and a limited account. > **Tip:** Round every stake to natural amounts (20, 50, 100, 150) and accept that the lock is a few cents less perfect. An account that lives for years beats a perfect split this afternoon. #### Ignoring rule differences between bookmakers Both legs must cover the SAME thing. Classic traps: - Periods: one bet on full time, the other accidentally on first half or 'to qualify' instead of 90 minutes. - Extra time and penalties: knockout football markets differ per bookmaker on what counts. - Voids and pushes: Asian handicap whole and quarter lines can refund all or half of a stake, European handicaps never refund; a push on one leg is not a push on the other. #### Sloppy money logistics Not a betting mistake, but it kills more beginners than any odds movement: - An arb appears and the account on one side is empty. Keep a reserve in your e-wallet and top up the moment a balance runs low. - Withdrawing constantly, in odd amounts. Withdraw rarely, in round numbers, after wins AND after losses look normal. - No records. Log every arb (date, books, stakes, result). Memory lies; the sheet does not. #### Skipping paper trading The cheapest lesson in arbitrage is the one you do not pay for. Before real money: pick live arbs from the scanner, write down the stakes you would place, then watch both legs settle. Do this for 20 to 30 arbs. Paper trading needs the event names, which the free view hides and a plan or the 24-hour trial shows. You will make every beginner mistake on paper (miss a leg, misread a market, watch odds vanish mid-placement) and each one costs nothing. When three days pass without a process error, you are ready for small real stakes. #### Where to go next Ready to do it properly from day one? Walk our step-by-step action plan: it sequences accounts, money and first bets so the mistakes above never get their chance. ### [The arbitrage action plan](https://www.oddstorm.com/guides/arbitrage-action-plan) Updated 2026-10-18. From zero to your first settled arb in eight steps and about two weeks. Nothing here is theory: this is the exact sequence we would follow ourselves starting today, with the waiting built in where reality puts it (verification, deposits, learning). Most guides explain WHAT arbitrage is. This one is the checklist for DOING it. Each step names its exit condition, so you always know whether you are ready to move on. Read What is sports arbitrage first if any term below is new; this plan assumes the concepts and gets straight to execution. #### Step 1: Decide your bankroll and park it in an e-wallet Pick the amount you can leave locked up for weeks (EUR 1,000 to 2,000 makes the hours worthwhile; less is fine for learning). Open an e-wallet bookmakers in your market support (Skrill and Neteller are the arber standards) and put the money there. The e-wallet becomes your hub: deposits to books are instant, and rebalancing between books goes through it. Exit condition: money sits in the wallet, verified and ready. #### Step 2: Open the anchor accounts Register at the books that will sit on one side of most of your arbs: - Pinnacle: the sharp anchor, welcomes winners, high limits. - A betting exchange (Betfair): lets you lay outcomes and is the backbone of Back/Lay arbing later. - The two or three biggest soft bookmakers licensed in your country. #### Step 3: Verify everything NOW, not at withdrawal time Upload identity documents at every bookmaker immediately, with identical personal details everywhere. Then do a small deposit AND a small withdrawal at each: you want the payment pipes proven while nothing is at stake. This step runs in the background over several days; start it early precisely because it is slow. > **Note:** Exit condition for steps 2 and 3 together: five to eight accounts, all verified, each holding a starter balance, each having completed one test withdrawal. #### Step 4: Create your free OddStorm account Register at OddStorm (free, no card). The free view caps profits at 0.50 percent and hides the event names: enough to watch the real rhythm of arbs appearing and dying, but not to trade one on paper, because you can't find a match you can't name. For the next step you need the names, which a plan or the 24-hour trial shows. #### Step 5: Paper trade 20 to 30 arbs For each arb you would take: write the stakes down, find both markets at both bookmakers by hand, note whether the prices were still there, then track the settlement. No money moves. You are training the eyes and hands: finding the market fast, reading periods correctly, feeling how long a price survives. > **Tip:** Three consecutive days without a process mistake (wrong market, wrong period, imaginary price) is your green light. Most people need about a week. #### Step 6: Go live small, PreMatch first Activate a subscription (or use the 24-hour trial: available Monday to Thursday, one per user, asked from support at least 24 hours ahead from your registered email) and place your first real arbs with these rules: - PreMatch only for the first week: more time per decision, calmer pace. - Stakes at half of what the bankroll allows, rounded to natural amounts (20, 50, 100). - Only arbs between 1 and 5 percent. Skip everything above 10 percent: those are usually errors. - Place the fast-moving leg first (sharp book or exchange), complete the second leg immediately. #### Step 7: Log every arb and review weekly A simple sheet: date, match, market, books, stakes, arb percentage, settled result, mistakes made. The log is your profit calculator (percentage x turnover, measured instead of guessed) and your early-warning system: patterns of near-misses show up in writing long before they show up in the balance. #### Step 8: Scale deliberately After two or three clean weeks: raise stakes toward the calculator's numbers, add InPlay sessions (they pay best and demand the most), open the next bookmakers where arbs keep escaping you, and rebalance accounts weekly through the e-wallet. > **Warning:** Scale ONE variable at a time: stakes, or pace, or new books. Scaling everything at once is how tidy systems turn into expensive chaos. #### That is the whole plan Two weeks, eight steps, no theory left on the table. Everything deeper (middles, Polish middles, Back/Lay, account longevity) has its own guide in this section, and the scanner is waiting whenever you are. ## Guides: Concepts ### [Two-way and three-way surebets](https://www.oddstorm.com/guides/two-way-and-three-way-surebets) Updated 2026-10-18. A two-way surebet covers a match with two bets whose outcomes cannot both lose (Over vs Under, home win vs 'draw or away'). A three-way surebet covers the classic 1X2 market with three bets, one per outcome, usually at three different bookmakers. These two shapes are the bread and butter of arbitrage. Every arbitrage, however exotic, reduces to the same rule: the legs together must cover every possible result of the match. The number of legs is just a consequence of which markets you combine. #### Two-way surebets (2 legs) The simplest and safest shape: two bets, two bookmakers, no result left uncovered. Classic pairs are Over vs Under on the same goal line, a home win (1) against 'draw or away win' (X2), or an Asian handicap against its mirror. Two legs mean two chances to make a placement mistake instead of three, which is why beginners should live here first. > **Note:** Example: Liverpool to win (1) at 2.30 with bookmaker A, stake EUR 100. Real Madrid or draw (X2) at 1.85 with bookmaker B, stake EUR 124.32. If Liverpool win: 230 - 224.32 = EUR 5.68 profit. Any other result: 229.99 - 224.32 = EUR 5.67. The result never matters. Note how the stakes are unequal: each stake is inversely proportional to its odds so both returns land on the same number. The calculator does this for you; your job is only to place both legs fast and on the RIGHT markets. #### Three-way surebets (3 legs) Football's main market has three outcomes (1, X, 2), and sometimes the best prices for each sit at three different bookmakers whose combined implied probability drops below 100 percent. You place three bets and every result returns the same amount. > **Note:** Example: Liverpool (1) at 1.50 for EUR 100 at bookmaker A, the draw (X) at 6.00 for EUR 25 at bookmaker B, Real Madrid (2) at 8.10 for EUR 18.52 at bookmaker C. Every outcome returns about EUR 150 against EUR 143.52 staked: EUR 6.48 locked in. Three legs cost more time and one more account with money in it, and the middle leg (the draw) often sits at a smaller bookmaker. The percentages compensate: three-way disagreements survive longer because fewer people can cover all three sides quickly. #### Cross-market combinations Legs do not have to come from the same market. Scanners like OddStorm combine markets that jointly cover everything: - A goal line against a different goal line (Over 2.5 vs Under 3.0), which can also create middles. - An Asian handicap against a European handicap or a 1X2 leg (AH1 -1.5 vs EH2 +2.0). - Draw-no-bet or AH 0 against the opposite double chance (DNB home against X2): on a draw the DNB stake comes back and X2 wins. > **Tip:** Cross-market arbs are where the biggest and longest-lived opportunities hide, because checking them by hand is hopeless: OddStorm computes thousands of combinations per match continuously. #### Which shape should you take? Take the percentage, not the shape, but respect your own speed: two-way arbs need two clean placements, three-way arbs need three. Until placing a leg takes you seconds, prefer two-way arbs and PreMatch pace. The profit difference between shapes is noise compared to the cost of one botched leg. #### Where to go next Two market families power most cross-market arbs and both have their own guide: Asian handicaps, and the middles that goal-line gaps create. ### [Middles: the arbs where both bets can win](https://www.oddstorm.com/guides/middles) Updated 2026-10-20. A middle is built like a surebet, but the two legs leave a gap between them: results inside the gap win BOTH bets at once. You pay a small guaranteed cost (or lock a small profit) for a shot at a double win. It sits between arbitrage and value betting, with the risk precisely measurable. Middles are less famous than surebets and unfairly so: priced right, they are one of the highest expected-value plays in sports betting, because you risk cents to win the whole gap when the score cooperates. #### How a middle works Take two lines that overlap: Over 2.5 goals at one bookmaker and Under 3.5 at another. Two goals or fewer: Under wins. Four or more: Over wins. Exactly three goals: BOTH win. The overlap (here: exactly 3 goals) is the middle. Handicap middles work the same way with margins of victory: AH1 +0.75 against the away win leaves 'away wins by exactly one' as the winning zone, where the away leg pays and the quarter line hands back half the AH stake. > **Note:** Worked example (real OddStorm case): AH1 +0.75 at 1.19 at bookmaker A for EUR 100, and the away win (2) at 4.70 at bookmaker B for EUR 25.31. Home wins or draws: you lose EUR 6.31 total. Away wins by two or more: you lose EUR 6.35. But away wins by EXACTLY ONE goal: the away leg pays, half the AH stake comes back, and you win EUR 43.65. You risk about 6.31 to win 43.65. #### The middle value: risk, measured OddStorm shows every middle with its VALUE: what you win when the gap hits divided by what you lose when it misses, plus one. The example above is (43.65 / 6.31) + 1 = 7.92: lose EUR 6.31 six times, hit once, and you are still ahead. The value turns middles from gambling into portfolio math. You do not need to predict THIS match; you need the gap to hit often enough across many middles, and one-goal margins and common goal totals hit far more often than the priced-in frequency on well-chosen middles. > **Tip:** Higher value = lower risk per hit needed. Set a personal floor (for example, only middles with value above 6 on one-goal gaps) and take every one that passes: consistency does the compounding. #### MAX middles: the free shots Some middles price so well that even the MISS is profitable: the two legs alone form a small surebet, and the gap only decides whether you win small or win big. OddStorm marks these as MAX middles. There is no scenario where you lose; take every single one you can place. #### When middles beat plain surebets Middles are a deliberate style choice on top of your arbitrage base: - Your bankroll can breathe: misses cost small, known amounts, and the wins arrive in lumps. Size stakes so a normal miss streak does not bend your discipline. - You want gentler bookmaker optics: middle bets look like ordinary Over/Under and handicap bets, not like error-sniping, and the stakes rarely need ugly decimals. - Football's score distribution is your friend: one-goal margins and 2-3 goal totals are the most common results, exactly where good middles live. #### Where to go next The mirror image of the middle, betting AGAINST the gap, is the Polish middle: an OddStorm specialty with its own guide. ### [Polish middles: betting against the gap](https://www.oddstorm.com/guides/polish-middles) Updated 2026-10-20. A Polish middle is a middle turned inside out: the two legs pay a locked profit on EVERY result except one narrow gap, where you take a known, limited loss. You win small often and lose small rarely, and the ratio between the two is printed on every opportunity. Polish middles are an OddStorm specialty: our scanner builds them from cross-market combinations most tools never check. They suit arbers who like frequent small wins and can hold discipline through the occasional gap hit. #### How a Polish middle works Combine two overlapping lines so that their wins cover everything EXCEPT a single result band. On most outcomes the winning leg covers the other and the pair pays like a normal surebet; when the result lands exactly in the gap, one leg loses more than the other wins. Compare with a regular middle: there you PAY a small cost hoping the gap hits. In a Polish middle you COLLECT a small profit hoping the gap misses. Same geometry, opposite side of the trade. > **Note:** Worked example (real case): AH2 +0.25 at 2.36 at bookmaker A for EUR 100 against the home win (1) at 2.10 at bookmaker B for EUR 112.38. Away wins: +EUR 23.62. Home wins: +EUR 23.62. But a DRAW (the gap): the home leg loses, half the AH stake comes back and the other half wins: -EUR 44.38. You collect 23.62 on every non-draw and pay 44.38 when the draw lands. #### The value: how many wins one loss costs