Finding arbs is easy. Keeping your accounts is the hard part.

What it is: When professional bettors ("sharps") place large bets, the odds move fast. That's called a steam move.

Why it matters: If you bet into a line that's already moving, the arb can vanish before you get both sides down. Steam detection warns you in real time — either to jump on it fast, or to stay away.

What it is: After you place a bet, the odds keep moving until the game starts. The final odds before kickoff are the "closing line." CLV measures whether you got better odds than that.

Why it matters (performance): Consistently beating the closing line is the #1 predictor of long-term profit. If your CLV is positive, you're a winning bettor — not just lucky.

Why it matters (stealth): CLV is exactly what sportsbooks use to identify sharp bettors. ArbEdge tracks CLV per book and feeds it into your heat scores — so if you're winning too visibly at one book, the bot warns you to cool off before you get flagged.

What it is: Every sportsbook watches for winning players. A "heat score" tracks how suspicious your activity looks at each book — based on win rate, bet frequency, and volume.

Why it matters: If your heat gets too high, the book will limit or ban you. ArbEdge tells you when to take a break at a specific book before they flag your account. This keeps you profitable for longer.

What it is: Sportsbooks share data through monitoring networks. If you bet the same game at 3+ books within a few hours, they can connect the dots and identify you as an arber.

Why it matters: ArbEdge monitors your patterns across all books and warns you when your activity starts looking correlated. It tells you which books to space out so you don't get flagged.

What it is: Bots bet in predictable patterns — same timing, round stakes, no breaks. Sportsbooks look for exactly this. Stealth mode randomizes your bet timing, stake amounts, and session length.

Why it matters: Your activity looks like a casual bettor instead of a bot. This extends how long you can bet at each book before they catch on.

What it is: A math formula that calculates the optimal bet size based on your edge and bankroll. Every alert comes with a suggested stake sized to your bankroll — no guesswork.

Why half-Kelly is the default: Arbitrage has a guaranteed edge — you know the exact profit before you bet. Half-Kelly captures ~75% of the growth rate of full Kelly while leaving room for execution risk (line moves, voided legs). It's the sweet spot.

The four presets (example: 3% arb on a $1,000 bankroll):
• Quarter Kelly (25%) — $12 stake. Ultra-conservative. Best for value bets where edge is estimated.
• Third Kelly (33%) — $16 stake. Middle ground for newer bettors building confidence.
• Half Kelly (50%) — DEFAULT — $24 stake. Optimal for arbs with a guaranteed edge.
• Full Kelly (100%) — $48 stake. Maximum growth, but aggressive. Experienced bettors only.

Customize via /settings:
/settings kelly half — preset (quarter, third, half, full)
/settings kelly 0.40 — any custom fraction
Your choice applies to every alert instantly. No restart needed. All Kelly calculations are capped at 20% of your bankroll — so even full Kelly can't overexpose you on a single bet.

What it is: You sign up for your own odds-api.io account and bring your own API key. ArbEdge uses your key to fetch odds data directly.

Why it matters: Maximum speed — data comes straight to you, not through a middleman. Maximum privacy — we never see your bets, your books, or your strategy. You own your data.

What it is: REST polling checks for new odds every 15 seconds. WebSocket (available on BYOK) keeps a live connection open — odds are pushed to you the instant they change.

Why it matters: Arbs can close in seconds. WebSocket gives you the fastest possible alerts. REST is still fast enough for most arbs, but WebSocket is for users who want every possible timing edge.

What it is: Scans player prop markets (points, rebounds, assists, passing yards, strikeouts, etc.) across all your books and detects arb opportunities. For example: LeBron Over 25.5 Points at +105 on Bovada vs Under 26.5 Points at -102 on FanDuel.

Why it matters: Props have softer lines than mainline markets — books set them with less precision, which means more frequent arb windows. Props also have cross-point middles: if the Over/Under points differ, there's a range where both sides win (e.g., if LeBron scores exactly 26, both bets cash).

How to enable: /settings toggle props on — off by default since it uses additional API calls. Set your minimum prop arb % with /settings minprop 1.0.

What it is: A "middle" happens when two books offer different spread or total lines for the same game. You bet both sides and there's a window of scores where both bets win. Example: Over 220.5 at Book A + Under 223.5 at Book B — if the game lands at 221, 222, or 223, both bets cash.

Why it matters: Every middle is guaranteed-profit arb PLUS a bonus window where you win both sides. ArbEdge detects middles automatically and shows the exact point range in your alert. Works on both regular spread/total arbs and player prop arbs. Toggle with /settings toggle middles on.

What it is: Scans odds on games that are already in progress. In-play lines move constantly as the game unfolds, which creates arb opportunities that don't exist pre-game.

