📐 How arbitrage works: Convert American odds to decimal: positive = (odds/100)+1; negative = (100/|odds|)+1. Sum of reciprocals = 1/decimal1 + 1/decimal2 + ... If < 1, an arbitrage exists. Stake for outcome = totalStake × (1/decimal) / sumOfReciprocals. Payout = stake × decimal (same for all outcomes). Profit = payout - totalStake.

3. Click "Calculate Arbitrage"

4. Adjust as needed
If no arbitrage is found, try different odds or stakes.