OddStorm prints each Polish middle's VALUE: the loss divided by the win, plus one. The example is (44.38 / 23.62) + 1 = 2.88: roughly, one gap hit eats two wins. A value of 1.92 means one hit eats less than one win, so alternating win-loss still leaves profit. Lower value = safer Polish middle. That is the inverse of regular middles (where higher value is safer), and it is the single number to filter by. > **Tip:** Prefer low-value Polish middles and gaps that are genuinely rare for the fixture (a draw between mismatched teams, an exact narrow margin). The football knowledge you already have finally earns its keep here. #### Playing them long-term Polish middles are a volume game with three rules: - Filter by value first (as low as you can find), percentage second. A fat percentage with a value of 4 is a trap for your variance. - Keep stakes uniform relative to bankroll so one gap hit never erases more than a few wins' worth of progress. - Log gap hits separately in your records. If gaps hit far more often than the value implies over dozens of plays, your gap selection (not the math) needs fixing. #### Where to go next If middles and Polish middles appeal to you, the Asian handicap guide explains the quarter-lines that create most of these gaps in the first place. ### [Asian handicap, the arber's workhorse](https://www.oddstorm.com/guides/asian-handicap) Updated 2026-10-18. An Asian handicap (AH) gives one team a virtual head start, turning a three-outcome football match into a two-outcome bet. For arbers AH is the workhorse market: two-outcome legs pair cleanly into surebets, and the quarter-lines create the gaps that middles and Polish middles live on. You do not need to LIKE betting handicaps to need this page: a huge share of the arbs OddStorm shows you has an AH leg, and misreading a quarter-line is one of the few ways to lose money on a correctly priced arb. #### The idea in one minute Add the handicap to the team's real score at full time. AH1 -1 means the home team starts one goal behind for your bet: they must win by two or more for the bet to win. AH2 +0.5 means the away side wins your bet on any draw or away win. The draw as a separate outcome disappears, leaving exactly two sides. When the adjusted score lands exactly level, your stake is returned (a push). That refund mechanic is what makes whole-number lines gentle and quarter lines interesting. #### Whole, half and quarter lines Three families of lines, distinguished only by what happens at the boundary: - Whole lines (0, -1, +2): a push is possible. AH 0 is simply draw-no-bet: lose the draw, get your stake back. - Half lines (-0.5, +1.5): no push possible, the bet always wins or loses. AH1 -0.5 is identical to 'home to win'. - Quarter lines (-0.25, +0.75, -1.25): your stake splits in half across the two neighboring lines. AH1 -0.25 = half on 0, half on -0.5. - The display differs per bookmaker: -0.25 may appear as '0, -0.5' or '-1/4'. Same bet, different notation. > **Note:** Reading example: AH1 +0.75 means half your stake on +0.5 and half on +1. Home wins or draws: both halves win. Home loses by exactly one: the +0.5 half loses, the +1 half pushes (refunded), so you lose only half the stake. Home loses by two or more: everything loses. #### Why quarter lines matter to arbers Those half-void boundaries are exactly the gaps that middles and Polish middles are built from: a quarter-line leg against a plain leg leaves one narrow result band where the settlement differs, with the loss softened to half a stake. The calculator handles the split math; what it cannot do is stop you from confusing +0.75 with -0.75 at placement time. > **Note:** The same one-goal margin can be a full win, a half win, a push, a half loss or a full loss depending on the line. Before confirming any AH bet, say out loud what happens if the match ends level and if your team loses by exactly one. #### AH in arbitrage practice Three practical rules for AH legs in arbs: - Verify the LINE, not just the odds. An arb computed for AH1 -0.75 is a different bet at AH1 -1.25 even when the odds match. - Sharp books (Pinnacle) publish the tightest AH prices and move them first: place the AH leg at the sharp book before the soft leg whenever the arb allows. - Watch which score the line pivots on when pairing AH with European handicaps or 1X2 legs: coverage must be exact, not approximate. OddStorm only combines legs that truly cover, but manual improvisation is how people invent uncovered gaps. > **Warning:** Never 'repair' a moved AH arb by taking the neighboring line by hand. A quarter-line step changes the covered results, and the leftover gap is precisely where the match will land the week you least afford it. #### Where to go next With AH mechanics in hand, the middles guide shows how quarter-line gaps become paid opportunities, and the three-way handicap guide covers AH's European cousin where the draw stays alive. ### [Moneyline and draw no bet](https://www.oddstorm.com/guides/moneyline-and-draw-no-bet) Updated 2026-07-02. Moneyline is the plain 'who wins' bet: two outcomes in sports without draws, and in football usually offered as draw no bet (DNB), where a draw refunds your stake. DNB is mathematically identical to Asian handicap 0, and that equivalence is free money for arbers who notice pricing differences between the two labels. Two-way winner bets look like the simplest markets on the board, and that's exactly why they trip people: 'Team A to win' can settle three different ways depending on what the market does with the draw and the clock. This guide separates the flavors, shows the AH 0 twin pricing in numbers, and lays out the pairing rules that keep a DNB leg genuinely covered. #### Moneyline in football terms In US sports the moneyline is simply the match winner, two-way, no draw exists. Football has a draw, so the two-way 'winner' bet exists in two flavors: DNB (draw = stake back) and 'to qualify / lift the trophy' style bets in knockout rounds (draw = extra time decides, no refund). Those two flavors are DIFFERENT bets: a 90-minutes DNB and a 'to qualify' leg do not cover the same outcomes even when both say 'Team A'. Every leg in an arb must state its settlement window: 90 minutes, or including extra time. #### DNB = AH 0, priced twice Draw no bet and Asian handicap 0 settle identically on every result: win on your team, refund on the draw, loss otherwise. Bookmakers nevertheless price them on different pages, sometimes with different margins, and scanners exploit exactly that: an arb can exist between DNB at one book and AH 0 (or the 1X2 legs replicating it) at another. > **Note:** Equivalence in numbers: 'Team A DNB at 1.90' and 'Team A AH 0 at 1.93' are the same bet at different prices. If you ever bet the pair manually, always take the higher of the twins; when OddStorm shows the arb, the right side is already chosen. #### Pairing rules for arbs Moneyline and DNB legs pair cleanly, with three cautions: - Settlement window first: 90-minute markets pair with 90-minute markets. A 'to qualify' leg silently includes extra time and penalties. - A DNB leg against a plain away win does NOT cover the draw's other side: the classic clean pair is DNB (or AH 0) against X2 or 1X, letting the refund absorb the draw. - Notation traps: some books label AH 0 as 'level ball', some fold DNB into the handicap page. Same market, three names; check the settlement terms, not the label. #### Where to go next The handicap family continues in two guides: Asian handicap (the two-way workhorse) and the three-way European handicap where the draw stays a live outcome. ### [Three-way (European) handicap](https://www.oddstorm.com/guides/three-way-handicap) Updated 2026-07-02. A European handicap (EH) applies a whole-goal head start like AH does, but keeps three outcomes: the favorite covers, the underdog covers, or the ADJUSTED score lands level, which is its own bettable draw. No pushes, no refunds: one of the three simply wins. The danger in EH isn't the market itself: it's the habits you carry over from Asian lines, where a level score means your stake back. Below you'll find the settlement logic step by step, the three differences from AH that cost real money, and why EH legs quietly power some of the longest-lived cross-market arbs. #### How it settles Add the handicap to the score, then read the result as a normal 1X2. With EH -1 on the home side: home wins by two or more = the handicap home win. Home wins by exactly one = the handicap DRAW. Anything else = the handicap away win. Because all three outcomes are priced, the 'draw by handicap' often carries juicy odds on mismatched fixtures. > **Note:** Example: EH -1 on a big favorite. Final score 3:1 = handicap home win. 1:0 = handicap draw (the adjusted score is 0:0). 1:1 = handicap away win. Compare AH -1 on the same match: the 1:0 result would be a push and your stake would come back. In EH there is no refund; that 1:0 loses the home-side bet entirely. #### EH vs AH: the differences that cost money The three differences an arber must never blur: - Outcome count: EH is three-way (1, X, 2 on the adjusted score), AH is two-way. An EH leg can only be fully covered by legs that absorb the handicap draw. - No stake refunds in EH, ever. The AH intuition 'level = money back' will settle as a straight loss in EH. - Lines are whole numbers only (EH -1, -2): no halves, no quarters, no split stakes. > **Warning:** The classic blown arb: covering AH -1 with 'EH +1 on the other side' by hand. The exact one-goal margin pushes on the AH leg but LOSES the EH leg you thought was covering it. The two handicap families do not mirror each other one-to-one. #### EH legs in arbs EH's three-way structure makes it the cross-market glue on the underdog side: EH2 +2.0 (away wins, draws, or loses by one) pairs naturally against AH1 -1.5 (home by two or more), covering every result between two bookmakers. OddStorm computes these EH-AH bridges automatically; they are among the longest-lived arbs because so few bettors read both notations fluently. #### Where to go next If the adjusted-score logic clicked, the Asian handicap guide completes the picture with the half and quarter lines, and the middles guide shows what to do with the gaps between lines. ### [Back/Lay surebets](https://www.oddstorm.com/guides/back-lay-surebets) Updated 2026-10-18. A Back/Lay surebet pairs a normal bet at a bookmaker (the back: it WILL happen) with the opposite position at a betting exchange like Betfair (the lay: it will NOT happen). When the bookmaker's price beats the exchange's lay price by more than the commission, the profit is locked whichever way the match goes. Back/Lay is the gentlest form of arbitrage on your bookmaker accounts and the easiest to misunderstand on the exchange side, because a lay stake is not what the number suggests. Five minutes here saves real confusion later. #### What a lay bet actually risks Laying means playing the bookmaker's role: you offer the bet and pay out if the outcome happens. When you lay EUR 113.21 at odds 1.39, you are not risking 113.21: you stand to WIN 113.21 (someone's back stake), and you risk the payout above it, called the liability: 113.21 x 1.39 - 113.21 = EUR 44.15. The exchange locks the liability from your balance while the bet is open. Read every lay twice: the stake is what you can win, the liability is what you can lose. > **Note:** Worked example (real OddStorm case): back X2 (draw or Lupa Roma) at 1.50 with Bet365 for EUR 100; lay X2 at 1.39 on Betfair with a lay stake of EUR 113.21 (liability EUR 44.15). If X2 happens: win 50 at Bet365, pay 44.15 at Betfair: +EUR 5.85. If it does not: lose 100 at Bet365, win 113.21 minus 6.5 percent commission = 105.85 at Betfair: +EUR 5.85. Locked either way. #### Commission is part of the odds Exchanges charge commission on net winnings (Betfair's base rate differs per market and account; the example uses 6.5 percent). The commission is why a lay at 1.39 is NOT automatically profitable against a back at 1.50: the calculator must shave it off the exchange side before declaring an arb. In OddStorm the default exchange commission is 2 percent, and you set your own rate in the Comm.% column of the Bookmakers panel (web app and desktop app); a rate under 2 percent isn't accepted. The Back/Lay calculator prices every opportunity with YOUR rate, not a generic one. Enter the rate your account actually pays; a wrong commission silently turns thin arbs into losses. #### Why arbers love Back/Lay Three properties make Back/Lay the account-friendly arm of arbitrage: - Exchanges never limit winners: the lay side of every arb sits somewhere that does not care how sharp you are, so only one side of your activity is visible to a bookmaker. - One counterparty for many arbs: instead of ten soft books on the second leg, the exchange covers them all, simplifying money logistics. - Clean exits: placed one leg and the price moved? The exchange usually still offers SOME lay price, so you can close the position for a small, known cost instead of holding a naked bet. > **Tip:** The constraint is liquidity: an exchange price is only real for the amount actually waiting at it. Check the available volume before sizing the back leg, especially on smaller leagues and InPlay. #### Back/Lay in OddStorm Back/Lay surebets are a separate feed in the OddStorm Desktop App (PreMatch and InPlay), with the exchange commission and liquidity built into the calculation and the lay stake and liability precomputed. The desktop app is Windows-only; that is where Back/Lay lives. #### Where to go next Back/Lay pairs naturally with account longevity: the limitation-avoidance guide covers the soft-bookmaker side of the same strategy. ### [Why surebets exist (and vanish)](https://www.oddstorm.com/guides/why-surebets-exist) Updated 2026-10-15. A surebet is a temporary disagreement between bookmakers, and bookmakers disagree constantly because each prices matches with its own models, traders and customers. The disagreement is real money while it lasts, and it usually does not last long. Understanding why tells you exactly how fast you must be. Knowing where an arb came from changes how you play it: a slow book lagging the news is a gift, while a spectacular percentage is usually an error the bookmaker can void. The rest of the page sorts the four sources, puts honest numbers on lifespans, and shows how the odds history tells a live price from a ghost. #### Where disagreements come from Four engines produce nearly every arb you will ever see: - Reaction speed: news (lineups, injuries, weather) moves the sharp books within seconds; slower books follow minutes later. The lag between them is an arb window. - Customer balancing: a bookmaker drowning in bets on one side shades its odds to attract the other side, drifting away from the market consensus on purpose. - InPlay chaos: during a match every dangerous attack reprices everything. Books update at different rhythms, so live arbs are more frequent AND larger, with lifespans measured in seconds. - Plain errors: a typo, a misplaced line, a model glitch. These create the spectacular percentages, and they are the ones bookmaker terms allow to void. Treat 10 percent and up as radioactive. #### How long an arb lives PreMatch arbs between big books commonly live minutes; niche-league and cross-market arbs can survive longer because fewer eyes check them. InPlay arbs live seconds: the next match event reprices one leg and the window shuts. Scanner speed decides which part of that lifetime you see. OddStorm delivers InPlay surebets within 1 to 3 seconds of the odds appearing, so you receive the window near its opening, not after other arbers have eaten it. PreMatch odds are scanned every 15 to 180 seconds depending on the bookmaker, the sharp ones most often to catch their moves fast. > **Note:** An arb that is STILL visible after many minutes deserves suspicion, not celebration: either the market is illiquid, or one leg is stale, or the price is an error waiting to void. Check the odds history before trusting an old arb. #### The odds history is your lie detector Every OddStorm arb shows the odds history with 'seen' and 'change' timestamps: how the price moved and how fresh each leg is. A leg that has been flapping every few seconds will not wait for your second placement; a leg frozen for an hour on a busy market may not exist at the bookmaker anymore. > **Tip:** Ten seconds of reading the history before placing beats thirty minutes of emailing support about a leg that moved. Fast-moving history = place that leg FIRST or skip the arb. #### When the odds move mid-arb anyway It will happen. The damage-control ladder, in order: - Take the best remaining price on the uncovered side immediately, even at a small locked loss. A known -1 percent beats an open gamble. - If an exchange lists the market, close there: lay off the exposure for a fixed cost. - Log it and study the pattern. If one bookmaker keeps moving before your second leg, place its leg first in future arbs or drop it from fast pairs. #### Where to go next Speed is half the craft; the other half is not needing speed at all. The beginner-mistakes guide covers the placement discipline that keeps moved odds from hurting. ### [The arber's glossary](https://www.oddstorm.com/guides/betting-glossary) Updated 2026-10-17. Every term and abbreviation you will meet in OddStorm, at bookmakers and in these guides, defined in one line each. Bookmark this page; the first weeks everyone reads it daily. Grouped by theme: match results, handicaps, totals, exchange terms, and the arber's own slang. When a bookmaker's label differs from the standard one, the standard is listed and the guide for that market explains the variants. #### Match result markets - 1X2: the classic three-way market. 1 = home win, X = draw, 2 = away win, settled on 90 minutes plus stoppage time. - 1X / X2 / 12 (double chance): one bet covering two of the three outcomes; X2 wins on a draw or an away win. - DNB (draw no bet): your team to win; a draw returns the stake. Identical to AH 0. - To qualify: the team advancing to the next round, INCLUDING extra time and penalties. Not a 90-minute market. - Moneyline: two-way winner market in sports without a draw; in football usually means DNB. - BTTS (both teams to score): yes/no market on both sides scoring at least once. #### Handicaps - AH (Asian handicap): a goal head start making the match two-way; whole lines can push (stake back), quarter lines split the stake across neighboring lines. - EH (European handicap): whole-goal head start with the draw kept as a third outcome on the adjusted score. No refunds. - Push: the handicap-adjusted result lands exactly level on a whole AH line; the stake is returned. - Half win / half loss: quarter-line settlement where one half of the split stake wins or loses and the other pushes. - Level ball: bookmaker slang for AH 0. #### Totals - O/U (Over/Under): a bet on total goals above or below a line (2.5, 3, 3.25...). Whole and quarter lines push and split exactly like AH. - Goal line: another name for the Over/Under line, especially in Asian books. - Team totals: Over/Under on ONE team's goals; do not pair against match totals, coverage differs. - Corners / cards markets: totals on corners or bookings; settle on different data feeds per bookmaker, so verify rules before arbing them. #### Exchange terms - Back: the normal bet, that something WILL happen. - Lay: the opposite position, that it will NOT happen; you play the bookmaker and pay out if it does. - Liability: the amount a lay bet can lose (lay stake x (odds - 1)); the exchange locks it from your balance. - Liquidity: the money actually waiting at a price on the exchange; a price is only real up to its liquidity. #### Arber's slang - Arb / surebet: a set of bets covering every outcome at combined odds guaranteeing profit; arber: the person placing them. - Leg: one bet inside an arb. Every arb has two or more legs at different bookmakers. - Middle: an arb whose legs leave a gap where both win; Polish middle: the inverse, the pair pays a small profit everywhere EXCEPT the gap, where it takes a known loss. - Palp (palpable error): an obviously wrong price; bookmaker terms allow voiding bets taken on it. The reason 10 percent arbs are traps. - Soft / sharp bookmaker: recreational-focused books with slow lines and limits for winners, versus low-margin books (Pinnacle, exchanges) that welcome winners and move lines first. - Limitation (gubbing): a bookmaker cutting your maximum stakes or banning promotions because your betting looks professional. - Odds history ('seen' / 'change'): OddStorm's per-leg record of when a price was last confirmed and how it moved; the arber's lie detector. #### Where to go next Terms make sense fastest in context: the what-is-arbitrage guide uses most of this page in three minutes of reading. ## Guides: Playbook ### [Avoiding bookmaker limits](https://www.oddstorm.com/guides/avoid-bookmaker-limits) Updated 2026-07-02. Soft bookmakers limit accounts that look professional. You cannot make an account unlimitable, but you decide how loudly your betting announces itself: stake rounding, market choice, withdrawal habits and error discipline together buy months or years of extra account life. This is the craft half of arbitrage. The math half guarantees the profit per arb; this page protects the accounts that let you keep placing arbs at all. #### What a limitation is A bookmaker that decides you are unprofitable to serve cuts your maximum stakes (sometimes to pennies), excludes you from promotions, or closes the account to new bets. Your balance and open bets stay safe and withdrawable: reputable books restrict future betting, not your money. It is a business decision inside their terms, usually made by an automated risk model plus a trader's review. Nothing about it is personal, and nothing about it is appealable in practice: prevention is the whole game. #### The tracks that give arbers away Risk models look for patterns that separate arbers from recreational bettors: - Unrounded stakes: EUR 173.42 on a Tuesday handicap is a calculator's number, not a fan's. - Only ever betting moved prices: hitting every stale line and error minutes before the market corrects. - One-sided market diet: exclusively niche handicaps and goal lines, never a popular-league 1X2 or an accumulator. - Deposit-bet-withdraw cycles: money that arrives, bets once and leaves screams professional. - Betting the maximum allowed stake repeatedly, especially on small-league markets. #### The habits that extend account life None of these break any rule; they simply make your account look like everyone else's: - Round every stake to natural amounts (20, 50, 100, 150). The lock loses cents; the account gains months. - Skip palps and 10-percent-plus arbs entirely: error-sniping is the fastest known route to a risk review. - Withdraw rarely, in round amounts, and leave a working balance in the account. Frequent withdrawals trigger reviews at many books. - Mix in occasional normal-looking bets on big matches (the soft side of an arb on a popular 1X2 often does this for free). - Spread volume across enough bookmakers that no single soft book carries your whole turnover. > **Tip:** Priorities when an arb conflicts with the habits: skip the arb. Individual arbs are infinite; a clean account at a generous soft book is not. #### When it happens anyway Every serious arber gets limited eventually. Withdraw calmly (your money is not at risk), keep the account for the occasional recreational-size bet, and shift that book's share of your volume to the others. Back/Lay arbing through an exchange absorbs a lot of lost soft-book capacity, and sharp books never limit in the first place. > **Warning:** Do not 'solve' a limitation with a second account under a relative's name. That breaks bookmaker terms everywhere and in some places the law, risks confiscated balances, and arbitrage simply does not need it: there are always more bookmakers. #### Where to go next The soft-vs-sharp guide explains WHICH books limit and which never will, and the Back/Lay guide covers the exchange route that sidesteps the problem entirely. ### [Palpable errors and cancellations](https://www.oddstorm.com/guides/palpable-errors-and-cancellations) Updated 2026-07-02. A palpable error (palp) is a price so obviously wrong that bookmaker terms allow the bet to be voided or resettled at corrected odds. For an arber a voided leg means the OTHER leg suddenly stands alone as a normal gamble. Recognizing palps before betting them is a core survival skill. Palps are the reason the juiciest-looking arbs are the most dangerous ones. This page teaches the smell test and the recovery playbook for the day a leg vanishes anyway. #### What counts as a palpable error Typos and slipped lines: odds of 8.10 where the market says 2.10, a handicap given to the wrong team, a decimal point in the wrong place, Over and Under swapped. Bookmaker terms (every single one has this clause) let them void such bets or restate them at the 'true' price, sometimes hours after acceptance. The practical definition for an arber: any price far enough from the market consensus that the arb percentage looks like a gift. Bookmakers do not void normal pricing disagreements; they void gifts. > **Note:** Real pattern: a wrongly entered handicap showed both home teams with the goal advantage, producing a 30-percent-plus 'arb'. Bets on it were voided the same day. The other legs, placed at three bookmakers, all stood as open gambles. #### The smell test Four checks, ten seconds total, before betting a fat arb: - Percentage: above roughly 10 percent, assume error until proven otherwise. The steady range is 1 to 5. - Consensus: compare the suspicious leg against two or three other books on the same market. One book far from everyone is the signature of a palp. - Odds history: OddStorm's history shows when the price appeared. A weird price that JUST appeared and no other book followed is fresh error, not fresh news. - News check: sometimes one book truly is first (a lineup leak). If the sharp books are moving the same direction, it is news; if only one soft book jumped, it is a typo. #### When a leg gets voided anyway You now hold an uncovered bet. In order: - Re-cover immediately at the best available price, even locking a small loss: a known -2 percent beats an open coin flip. - If an exchange lists the market, close the exposure there: lay what you backed (or back what the void left exposed). - If the bookmaker offered resettled odds instead of a void, redo the arb math with the new price before deciding to keep or cover. > **Tip:** Decide your palp policy in advance and write it down: 'above X percent I skip, on void I cover instantly at any price better than Y'. Decisions made during the adrenaline are the expensive ones. #### Where to go next Palps are one of the four ways a correct arb loses money; the beginner-mistakes guide covers the other three, and the limits guide explains why error-sniping also shortens account life. ### [Account verification without the pain](https://www.oddstorm.com/guides/bookmaker-verification-kyc) Updated 2026-07-02. Every bookmaker will verify your identity (KYC), and by default it happens at the worst moment: when you first try to withdraw, freezing your money for days or weeks. The fix is simple and absolute: verify every account on day one, before it holds a single working euro. KYC is a one-time setup problem, not a recurring fight: one well-prepared document folder clears bookmaker after bookmaker, and one money-routing habit keeps every withdrawal review short. Both take an evening, and this page shows exactly what goes in the folder and which habit to lock in. #### Verify before you need it Verification takes from hours to weeks depending on the bookmaker's queue and how clean your documents are. Done at signup, that delay costs nothing; done at withdrawal, it locks exactly the money you were counting on for the next arbs. There is no third option: the check WILL happen. > **Tip:** Make verification part of account opening in your action plan: register, upload documents, small deposit, small test withdrawal. An account is not 'open' until a withdrawal has completed. #### The documents to have ready One folder on your computer, prepared once, reused everywhere: - Identity: passport or ID card, both sides, corners visible, no glare. Name must match your account EXACTLY. - Address: utility bill or bank statement under 3 months old showing the same address you registered with. - Payment proof: e-wallet screenshot showing your name, email and the transaction to the bookmaker (much friendlier than photographing bank cards). - Source of funds (bigger accounts): a bank statement or payslip. Rarely asked early, standard at higher volumes. #### The same-route rule for money Bookmakers return money by the road it arrived on: deposit by e-wallet and you withdraw to that e-wallet; deposit by card and you withdraw to that card. Mixed requests