ODDSFLOOR

A free arbitrage betting tool that nets the fees before it shows you the arb

Short answer: OddsFloor scans 55+ sportsbooks and betting exchanges for arbitrage and low holds. Where a leg sits on an exchange, the exchange's cut of winnings is taken out before the arb is shown, so a number that only works before fees never makes the list. Free with an account, no card.

What an arb is, and why most tools overstate them

Two books disagree. One prices a side high, the other prices the opposite side high, and the two add up to less than 100% after the margin. Bet both in the right proportion and you lock a small return whichever side wins.

The overstated part is the exchange leg. Exchanges charge a cut of winnings. An arb that's +1.2% before that cut can be negative after it. Many finders print the gross number. OddsFloor prints the net one, and tells you the cut it took out.

What the tool does

• Arbs across 55+ books and exchanges, rescanned as prices move.
• Fees netted. Each exchange's cut of winnings comes out before the arb shows. The row says what the cut was.
• Low holds. Two-sided positions that lose a little whichever way they go, listed next to the arbs for people working promo credit or bonus bets.
• Only your books. Pick the books you hold. A two-leg arb only shows if you can bet both legs.
• The stake split, done. Enter the total and the tool splits it across the legs.
• Links to each leg, built from the live price where the book supports it.

What it doesn't do

• It doesn't hold an arb open for you. One book usually moves within seconds. If you can't place both legs fast, treat the row as information, not a plan.
• It doesn't stop books from limiting you. Books notice arb patterns. Many limit accounts that take them. That's the real cost of this strategy.
• It doesn't place bets. Each leg links to the book. Check both prices there, and place the harder leg first.
• It can't see a book's max bet. A great arb at a $20 limit is a $0.24 arb.

FAQ

What is an arbitrage bet?

Two prices on opposite sides of the same market, at different books, that add up to less than 100% after the margin. Bet both in the right proportion and you lock a small return whichever side wins. The catch is that arbs are small, they close fast, and books limit accounts that take them.

Is there a free arbitrage betting tool?

Yes. OddsFloor scans 55+ sportsbooks and betting exchanges for arbs and low holds, free with an account and no card. Where one leg is on an exchange, the exchange's cut of winnings is netted before the arb is shown, so a number that only works before fees never appears.

What is a low hold?

The same shape as an arb, but the two prices add up to slightly more than 100%. You lose a little whichever side wins. People use low holds to turn promo credit or bonus bets into cash at a known small cost. The tool lists them next to the arbs.

Why did an arb vanish before I could bet it?

Because one book moved. An arb exists only while two books disagree, and one of them usually fixes that within seconds. Any read of a price can lag the book. Check both prices at the books before you place either leg, and place the harder leg first.