Why it matters: Live arbs tend to have bigger edges (2-5%+) but close in seconds, not minutes. This is an opt-in feature — disabled by default — because it requires fast execution and comfort with rapid line changes. Enable it via /settings toggle live on when you're ready. Best paired with WebSocket for minimum latency.

Bring Your Own Key. You sign up for your own odds-api.io account and get your own API key (REST or WebSocket). This gives you the fastest possible data since requests come directly from your key. We never see your bets, your books, or your strategy. ArbEdge is the alert layer on top of your data. Don't want to manage your own key? The Pro plan is $30/mo beta — we handle the data, you just bet.

Two options: BYOK ($10/mo beta) — bring your own odds-api.io REST or WebSocket key. Your API plan controls your bookmaker count. Total cost is roughly $110-240/mo depending on your API plan. Full control, maximum privacy. Pro ($30/mo beta) — we handle the data, no API key needed. Just subscribe and bet. All features included on both plans — no paywalled tiers. Beta pricing is limited to 50 spots. Once full, BYOK goes to $20/mo and Pro to $60/mo. If you're in the first 50, your rate is locked for life.

1) Steam detection — spots sharp money moving lines before they correct. 2) CLV tracking — measures if you're beating the closing line per book. 3) Heat scores — 0-100 rating per book tracking how suspicious your activity looks. 4) Smart cooldowns — automated break recommendations when heat rises. 5) Cross-book correlation — detects when your betting patterns across books become linkable. 6) Stealth mode — randomizes timing, stakes, and sessions to look recreational. 7) Alert scoring — ML rates every arb 0-100 based on 13 features. 8) EEV (Estimated Execution Value) — effective $/hr so you know if a bet is worth your time. 9) Smart scan priority — ML learns which sports and markets produce the best arbs. No other scanner has any of these.

Yes — 4 of our 10 launch books are offshore: Bovada, BetOnline.ag, MyBookie, and BookMaker.eu. These are where arbs originate most often because they're slower to move lines than the regulated books. OddsJam skips offshore entirely. As we expand based on community votes, the API supports 250+ books across US, UK, EU, Australia, crypto, and prediction markets — including cross-region arbs (like Pinnacle EU vs Bovada US) where the biggest edges hide. BYOK users can access any supported book immediately with their own API key.

Every scanner finds arbs — that's the easy part. The hard part is lasting at the books long enough to profit. OddsJam ($200-999/mo) has arbs, +EV, middles, and props — but no offshore coverage, no account protection, and no AI features. Bet Hero covers 230+ international books but has zero intelligence features — no steam detection, no CLV, no heat scores, no stealth. BetBurger is similar: wide coverage, no protection. ArbEdge is the only scanner with 9 AI engines designed to extend your account lifespan. We launch with 10 US books (6 regulated + 4 offshore including Bovada and BetOnline that OddsJam skips entirely), with the community voting on which books get added next from the 250+ the API supports. Plus a prop consensus value finder that none of them offer. Account protection at a fraction of the price.

All major US sports: NBA, NCAAB, NHL, NFL, MLB, UFC/MMA, and more. At launch we scan 10 US books across these sports — the ones where arb and value bet opportunities are most frequent. As we expand coverage based on community votes, international sports like soccer and tennis become arb goldmines since different regions price differently. Coverage adjusts by season so you're not wasting scans on offseason sports.

Free tier: alerts are checked every 3 minutes and posted to Discord. BYOK and Pro: checked every 15 seconds and pushed to your Telegram — fast enough to catch most arbs before they close. BYOK users with a WebSocket key get near-instant alerts the moment a line moves. WebSocket support for Pro is coming soon. The underlying data from odds-api.io updates roughly every 1 second, so the bottleneck is our scan interval, not the data source.

It depends on your API plan. Starter (5 books): $500–$1,000 — enough to spread $100–200 per book. Catches fewer arbs but lower API cost, great for learning. Growth (10 books): $1,000–$3,000 — the sweet spot, 2x the arb opportunities. Most users start here. Pro (15 books): $2,500–$5,000+ — maximum book coverage and best ROI at scale. The bot uses Kelly sizing to calculate optimal stakes on every alert, so you never overexpose. If you have $500, start with Starter. If you have $2K+, Growth pays for itself fast. You can always scale up later.

WebSocket access on odds-api.io doubles the price of any API plan — so Starter goes from ~$125/mo to ~$250/mo with WebSocket. BYOK users can use either REST or WebSocket keys — both are fully supported with all features. If you don't need sub-second speed, REST polling at 15-second intervals is plenty fast for most arbs. WebSocket is for users who want every possible edge on timing. Pro plan will add WebSocket support soon — at launch it uses REST polling.