get rejected, and each rejection restarts a review. Pick ONE deposit method per bookmaker (the e-wallet) and never improvise. > **Note:** This rule is anti-money-laundering law, not bookmaker whim: no support ticket bends it. It is also the strongest argument for running your whole bankroll through one e-wallet hub. #### Keeping every future check smooth - Identical details everywhere: one spelling of your name, one address, your own payment instruments only. - Update documents proactively when you move or a card expires; a stale address fails silently at the next review. - Answer re-verification requests same-day: accounts flagged 'awaiting documents' are frozen for withdrawals. - Never verify with borrowed documents or let someone else use your account: that is the one KYC failure with no recovery. #### Where to go next The e-wallet guide sets up the money hub that makes the same-route rule painless. ### [E-wallets: the arber's money hub](https://www.oddstorm.com/guides/e-wallets-for-arbers) Updated 2026-10-18. Arbitrage means money parked at many bookmakers that constantly unbalances: winners grow fat while losers run dry. An e-wallet (Skrill and Neteller are the industry standards) is the hub that rebalances it all in minutes instead of bank days, with one verification instead of ten. Nobody quits arbitrage because the math failed; people quit because moving money became a part-time job. One hub account solves most of it. #### Why not just use your bank card Three reasons the card loses to the wallet: - Speed: wallet-to-bookmaker transfers are instant both ways once verified; card withdrawals crawl through 2-5 bank days per bookmaker. - The same-route rule: money returns the way it came. With a wallet hub, every bookmaker's money comes back to ONE place, ready for redeployment; with cards you juggle per-book routes. - Privacy and bank hygiene: one gambling counterparty (the wallet) on your bank statement instead of fifteen bookmaker charges, which some banks and mortgage reviews frown at. #### Which wallet Skrill is the arber default: available in most countries, with instant transfers and fees that reward volume. Neteller (same parent company) is the standard backup: coverage nearly as wide, and a second hub keeps you moving when one wallet reviews your account. PayPal is accepted at fewer bookmakers and its per-transfer fees bite at arbitrage volumes: fine as a consumer tool, not as the hub. Whatever you choose, check the CURRENT fee table before committing: fees change and volume tiers (VIP programs) can cut them substantially. > **Note:** Open the wallet in the SAME currency as most of your bookmaker accounts (EUR for most of Europe). Every currency conversion inside the loop is a silent fee on every rebalance, and at arb margins of 1 to 3 percent, conversion costs can eat a real share of the profit. #### Setting up the hub properly - Verify the wallet fully on day one (identity + address), before wiring real volume through it: wallet KYC freezes hurt exactly like bookmaker ones. - Fund every bookmaker FROM the wallet, never from cards, so all withdrawal routes lead home to the hub. - Keep the reserve (10-20 percent of bankroll) in the wallet, ready to top up whichever bookmaker runs dry mid-session. - Rebalance on a weekly rhythm in round amounts rather than after every arb: fewer, calmer transfers are cheaper and quieter. > **Tip:** Check whether your volume qualifies for the wallet's VIP tier: lower fees, higher limits and faster support are standard perks, and arbers hit the thresholds sooner than they expect. #### Where to go next The KYC guide covers the verification the wallet and every bookmaker will run, and the bankroll guide decides how much should sit in the hub at all. ### [VPN and account security](https://www.oddstorm.com/guides/vpn-and-account-security) Updated 2026-10-18. A VPN is a security tool, and arbers with money spread across a dozen gambling accounts need security more than most. What a VPN is NOT is a residency trick: bookmaker access follows your verified identity and documents, and KYC always wins against an IP address. Arbers ask about VPNs for two different reasons, and the answers point in opposite directions: for protecting a dozen funded logins, an emphatic yes; for reaching bookmakers that don't serve your country, an expensive no. This page covers both, starting with the security setup worth copying. #### The real security case You run significant balances behind a dozen logins. Treat them like the bank accounts they effectively are: - A VPN encrypts your traffic on hotel, cafe and airport networks: the realistic attack on an arber is a snooped session on public WiFi, not a movie-style hack. - A password manager with unique passwords per bookmaker beats any browser-saved list. One reused password is one breached bookmaker away from all your balances. - Enable two-factor authentication everywhere it exists: the e-wallet first (it is the hub), then every bookmaker that offers it. - Keep a stable connection profile for betting sessions. Bouncing between exotic IP locations mid-session looks exactly like account takeover and triggers security reviews. #### What a VPN cannot do for you Bookmaker availability is legal, not technical: a book serves the countries where it holds licenses, and it verifies WHERE YOU LIVE through documents, payment methods and data, not through your IP. A VPN may let you SEE a website, but the account still requires proof of a real address in a served country. Betting through a VPN on an account whose registered country you do not actually live in breaks the bookmaker's terms, and the discovery usually happens at withdrawal time, when the KYC review compares everything. The arithmetic of arbitrage never requires that risk: work with the bookmakers that lawfully serve your country (our live list shows the ones we scan; your local regulator says which are licensed where you live). > **Warning:** Confiscated-balance stories in arbitrage forums almost all start with 'I used a VPN and someone else's address'. No arb percentage justifies an unwithdrawable balance. #### Where to go next Account longevity is mostly behavior, not networking: the limits guide covers the habits that matter, and the KYC guide the paperwork that makes every review boring. ### [Settlement rules: the same bet that isn't](https://www.oddstorm.com/guides/settlement-rule-differences) Updated 2026-10-20. An arbitrage covers every outcome only if both legs settle on the SAME definition of the outcome. Two bookmakers can call a market by the same name and settle it differently (extra time, abandonments, what counts as a corner), and inside that difference your 'covered' arb has a hole. Settlement gaps are nastier than moved odds because nothing warns you: both bets accept, both slips confirm, and the hole only shows when a cup tie goes to extra time. The traps below form a short, stable list, and the pre-bet discipline that closes them costs about a minute per new market. #### Why rules differ at all Every bookmaker writes its own settlement terms, inherited from different traditions (UK, continental, Asian) and different data providers. Football's core 1X2 is standardized on 90 minutes plus stoppage almost everywhere, which is why most arbs are safe; the edges (cup ties, statistics markets, abandoned matches) are where definitions drift apart. #### The classic traps - Extra time: 'to qualify' and some knockout winner markets include extra time and penalties; 1X2 and most AH/totals do not. Pairing a 90-minute leg with an including-extra-time leg leaves the draw-then-decider results uncovered. - Abandoned and postponed matches: some books void everything, some settle markets already decided (a first-half line on a match abandoned at 60 minutes), and the void windows (24h, 48h, 'next scheduled day') differ. - Statistics markets: corners taken vs corners awarded, cards counted per player vs per incident, shots on target per provider. Two feeds, two answers, one 'covered' arb. - Player markets: 'anytime scorer' with own goals excluded at one book and included at another; players who never enter the pitch void at some books and lose at others. - Dead-heat and pushes: whole-line AH pushes refund, EH never refunds; a dead heat on outright markets divides stakes by book-specific rules. > **Note:** Concrete case: a cup quarterfinal, leg A 'Team X to qualify' at book 1, leg B 'Team Y to win' (90 minutes) at book 2. Team Y wins in extra time: leg B already LOST at full time (it was a draw), and leg A loses too. Both legs down on one match: the gap was the settlement window, not the odds. #### The pre-bet discipline OddStorm matches every leg to the same event and can combine different markets and lines, but it doesn't read the bookmakers' settlement terms. The discipline below is for the seconds at the bookmaker's site, where YOU pick the actual market from their list: - Confirm the settlement window on both slips: 90 minutes vs including extra time is written on the market page of every serious book. - On statistics and player markets, read the book's settlement note the FIRST time you use that market at that book; note it in your bookmaker sheet forever. - When a match is at risk of abandonment (weather, crowd trouble) skip the arb: void-rule roulette between two books is not a bet you priced. > **Tip:** One minute of reading a market's terms once per bookmaker beats re-learning it from a lost 'sure' bet. Your bookmaker sheet is the memory. #### Where to go next The handicap guides (Asian and three-way) cover the push-refund mechanics behind the last trap above. ### [Soft and sharp bookmakers](https://www.oddstorm.com/guides/soft-vs-sharp-bookmakers) Updated 2026-07-02. Soft bookmakers are the recreational brands: slower odds, bigger margins, quick to limit winners. Sharp bookmakers price with thin margins, move first on news, and never limit you. Nearly every arb you will place pairs one of each, so an arber needs to understand both species. The soft/sharp split explains most of arbitrage in one sentence: arbs appear when a slow book has not yet followed a fast one. You profit from the lag, which means living with a foot in each world. #### Soft bookmakers The household names built for recreational bettors: Bet365, Bwin, Ladbrokes, William Hill and every locally famous brand. Margins run higher (mid-to-high single digits), odds follow the market with a delay, and the business model tolerates winners poorly: consistent sharp-looking profit earns stake limits. They are still where your profit comes from. The lagging leg of an arb sits at a soft book almost by definition, their stake limits on popular leagues are generous, and reputable ones always pay what you have won even after limiting you. The craft (rounded stakes, no palps, calm withdrawals) exists precisely to stretch your welcome there. #### Sharp bookmakers Pinnacle is the archetype (and OddStorm scans it as an official partner with real-time data); betting exchanges like Betfair play the same role structurally. Margins around 2-4 percent, prices moved by models and professional flow within seconds, and an explicit welcome-winners policy: no limits for being good. Arbs BETWEEN two sharp books are rare and thin: they agree with each other too quickly. Their role in your arbitrage is the anchor leg: the reliable, high-limit, never-limited side that the soft book's lagging price gets paired against. #### How the two work together in an arb A typical OddStorm arb: news moves Pinnacle's line at second zero; a soft book still shows the old price at second thirty. You back one side at the soft book's stale price and the other at the sharp book, and the disagreement pays you. The sharp leg also tells you which way prices are heading: place the sharp (fast-moving) leg first. > **Note:** This is why 'which bookmakers should I open' has a canonical answer: sharp anchors first (they are in most arbs), then as many quality soft books as your country offers. The live availability of each is on our Supported Bookmakers page. #### Working both sides, long-term - Treat sharp accounts as infrastructure: fund them well, they carry the volume and never punish you for winning. - Treat soft accounts as consumable: protect them with the limits-avoidance habits, and expect to lose some eventually anyway. - When a soft account dies, redistribute: more soft books, or shift weight to Back/Lay through the exchange, where limitation does not exist. #### Where to go next The limits guide is the soft-book survival manual, and the Back/Lay guide covers the exchange side of the sharp world. ### [Clone bookmakers](https://www.oddstorm.com/guides/clone-bookmakers) Updated 2026-10-20. Many bookmaker brands are the same product underneath: one platform, one odds feed, many storefronts. These clones matter to arbers twice: as spare capacity when a main brand limits you, and as a trap when 'the same' bookmaker shows slightly different odds on a different domain. The betting industry produces brands much faster than it produces platforms, which is why your 'new' local bookmaker often prices exactly like one you already hold. Understanding that machinery pays twice over: you'll plan account openings by family instead of by logo, and you'll solve most 'wrong odds' mysteries by glancing at your address bar. #### What a clone is White-label and skin operations let one operator run dozens of brands: same odds engine, same markets, same risk department, different logo and domain. Asian operators also run mirror domains: other addresses of one brand, carrying that brand's odds. OddStorm scans the bookmakers in its in-app bookmaker list (that list is the reference), not every clone of their families. When your local storefront is a clone of a family we scan, the odds usually match, but 'usually' is doing real work in that sentence. #### Why arbers care - Spare accounts after a limit: a clone of a book that limited you is a NEW account contract on the SAME odds, lawfully opened in your own name. Same odds, fresh welcome, often a fresh signup bonus too. - Risk correlation: clones often share a risk department. Getting limited across several sister brands at once happens; do not count five clones as five independent soft books in your planning. - Coverage arithmetic: when choosing which account to open next, a genuinely independent bookmaker adds more new arbs than another skin of a family you already hold. #### The exact-domain rule A mirror of a bookmaker OddStorm covers is covered too: it's the same bookmaker at another address, with the same odds. A clone is a different brand, and its prices can drift from the brand OddStorm scans. If you bet at a clone while OddStorm scans another brand of the family, you will sometimes see odds that do not match the arb: not an error in the scan, an error in the storefront choice. Bet where the feed is; when reporting mismatched odds to support, always send the FULL domain you used. > **Warning:** 'You are our only client reporting mismatched odds at this bookmaker' is the classic clone symptom: everyone else is on the primary domain. Check your URL before checking anything else. #### Where to go next The live Supported Bookmakers page shows exactly which families OddStorm scans right now, and the soft-vs-sharp guide explains how to slot clones into your account planning. ### [InPlay arbing](https://www.oddstorm.com/guides/inplay-arbing) Updated 2026-07-02. InPlay is where arbitrage pays best: live odds move every second, so disagreements are bigger and more frequent than PreMatch. It is also where mistakes cost most, because every window lasts seconds. This guide is the graduation path and the session craft. The first time you open the InPlay feed, surebets appear and vanish every second and the alerts do not stop. That chaos is the product working (OddStorm delivers live arbs within 1 to 3 seconds of the odds appearing); this page is about making YOU as fast as the feed. #### InPlay vs PreMatch, honestly PreMatch gives you minutes per decision, smaller percentages, and money locked until matches settle. InPlay gives you seconds per decision, fatter percentages, more opportunities per hour, and same-day settlement that turns your bankroll over faster (which compounds into more monthly profit at the same bankroll). The honest ordering: start PreMatch until placement is automatic, then ADD InPlay sessions rather than switching. The two share one bankroll beautifully: PreMatch fills the quiet hours, InPlay concentrates on match windows. #### Are you ready for live? Graduate when all four are true: - You have placed 30+ PreMatch arbs without process mistakes: market found fast, both legs placed, no surprises at settlement. - You are logged in EVERYWHERE with money already distributed: there is no time to top up an account mid-window. - You know each bookmaker's live interface: where the market sits, how bet acceptance behaves, whether they delay live bets by a few seconds. - Your connection and machine are stable: a laggy session is a losing session, full stop. #### Session craft The habits that separate profitable live sessions from expensive adrenaline: - Pick your matches before kickoff (big leagues, liquid markets) and prefund the books that cover them; do not chase every fixture on Earth. - Place the fast leg first, always: the leg at the sharper book or the one whose odds history shows movement. Seconds decide whether leg two exists. - Bet acceptance delays are normal live: some books hold a live bet 5-10 seconds before confirming. Learn who delays and never place their leg second on a tight window. - Set a session stop rule (time or number of arbs). Live arbing concentrates; fatigue mistakes cluster in hour three. > **Tip:** Halftime and the minutes after a goal are the richest windows: books re-open markets at different speeds and disagree the most. Be at the desk BEFORE the break, not after it. #### Where to go next Pair this with the best-time-to-arb guide for weekly planning, and the why-surebets-exist guide for the mechanics of the windows you are racing. ### [The best time to arb](https://www.oddstorm.com/guides/best-time-to-arb) Updated 2026-07-02. If your hours are limited, spend them where the fixtures are: Saturday first, Sunday second, and within any day, the hours around kickoffs and the live windows of big matches. Arbitrage volume follows the football calendar almost mechanically. Most arbers work around a day job, which makes scheduling a profit decision, not a calendar detail. This guide maps the week's fixture volume, the in-day windows where prices move hardest, and how to turn a Saturday plus two free evenings into a plan that catches the fat part of the market. #### The weekly rhythm Arbs need matches, and the football week is lopsided: - Saturday is the king: around half of the week's fixtures, league play everywhere, soft books stretched across hundreds of markets. Most arbers' most profitable day, by volume alone. - Sunday carries roughly another third of fixtures: nearly as rich, slightly calmer. - Midweek (Tuesday to Thursday) brings the cup and continental nights: fewer matches but heavyweight liquid ones, with excellent InPlay windows in the evening. > **Note:** Monday and Friday are the thin days: fine for account maintenance, rebalancing through the e-wallet, and reviewing the log, so the weekend hours stay pure betting time. #### The in-day windows Within a match day, arbs cluster where prices move: the hour before mass kickoffs (lineups drop, soft books lag the news), the halftime break, and the minutes after every goal (books re-open and re-price at different speeds). A limited-time arber does better sitting fully focused through the Saturday 16:00 kickoff wave than grazing the whole day thinly. #### Planning a limited week With one free day, make it Saturday and prefund every account on Friday evening. With two, add Sunday. With scattered evenings only, take the midweek continental nights InPlay. Whatever the pattern, decide it BEFORE the week starts: arbs reward the arber who is already logged in, funded and watching when the window opens. #### Where to go next The InPlay guide covers the live windows in depth, and the realistic-profit guide turns your available hours into an honest monthly number. ### [Bonus hunting](https://www.oddstorm.com/guides/bonus-hunting) Updated 2026-10-15. Nearly every bookmaker pays new customers a deposit bonus, and arbitrage is the cleanest machine for converting those bonuses into withdrawable money: surebets grind through the rollover requirements while losing only the arb margin, which the bonus repays many times over. Ten new accounts on your arbing journey means ten paid bonuses. A typical welcome bonus repays a month of arb margins on its own, which is why experienced arbers treat account opening as a paid event rather than a chore. What follows is the rollover math from an arber's angle, plus the four terms in the fine print that decide whether a bonus is fuel or a trap. #### How bookmaker bonuses work The standard shape: deposit at least X and receive a matched bonus up to Y, which becomes withdrawable only after you have staked some multiple of it (the rollover), sometimes at minimum odds, within a time window. The bonus is real money with a work requirement attached; arbitrage is a way to do the work at near-zero cost. > **Note:** Generic example: deposit EUR 50, receive EUR 50 bonus, rollover 6x the bonus at odds 1.50 or higher within 30 days. You must stake EUR 300 before the EUR 50 is yours to withdraw. #### The rollover math, arber style A recreational bettor clears EUR 300 of rollover by risking EUR 300 at the bookmaker's margin, expecting to lose EUR 15-20 of it. An arber routes those same stakes through arb legs: every qualifying bet at this bookmaker is one leg of a surebet, covered at another book, so the expected cost of the EUR 300 turnover is roughly zero (you even lock small profits). The bonus arrives intact. Check that arb legs qualify: minimum odds requirements (1.50 is common) exclude the short leg of many arbs, so pick arbs whose leg at THIS bookmaker meets the minimum, and check that leg's odds before you place it. #### The terms that decide everything - Rollover multiple and base: 6x the BONUS is fine; 6x deposit-plus-bonus doubles the work. Read which one it is. - Minimum odds per qualifying bet, and whether both sides of your betting count (some books exclude certain markets). - Time window: 30 days of comfortable arbing can clear most rollovers; 7 days on a big bonus forces rushing. Plan before depositing. - Withdrawal before completion usually voids the whole bonus: park no money you might need mid-rollover. > **Warning:** Bonus terms explicitly ban 'covering bets across bookmakers' at SOME books, and bonus-abuse teams read betting patterns. Clear rollovers with the same discipline as normal arbing (rounded stakes, popular markets, no palps), and treat the bonus as a welcome gift, not a business model: it is one-time fuel per bookmaker family. #### Where to go next Bonuses are bankroll fuel: the bankroll guide decides where the freed money goes, and the clones guide explains why sister brands sometimes mean another welcome bonus on the same platform. ## Guides: Using OddStorm ### [Getting started with OddStorm](https://www.oddstorm.com/guides/getting-started-with-oddstorm) Updated 2026-10-18. OddStorm runs in your browser: create a free account, open the PreMatch or InPlay feed, and live surebets start flowing with the stakes already calculated. This tour takes you from registration to understanding everything on the screen. The free account needs no card and does not expire: profits show capped at 0.50 percent and event names stay hidden, which is exactly enough to learn the interface and watch the real rhythm of arbs before paying anything. #### Create the account Register with your email, confirm it, and sign in. Set your time zone in the Profile menu right away: every kickoff time in the app follows it, and a wrong zone is the classic reason a 'live' match looks upcoming. > **Note:** Use a real, reachable email: trials, receipts and any support conversation go through it, and support matches you by the registration address. #### The screen, in four pieces Open PreMatch (Surebets) or InPlay from the top menu. Every row is one arbitrage: - The percentage: the locked profit of the arb. Sorted best-first by default. - The legs: each shows the bookmaker, the market (1X2, AH, Over/Under...) and the current odds. The link icon next to a bookmaker in the outcomes panel opens its website; you find the event there yourself. - The calculator: click a row and it opens with the stakes already split; type your own stake on the leg the round button marks and press Calculate. - The age and odds history: how long ago each price was confirmed ('Seen') and how long ago it last changed ('Change'). Fresh legs = trustworthy arb. #### The Bookmakers panel On the left in PreMatch and InPlay sits the Bookmakers panel: tick the books you actually hold accounts at and the feed shows only arbs you can place. That filter turns the firehose into YOUR feed. Next to it, the Markets and Periods panels hide the bet types and periods you don't want, and a preset saves the whole setup so you can switch between setups from the sidebar. The live list of what we scan (with PreMatch and InPlay availability) is on the Supported Bookmakers page, which opens with a free account. #### Your first (paper) surebet Pick an arb between two bookmakers you hold, open the calculator, write down the stakes, then find both markets at the bookmakers WITHOUT betting. Check the odds still match, then watch the match settle. Twenty such dry runs teach the interface better than any manual. You need the event names for this, which the free view hides and a plan or the 24-hour trial shows. > **Tip:** A fat percentage is tempting, but read the odds history before you trust it: a price that has not been re-confirmed for a long time on a busy market may already be gone. #### When you are ready to unlock A subscription removes the profit cap and reveals every name: pick a tier (Pro, or Elite which adds Navigation), a product (PreMatch, InPlay, or both) and a duration (1, 6 or 12 months, plus a 1-week plan on Pro) on the pricing page. The 24-hour Elite trial (Monday to Thursday, one per user, requested from support at least 24 hours ahead from your registered email) is the cheapest way to feel the full feed. #### Where to go next The action plan sequences everything around the scanner (accounts, money, first bets), and the desktop app guide covers the Windows client that adds Navigation and Back/Lay surebets. ### [Filters and presets in the web app](https://www.oddstorm.com/guides/web-app-filters-and-presets) Updated 2026-10-15. The sidebar on every tool page decides which surebets reach your screen: the bookmakers you hold, the markets and periods you hide, the exchange commission and minimum liquidity, and your Settings. Save a setup as a preset and switch between setups from the top of the sidebar. Since September 2026 the web app has the desktop app's filters. That's a lot of control packed into a narrow column, and it cuts both ways: one forgotten setting can hide exactly the surebet you were waiting for. Here's what each part of the sidebar does, how presets keep your setups apart, and what to check when an arb seems to be missing. #### Where everything lives Open any tool page: Surebets, Middles or Polish Middles, under PreMatch or InPlay. The sidebar on the left has five sections (Settings, Bookmakers, Markets, Periods and Live Chat), and the Preset menu sits above them because a preset covers the first four at once. Every change asks for a fresh list straight away, so you see its effect without reloading. #### Bookmakers Tick the bookmakers you actually hold accounts at and the feed only shows arbs you can place. Each box moves through three states as you click it: empty, a tick and a square. The legend under the list names them: show odds for the tick, must exist for the square. Hide unchecked trims the list to the bookmakers you've marked. #### Exchange commission and minimum liquidity Two columns sit next to the bookmaker names: Comm.% and Min.Liq.. They're filled in and editable only for a bookmaker that has default values, which today means Betfair. Our scanners apply both when they build your list: - Comm.% is the exchange's commission. It lowers the exchange price the arb is worked out with. You can raise it to match your own rate, but you can't go below the default: a lower number snaps back to it. - Min.Liq. is the least money that has to be available at the exchange price. Any exchange price with less liquidity than your minimum is left out of your list. An empty field or 0 means the default. On the cards, an exchange leg shows the commission applied next to the exchange's name and the money available under Liquidity. In the calculator, the Comm. column holds the commission taken off that leg's price. > **Warning:** Minimum liquidity is easy to forget once it's set. Raise it and surebets on thinner exchange markets quietly drop out of your list. If another scanner shows a Betfair arb you can't find here, check Min.Liq. before anything else. > **Note:** Back/Lay surebets (a back bet at a bookmaker against a lay on the exchange) are still desktop-only. On the web, commission and liquidity apply to the exchange prices in your regular feed. #### Hiding markets and periods Both panels hide what you tick. They're filters, not a list of everything we scan: Markets shows the market types you can hide, from Goals: 1X2 and Goals: Asian Handicap to Corners: Over/Under. A market's box cycles through empty, a tick and a square, and the two marks don't do the same thing: - The tick hides an arb when that market is in all of its outcomes. - The square hides an arb when that market is in any of its outcomes. It's the wider net. The box at the top of the list ticks every market at once. Periods is simpler: Full time, First half and Second half, one tick each. Tick Full time and you're left with first- and second-half arbs only. Great if you only bet half lines, a nasty surprise if you ticked it by accident. > **Tip:** Want a market gone completely? Use the square. A tick only removes arbs where every outcome is in that market, so an arb that pairs it with another market stays in your list. #### Settings Settings holds the limits and alerts for the page you're on: - Arbitrage filter: Min % and Max %. On Middles and Polish Middles the limit is a value, not a percentage. - Alarm: a sound when an arb passes the level you set, with a list of sounds and a Play button to hear them first. - Show arbitrages if: conditions such as Legs are and, on PreMatch, Settled in hours. - On InPlay the same group adds live conditions, among them Event is on Half time, Current score is Draw and Odds lower than. Surebets, Middles and Polish Middles each keep their own Settings, because their limits mean different things. #### Presets The Preset menu at the top of the sidebar shows the preset in use, Default until you make your own. A preset keeps your bookmaker ticks, exchange fees, hidden markets and periods, and each tool's Settings. From the menu you can: - Switch: pick a name and the whole sidebar changes with it. - Save as a new preset: copies what's on screen under a new name and makes it the preset in use. - Rename: the pencil turns the name into a text field. Enter saves it, Escape keeps the old name. - Delete: asks first, then removes the preset with its bookmakers, markets, periods and settings. Delete the one you're using and you land back on Default. > **Note:** There's no separate save step: every change is saved to the preset in use as you make it. Want to try a stricter setup without losing the one you have? Save as a new preset first, then experiment. PreMatch and InPlay keep separate presets. Inside each, one preset serves Surebets, Middles and Polish Middles, while Settings stay per page. Default can't be renamed or deleted, every name has to be unique, and quotes and backslashes aren't allowed. A reload opens the preset you used last. Named presets need a signed-in account. Without one, the menu shows Sign in to save your own presets instead. #### Reset to defaults Settings, Bookmakers, Markets and Periods each have a Reset to defaults button in their header. It only works when there's something to reset, and it only touches the preset in use. Markets and Periods go back to hiding nothing, Settings to the page's defaults. Bookmakers asks before it acts, then ticks every bookmaker again and puts the exchange fees back to their defaults. #### When a surebet seems to be missing Another scanner shows an arb your list doesn't? Go through the sidebar in this order: 1. Preset: is the one in use the one you think it is? Each preset carries its own filters. 2. Bookmakers: both bookmakers of the arb are ticked. 3. Markets and Periods: neither the market nor the period is hidden, and remember the square hides more than the tick. 4. Min.Liq.: your exchange minimum isn't above the liquidity on offer. 5. Settings: the arb sits inside your Arbitrage filter limits, and nothing under Show arbitrages if rules it out. Reset to defaults in each panel undoes your changes in seconds. If the arb still doesn't show up with every panel at its defaults, it may sit on a market or bookmaker we don't cover: we don't scan every market at every bookmaker. ### [The OddStorm desktop app](https://www.oddstorm.com/guides/oddstorm-desktop-app) Updated 2026-10-16. The web app covers the full surebet feed in any browser, with bookmaker, market and period filters; the desktop app is the Windows client for the features that need deeper integration: Navigation and Back/Lay surebets. Same speed, same data, more control. You can arb profitably for months without installing anything, so the real question is when the desktop features start earning their place in your workflow. Here you'll find what each desktop-only feature does in practice, how to install it, and the honest answer for Mac users. #### What the desktop app adds Two things live only in the desktop app: - Navigation (Elite): on the bookmakers it supports, one click opens the bookmaker and walks straight to the event of the arb. Not every bookmaker we scan has it, so check yours with support first. - Back/Lay surebets: the bookmaker-vs-exchange feed with commission and liquidity built into the math. #### Install and sign in Download the installer from the Download page, run it, and sign in with your OddStorm account. The app doesn't update itself: when you sign in, it tells you if a new version is out, and the current version is always on the Download page. Then choose your bookmakers: they're in Settings (the cog icon), under Bookmakers. #### Using the filters well Market and period filters work in both apps. On the web, open the Markets and Periods panels next to Bookmakers on any tool page; in the desktop app, open Settings, then the Filter Markets and Filter Periods tabs. What you tick is hidden (1X2, handicaps, totals, corners, first-half lines...), which is how you turn the full firehose into a feed matched to the markets you actually bet. Check the filters first when a specific arb seems to be missing: it may sit in a market or period you've hidden. #### Mac and Linux The desktop app is Windows only. The web app runs fine in any browser on macOS and Linux; users who need the desktop-only features on a Mac run the app inside a Windows virtual machine (Parallels, VMware, VirtualBox). #### Where to go next The Navigation guide covers the Elite feature in depth, and the Back/Lay guide explains the exchange math the desktop app computes for you. ### [Surebet Navigation](https://www.oddstorm.com/guides/surebet-navigation) Updated 2026-10-17. Navigation is the Elite feature of the desktop app: one click on an arb's leg opens the bookmaker's site and navigates straight to that event's page, so you don't have to search for it by hand. Once the scanner hands you an arb, you still have to find the market at two bookmakers. This page explains what Navigation automates, how it sets Pro and Elite apart, and how to use it. #### What it does Finding the right event at a bookmaker by hand means: open the site, find the sport, the league, the match, the market. Navigation does that walk for you: the event page is open and waiting while the calculator still shows your stakes. It works per bookmaker, and not every bookmaker we scan has it. You still place the bet yourself, always: OddStorm never touches your bookmaker account. #### The only Pro/Elite difference Pro and Elite are identical in data: same scanning speed, same odds, same arbs at the same moment. Elite adds exactly one thing: Navigation. > **Note:** Navigation covers a limited number of bookmakers, and there's no published list. Before you choose Elite for it, ask support whether it works with your bookmakers, and pick the tier by how you work: the arbs are the same on both. #### Using it well - Stay signed in at your bookmakers in the same browser Navigation opens: if the event page opens while you're logged out, you have to sign in before you can bet. - Navigate the slow leg while you confirm the fast one. - If a bookmaker redesigns its site and a route misses, report it to support. > **Tip:** Navigation plus the odds-history check is the clean routine: verify the arb is alive, navigate both legs, place the fast leg, then the slow one. #### Where to go next The InPlay guide covers live arbing, and the desktop app guide covers everything else the Windows client adds. ### [Reading the calculator](https://www.oddstorm.com/guides/reading-the-calculator) Updated 2026-10-17. The calculator is where an arb becomes actual bets: type the stake for one leg and it works out the others, so every outcome returns the same amount. This guide reads every number on it, including the odds history that tells you whether to trust the arb at all. A broken lock usually doesn't die at the bookmaker: it dies inside this screen, in an edit or a rounding step that quietly unbalances the returns. Learn the four core numbers once and every arb reads the same way, PreMatch or InPlay; the odds history alone will save you from more bad placements than any other habit. #### The four numbers that matter Open any arb's calculator and read it in this order: - The percentage: the locked profit relative to your total stake. Change odds or a stake, then press Calculate (or Enter), and it's worked out again. - The stakes per leg: inversely proportional to each leg's odds. The round button next to a stake marks the leg you set yourself: type its stake, press Calculate, and the other legs are split around it (useful when a bookmaker caps your stake). The total is shown on the right; you don't type it. - The returns: every outcome should show the same return. If they differ after your edits, you no longer hold a lock. - The odds fields: editable, because YOUR job is to confirm the real odds at the bookmaker and correct any drift before betting. On an exchange leg, the Comm. field holds the commission taken off that leg's price; set it to the rate your account pays. #### Rounding without breaking the lock Never bet raw decimals at a soft bookmaker: mark its leg with the round button, type a natural number (20, 50, 100) and press Calculate; the other legs carry the decimals and the percentage stays the same. If you round those as well, watch the returns: it typically costs a few tenths of a percent, the insurance premium for account longevity. > **Tip:** Round the SOFT bookmaker's leg to the natural number and let the sharp leg carry the odd remainder: sharp books and exchanges do not care what your stakes look like. #### The odds history: seen and change Every leg shows how long ago its price was last confirmed ('Seen') and how long ago it last changed ('Change'), and the Odd History list shows each move with its difference. A leg seen seconds ago on a moving market is live; a leg unchanged for a long time on a busy market may be stale at the source. Read the history BEFORE placing: it decides which leg goes first (the moving one) and whether the arb is worth starting at all. It is also the evidence support will ask for if odds mismatch. #### The middles extras On middles and Polish middles the calculator grows three elements: the VALUE next to the percentage (the risk ratio explained in the middles guides), Return and Profit shown as Lost/Win pairs (what you lose outside the gap, what you win inside it), and the Condition line under the legs spelling out exactly which results land in the gap. Read the Condition every time: it is the contract of the bet. #### The free public calculator The fixed calculator on the website works without any subscription for every surebet type (1X2, handicaps, totals and the rest), not for middles: enter odds by hand, fix one stake and it balances the others the same way, rounded to 1, 5 or 10 if you like. Handy for checking a manual arb or teaching the math to a friend. #### Where to go next The middles guide explains the value math the middles calculator shows, and the beginner-mistakes guide covers the rounding discipline in the wider account-safety picture. ### [Payments and subscriptions](https://www.oddstorm.com/guides/payments-and-subscriptions) Updated 2026-10-20. An OddStorm plan is three choices: a tier (Pro, or Elite which adds Navigation), a product (PreMatch, InPlay, or both) and a duration (1, 6 or 12 months, plus a 1-week plan on Pro). This guide covers paying, renewing, stacking and the policies around all of it. None of it is complicated, but a few of the rules surprise people: subscriptions queue instead of overlapping, prices are identical for everyone with no codes to hunt, and pausing follows a precise formula. Knowing these three before you buy turns every billing decision into a thirty-second choice. #### How plans are built Pro and Elite are identical in scanning speed, odds and timing; Elite adds the Navigation feature of the desktop app. The product decides which feed you unlock: PreMatch, InPlay, or the combo. Longer durations price lower per month. Current prices always live on the pricing page: they are dynamic over time but the same for everyone and non-negotiable. There are no public discount codes: a promo code is personal and discounts only the first payment. Pro also comes as a 1-week plan: after 7 days it continues as the monthly plan unless you cancel auto-renew before then, and the money-back guarantee doesn't cover it. A '3-month' plan you may find referenced somewhere old no longer exists. #### Paying Checkout takes any card Stripe accepts for us (Visa, Mastercard, American Express, JCB and UnionPay, with Apple Pay and Google Pay too) and Skrill, which adds cards and the local payment methods it offers in your country. Someone else can pay for your plan: it goes to the account that's signed in on the pricing page, and the card or Skrill wallet can be theirs. Activation is immediate on successful payment; the receipt lands at your registration email, and every invoice stays available in your account. > **Note:** Arbers usually pay by the same Skrill wallet that runs their bookmaker bankroll: one money hub, one statement, no card surprises abroad. #### Managing a live subscription - Renewal: every plan renews automatically, by card or Skrill. Cancel auto-renew on your Subscription page and your access stays until the end of the period you've paid for. Nothing renews silently that the page does not show. - Stacking: buying a second subscription of the same tier and product while one runs QUEUES it: two 1-month Pro PreMatch subscriptions bought June 4 give access until August 4, never overlapping waste. Access you don't hold yet, such as Elite, or InPlay next to PreMatch, starts right away. While a plan renews automatically, the checkout won't start a second one of the same tier and product, so you're never charged twice for it. - Pausing: self-service from your Subscription page. One pause lasts up to one sixth of the billing period (monthly 5 days, 6-month 30, annual 60), with at most 60 paused days and 3 pauses per year. Paid days are preserved: resume by the date your Subscription page shows and your end date shifts by the paused time. A pause doesn't end by itself, and days past its limit aren't credited. Trials cannot be paused; Skrill-billed plans go through support. - Refunds: your first paid subscription carries a 7-day full money-back guarantee, filed from your Billing page; it doesn't cover renewals, later subscriptions, or promotional and discounted plans, including the 1-week plan. Outside it, refunds are discretionary: pro rata for unused time minus a 15 to 35 EUR processing fee. - Transfers and plan changes: support can transfer a subscription to another user; write from your registration email. To move to another plan, such as from Pro to Elite, cancel the renewal of your current subscription on your Subscription page first, then buy the new plan, so you're never charged for both. - Card renewals: to change the card we charge, use the link on your Subscription page; a new card replaces the old one for the next renewal. If a renewal fails, we email you and flag it in your account, and saving a working card takes the payment right away, so you don't need to buy the plan again. - Credit notes: when a refund goes through, a credit note appears on your Billing page next to the invoice it cancels, with that invoice's number and date, and it prints like any other document. #### The trial, precisely One 24-hour Elite PreMatch+InPlay trial per user, available Monday to Thursday. Create the free account first, then ask support at least 24 hours in advance from the registration email, naming the date that suits you. That is the entire procedure; there is nothing to buy first. #### Where to go next The getting-started guide tours the app the subscription unlocks, and the e-wallets guide sets up the Skrill hub that pays for both OddStorm and your bookmakers. ### [Your OddStorm account](https://www.oddstorm.com/guides/your-oddstorm-account) Updated 2026-10-20. Your plan, your payments and your settings each have a page in your oddstorm.com account. This tour shows what every page is for and the one or two things you'll actually do there. You can do most of it yourself: pause and resume a plan, file a money-back request, swap the card after a failed renewal, pick which emails reach you, ask for a bookmaker and write to us. #### Finding your account pages Sign in and click your username at the top right: the menu lists your account pages. Open one and the same list runs down the left side of the page (on a phone it turns into a row of tabs). #### Subscription: what you have and until when Under Your access, each plan shows when it started, the day it's active until and the days left. A plan bought while another was still running adds its time to that plan, so its Active until date moves later. Access we've booked to start later, such as a trial you asked for on a given day, shows as Scheduled and opens by itself on its start date. - Renewal: plans that renew on their own sit under Recurring subscriptions, with the next charge. Cancel stops the renewal, and you keep access until the end of the period you've paid for. Just paid and it isn't there? Press Refresh. - Card: when a plan renews by card, Change the card we charge opens the Card tab in Billing, where a new card replaces the old one for the next renewal. ##### Pause and resume Pause subscription stops your access and any upcoming charge right away and saves your remaining paid time. While you're paused, the page shows a resume-by date: resume by then and you get all of that time back. It also shows how long one pause can last and how many pause days you've used this year. > **Warning:** A pause doesn't end by itself, and days past the resume-by date aren't added back, so set a reminder the day you pause. Resuming takes one click. Trials can't be paused, and a plan that renews through Skrill is paused by our support team instead. #### Billing: invoices, credit notes and refunds Billing has two tabs. Invoices lists every payment with its number, date, product, amount and status, and View opens a printable copy. When a refund goes through, a credit note appears in the list, carrying the number and date of the invoice it cancels. ##### The refund button Your first paid subscription comes with a 7-day money-back guarantee: a full refund, no fee. For those 7 days a Request refund button sits next to that invoice. Press it, confirm, and the status turns to Refund requested while we review it; the money goes back the way you paid. Promotional and discounted plans, including the 1-week plan, aren't covered, and a refund ends the access that payment bought and stops its renewal. > **Note:** Outside the guarantee, refunds are at our discretion: contact support and we'll look at your case. ##### The Card tab and a failed renewal Card holds the card we charge for your next renewal. Your details go straight to our payment provider, and we never see or store them. If a card renewal fails, we email you and flag it in your account. Don't buy the plan again: add a working card on the Card tab and we retry the payment right away. Rather stop? The same tab lets you cancel that plan, and we won't try the failed payment again. #### Profile: time zone, emails and your details Profile holds your name and email (to change the email, contact support) and a Change password button. Three settings deserve a minute: - Time zone, under Preferences. Event times follow it, and a wrong zone is the usual reason a live match looks like it hasn't started. - Email preferences, also under Preferences. Switch off Your plan (reminders about your plan) or News and promotions; receipts, payment notices and sign-in links always arrive. Every optional email also has a one-click unsubscribe. - Country, under Billing. We use it for your invoices and VAT. > **Tip:** These three only change when you press Save changes at the bottom of the form. ##### Deleting your account Delete my account, in the last section of Profile, files a request. We delete the account within 30 days and email you when it's done, and until then you can cancel the request on the same page. We keep only what the law or a payment dispute needs (invoices, credit notes, payment records and our billing emails), plus a one-way fingerprint of your email and card that only checks whether a free trial was already used. > **Warning:** Paid time you still have ends with the account and isn't refunded. #### Notifications and History Notifications collects account, subscription and service updates from OddStorm, newest first with unread ones marked, and a Mark all as read button. Answers to your feedback land here too, and anything urgent also runs as a strip across the top of the site. History is your account's timeline: payments, access, trials, pauses and resumes, refund requests and the day auto-renew was cancelled. It starts in June 2026; older payments are on the Billing page. #### Bookmakers and Bookmaker requests Bookmakers is the account-page version of the Bookmakers panel in PreMatch and InPlay: saving here changes the ticks of your Default preset, which the panel shows while Default is in use. Named presets keep their own ticks, so change those in the panel. Each bookmaker has a PreMatch and an InPlay column with two boxes. Show displays it, Required shows only the arbs that include it. Bookmaker requests is where you ask for a bookmaker we don't cover yet and vote for the ones others asked for. Both need an active paid plan, though anyone signed in can read the list. Request a bookmaker needs only a name, and as you type it tells you if we already have that bookmaker (turn it on under Bookmakers) or if someone already asked for it (vote for theirs instead). Our team reviews each request before it opens for votes; until then yours shows as Awaiting review. Once a bookmaker moves to Added, its entry links to Bookmakers so you can switch it on. The five open requests with the most votes also appear under Most requested on the Supported Bookmakers page. #### Feedback: write to us Feedback is where you tell us what to fix, add or improve: pick a category, write it in your own words and press Send. If you've never paid for a plan, you get two short questions instead: what's missing, and what would make you subscribe. Everything you send stays under Your feedback, marked Received or Answered. When we answer, the reply shows under your entry and reaches you as a notice on the site and as an email. > **Tip:** Odds that don't match your bookmaker get sorted faster through support: send the four items from our guide to reporting wrong odds. #### Where to go next The payments and subscriptions guide explains how plans, renewal and stacking work, and the getting-started guide tours the feed your Bookmakers selection shapes. Got an idea none of these pages covers? That's exactly what Feedback is for. ### [Reporting wrong odds](https://www.oddstorm.com/guides/reporting-wrong-odds) Updated 2026-10-17. Sometimes the odds at your bookmaker do not match what OddStorm shows. Usually the explanation is timing or a clone domain; occasionally it is a real scanning issue we want to know about immediately. This is the two-minute check and the exact report that gets it fixed fastest. A vague 'your odds are wrong' email starts a round of questions; a report with the right four details lets us reproduce the case from your first message. The difference is knowing what support looks at first, so here's the checklist we wish every mismatch report followed. #### Before reporting: the two-minute check Three quick questions resolve most mismatches on the spot: - Timing: is the leg's 'seen' timestamp fresh? Odds move; a price seen 40 seconds ago on a live match may simply have moved on. That is the market, not a bug. - Domain: are you on the EXACT site we scan? A clone (another brand on the same platform) can shift or lag odds; a mirror of a bookmaker we cover shows that bookmaker's odds. 'Only I see different odds' is the classic clone symptom. - Market: same market, same period, same line? AH -0.75 at the book vs AH -1.0 in the app is a different market, not different odds. #### The report that gets fixed fast Still mismatched? Send support these four things, through the form on our Contact page or, with an active subscription, in Live Chat in the sidebar of the PreMatch and InPlay pages; together they let us reproduce the case: - Whether it is InPlay or PreMatch. - The FULL web address of the bookmaker you use (the exact domain, copied from the browser). - A screenshot of the arb calculator with the Odd History visible (the seen/change timestamps are the evidence). - A screenshot of the odd at your bookmaker, timestamped as close as possible to the first one. > **Tip:** Write from your registration email and paste the match name as text too: screenshots locate the odds, text lets us search the logs. #### What happens on our side We check the feed for that bookmaker and market at your timestamps. Clone-domain cases get an answer explaining which domain we scan; real discrepancies go straight to the parser team, and bookmakers with a genuine outage show as temporarily down on the Supported Bookmakers page until fixed. Either way you get an answer, not silence. #### Where to go next The clones guide explains the domain trap in depth, and why-surebets-exist covers the odds-history discipline that separates moved prices from wrong ones. ## FAQ: Getting started ### What is OddStorm? OddStorm is a sports arbitrage (surebet) service. It scans the odds of dozens of bookmakers in real time, detects arbitrage opportunities, and shows you exactly how much to stake on each outcome to lock in a profit whatever the result. (https://www.oddstorm.com/help/faq#q-what) ### Does OddStorm place bets automatically? No. OddStorm is not a betting bot. It finds the opportunities and calculates the stakes. Placing the bets is always up to you, and we never log into your bookmaker accounts. (https://www.oddstorm.com/help/faq#q-autobot) ### Web app or desktop app: what is the difference? The web app runs in any modern browser, phones and tablets included, and covers InPlay and PreMatch surebets, middles, odds comparison and the calculator. The desktop app is Windows only and adds the features that need deeper integration: Navigation and Back/Lay surebets. (https://www.oddstorm.com/help/faq#q-platforms) Download the desktop app: https://www.oddstorm.com/download/ ### Can I use OddStorm on a Mac? The web app works in any browser, macOS included. The desktop app is Windows only, so Mac users run it inside a Windows virtual machine. (https://www.oddstorm.com/help/faq#q-mac) ### Is there a free trial? Yes: a 24-hour Elite PreMatch+InPlay trial, available Monday to Thursday, one per user. Create a free account on our website, then contact support at least 24 hours in advance from the email you registered with and tell us which date suits you. (https://www.oddstorm.com/help/faq#q-trial) Create an account: https://www.oddstorm.com/register ### How do I contact support? Write to us through the form on our Contact page; we usually reply within a working day. With an active subscription you can also use Live Chat in the sidebar of the web app's PreMatch and InPlay pages, where our team answers. For questions about your account, use the email you registered with. (https://www.oddstorm.com/help/faq#q-contact) Contact us: https://www.oddstorm.com/contact ## FAQ: Arbitrage essentials ### Is arbitrage betting legal? Yes. Betting with regulated bookmakers is legal, and no law forbids covering all outcomes of an event across different bookmakers. Bookmakers dislike arbitrage and may limit very obvious arbers, but that is a business decision under their terms, not a legal issue. Gambling itself must be legal where you live, so check your local rules first. (https://www.oddstorm.com/help/faq#q-legal) ### How much money do I need to start? You can start small while you learn the flow, but the arithmetic starts working from roughly 1,000 to 2,000 EUR spread across your bookmakers. Arbitrage profit is a percentage of turnover, typically 1 to 3 percent per arb, so your bankroll determines what the same work actually earns. (https://www.oddstorm.com/help/faq#q-bankroll) ### How many bookmaker accounts do I need? Around ten is a practical start: enough that arbs regularly appear between books you hold, few enough to manage deposits and verification. Prioritize the sharp anchors (Pinnacle, exchanges) plus the biggest soft bookmakers available in your country, then grow the list over time. (https://www.oddstorm.com/help/faq#q-howmanybooks) ### How much can I realistically earn? Active arbers commonly target around 10 to 20 percent of their bankroll per month. The driver is turnover: each arb locks in a small percentage, so results scale with how many arbs you place and how much you can stake. Anyone promising fixed income or spectacular returns is not being honest with you. (https://www.oddstorm.com/help/faq#q-profit) ### What are the most common beginner mistakes? Chasing suspiciously high arbs (often bookmaker errors that get voided), placing one leg and hesitating on the other, ignoring stake rounding so your bets scream arbitrage, and starting with real money before the routine is automatic. Do a few paper trades first: pick an arb, write down the stakes, watch both legs settle. (https://www.oddstorm.com/help/faq#q-mistakes) ### Why do odds move and how fast do I need to act? Odds move constantly as bookmakers react to news and incoming bets. An arbitrage is a temporary disagreement between two books, so it can vanish in seconds, especially InPlay. Place the leg most likely to move first (usually the sharp bookmaker), then complete the other leg immediately. (https://www.oddstorm.com/help/faq#q-whyoddsmove) ### Why should I avoid arbs above 10 percent? A very high percentage is usually a bookmaker mistake, a so-called palpable error, and bookmaker terms allow them to void such bets. If one leg gets voided you are left holding an open bet, not an arbitrage. Steady profit lives in the 1 to 5 percent range. (https://www.oddstorm.com/help/faq#q-palps) ### InPlay or PreMatch arbing: which should I choose? PreMatch is calmer: you have more time to place both legs, but arbs are smaller and appear more slowly. InPlay produces more and bigger arbs because odds move fast, but you must act in seconds and mistakes cost more. Most arbers start PreMatch and add InPlay once the routine is automatic. (https://www.oddstorm.com/help/faq#q-liveprematch) ### How do I avoid getting limited by bookmakers? Behave like a recreational bettor: round your stakes to 20, 50 or 100, skip suspiciously high arbs and obvious errors, withdraw rarely and in round amounts, and occasionally bet popular markets. Sharp bookmakers and exchanges (Pinnacle, Betfair) welcome winners and do not limit accounts. (https://www.oddstorm.com/help/faq#q-limitation) ### Do I owe taxes on arbitrage profit? That depends entirely on your country: some tax gambling winnings, many do not, and a few tax bookmaker turnover instead. We cannot give tax advice; check your local rules or ask an accountant. (https://www.oddstorm.com/help/faq#q-taxes) ## FAQ: Plans and billing ### What is the difference between Pro and Elite? The only difference is the Navigation feature: in the desktop app it opens the bookmaker at the right event for you, on the bookmakers it supports (ask support about yours). Scanning speed, odds and timing are identical on both tiers. (https://www.oddstorm.com/help/faq#q-proelite) ### What plans are available? A plan is a tier (Pro or Elite), a product (PreMatch, InPlay, or PreMatch+InPlay) and a duration (1, 6 or 12 months). Pro also comes as a 1-week plan: after 7 days it continues as the monthly plan unless you cancel auto-renew before then, and the money-back guarantee doesn't cover it. There are no 3-month plans. (https://www.oddstorm.com/help/faq#q-available) See current prices: https://www.oddstorm.com/prices ### How much does it cost? Current prices are always on the pricing page and can change over time. They're the same for everyone and non-negotiable. There are no public discount codes: a promo code is personal and discounts only the first payment. (https://www.oddstorm.com/help/faq#q-cost) See current prices: https://www.oddstorm.com/prices ### Which payment methods do you accept? Cards and Skrill. Pay with any card that Stripe, our card processor, accepts for us (Visa, Mastercard, American Express, JCB and UnionPay), Apple Pay and Google Pay included, in the secure form on the pricing page. Or choose Skrill and pay from your Skrill wallet, by card or with the local methods Skrill offers in your country, on Skrill's own checkout. We don't take PayPal. (https://www.oddstorm.com/help/faq#q-payment) See current prices: https://www.oddstorm.com/prices ### Do subscriptions renew automatically? Yes. Every plan renews automatically at the end of its period, by card or Skrill, and the 1-week plan continues as the monthly plan. You can cancel auto-renew at any time on your Subscription page, and your access stays until the end of the period you've paid for. (https://www.oddstorm.com/help/faq#q-renew) ### What happens if I buy a second subscription? Access to the same tier and product stacks: a second plan starts when the first one ends, so two 1-month Pro PreMatch plans bought on June 4 give you access until August 4. Access you don't hold yet, such as Elite, or InPlay next to PreMatch, starts right away. While a plan renews automatically, the checkout won't sell you the same tier and product again, so you're never charged twice for it: turn auto-renew off first if you want to queue one. (https://www.oddstorm.com/help/faq#q-stack) ### Can I get a refund? Your first paid subscription has a 7-day money-back guarantee: within 7 days of the first charge you get a full refund, no fee, filed with one click from your Billing page. It doesn't cover renewal payments, any subscription after your first, or promotional and discounted plans, including the 1-week plan. Outside that window refunds are discretionary: a pro rata amount for the unused time minus a processing fee of 15 to 35 EUR, decided case by case. Pausing your subscription (paid days preserved) or transferring it to another user is often the better deal. (https://www.oddstorm.com/help/faq#q-refund) Terms and Conditions: https://www.oddstorm.com/terms ### Can I pause my subscription? Yes, self-service from your Subscription page. One pause can last up to one sixth of your billing period (5 days on a monthly plan, 30 on a 6-month, 60 on an annual), with at most 60 paused days and 3 pauses per rolling year. While paused your access stops and paid days are preserved: resume by the date your Subscription page shows and your end date shifts by the paused time. A pause doesn't end by itself, and days past its limit aren't credited. Free trials can't be paused, and Skrill-billed subscriptions need our support team to arrange it. (https://www.oddstorm.com/help/faq#q-pause) Open your Subscription page: https://www.oddstorm.com/user/mysubscription ### Can I transfer my subscription to someone else? Yes. Contact support from the email you registered with and we will arrange the transfer. (https://www.oddstorm.com/help/faq#q-transfer) Contact support: https://www.oddstorm.com/contact ### Why do I see profits capped at 0.50% and hidden names? That is the free preview. Without an active subscription profits are capped at 0.50% and event and league names stay hidden. Everything unlocks the moment a subscription or trial is active. (https://www.oddstorm.com/help/faq#q-cap) ### I have a plan. Why are names hidden on the PreMatch or InPlay pages? Each product unlocks its own pages. An InPlay plan unlocks the InPlay surebets and middles, a PreMatch plan the PreMatch ones, and PreMatch+InPlay unlocks both. On the pages of a product you don't hold you get the free preview: event names hidden, surebet profits capped at 0.50%, and a single result on the Middles and Polish Middles pages. (https://www.oddstorm.com/help/faq#q-oneproduct) ### How do I delete my account? Sign in, open your Profile and choose Delete account. We delete it within 30 days and email you when it's done, and you can cancel the request on the same page until then. Paid time you still have ends with the account and isn't refunded. We keep only what the law or a payment dispute needs (invoices, credit notes, payment records and our billing emails), plus a one-way fingerprint of your email and card that only checks whether a free trial was already used. (https://www.oddstorm.com/help/faq#q-deleteaccount) Open your Profile: https://www.oddstorm.com/user/myprofile ## FAQ: Using OddStorm ### Which bookmakers do you support? The live list, including PreMatch and InPlay availability, is on our Supported Bookmakers page; sign in with a free account to open it. In the web app, open the Bookmakers panel on the left in PreMatch or InPlay to see and customize your own selection; in the desktop app it's Settings (the cog icon), then Bookmakers. Missing one? With an active paid plan you can request it, and vote on other requests, on the Bookmaker requests page in your account. (https://www.oddstorm.com/help/faq#q-bookmakers) Supported bookmakers: https://www.oddstorm.com/bookmakers ### How fast does OddStorm find surebets? InPlay surebets reach you within 1 to 3 seconds of the odds appearing. PreMatch odds are scanned every 15 to 180 seconds depending on the bookmaker: sharp bookmakers the most often, to catch their moves fast, and soft ones more slowly. The speed is the same on Pro and Elite. (https://www.oddstorm.com/help/faq#q-speed) ### Can I filter by market or period (1X2, Over/Under, corners)? Yes. On any tool page open the Markets and Periods panels next to Bookmakers: tick what you don't want and those arbitrages are hidden, for example corners or first-half lines. In the desktop app it's Settings, then the Filter Markets and Filter Periods tabs. (https://www.oddstorm.com/help/faq#q-markets) Download the desktop app: https://www.oddstorm.com/download/ ### What is Navigation? An Elite feature of the desktop app. One click on a leg of the arbitrage opens the bookmaker's site at that event's page, so you don't have to search for it by hand. It works with some of the bookmakers we scan, not all of them, and there's no published list: ask support about your bookmakers before you choose Elite for it. (https://www.oddstorm.com/help/faq#q-navigation) ### How do I access Back/Lay surebets? Back/Lay surebets (a bookmaker against a betting exchange) are available in the desktop app only. (https://www.oddstorm.com/help/faq#q-backlay) Download the desktop app: https://www.oddstorm.com/download/ ### What does a red arbitrage mean? In the web app it depends on where you see it. A red percentage in the PreMatch list means the match starts within 15 minutes, and the arb is still live. Red boxes at the top of the calculator mean the arb you opened has left the list: it no longer exists at those odds. (https://www.oddstorm.com/help/faq#q-colors) ### Do you offer value bets? Every surebet has value on its soft side. If value betting is your strategy, use the filters and place only the soft side of the arbitrage. (https://www.oddstorm.com/help/faq#q-valuebets) ## FAQ: Troubleshooting ### The odds do not match my bookmaker. What should I send you? Four things: whether it is InPlay or PreMatch, the full web address of the bookmaker you use, a screenshot of the arb calculator with the Odd History visible, and a screenshot of the odd at your bookmaker. Many bookmakers run clone sites with slightly different odds, so the exact domain matters. (https://www.oddstorm.com/help/faq#q-wrongodds) Contact support: https://www.oddstorm.com/contact ### Another service shows a surebet that OddStorm doesn't. Why? Usually a setting hides it. Check that both bookmakers are ticked in the Bookmakers panel, that the market and period aren't hidden in the Markets and Periods panels, and that the minimum liquidity you set for an exchange isn't filtering it out. Reset to defaults in each panel undoes your changes. We also don't scan every market at every bookmaker. (https://www.oddstorm.com/help/faq#q-missingarb) Read the filters guide: https://www.oddstorm.com/guides/web-app-filters-and-presets ### I have a plan, but my surebet list in the web app is empty. Why? Usually a sidebar setting hides the surebets, and it follows you: your choices there are saved to your account, so another browser, another device or a cleared cache keeps them. Click Reset to defaults in the Settings, Bookmakers, Markets and Periods panels. Still empty? Send support a screenshot of the whole page with the sidebar. (https://www.oddstorm.com/help/faq#q-emptylist) Read the filters guide: https://www.oddstorm.com/guides/web-app-filters-and-presets ### The desktop app won't sign in or shows no bookmakers. What can I do? First check that you run the current version: the app doesn't update itself, it tells you at sign-in when a new one is out, and the latest is on the Download page. Bookmakers are chosen in Settings (the cog icon), then Bookmakers. Still stuck? Send support your username, the app version and a screenshot. (https://www.oddstorm.com/help/faq#q-desktopapp) Download the desktop app: https://www.oddstorm.com/download/ ### A bookmaker stopped updating. Is it down? Check the live status on the Supported Bookmakers page: temporarily down bookmakers are marked there. Our team sees the same signal and works on fixes with top priority. (https://www.oddstorm.com/help/faq#q-bookiedown) Supported bookmakers: https://www.oddstorm.com/bookmakers ### Which bookmakers are legal in my country? Licensing differs per country and we cannot verify it for you. Please check with your local gambling regulator which of the supported bookmakers are licensed to operate in your region. (https://www.oddstorm.com/help/faq#q-licensing) ### Do you support brokers (BetInAsia, MollyBet)? No. OddStorm does not work with brokers in general; we scan the bookmakers on the supported list directly. (https://www.oddstorm.com/help/faq#q-brokers) ### Do you offer an odds API? Odds data via API is provided by our sister service OddFeeds. Contact them directly for access and pricing.
