How we calculate arbitrage

We read the latest moneyline prices per sportsbook. For each match we search across books for the best cross-book pair: the highest home price and the highest away price that together form a surebet.

• • Condition (2-way): 1/O_home + 1/O_away < 1
• • Condition (3-way): 1/O_home + 1/O_draw + 1/O_away < 1
• • Sum of inverses: s = Σ(1/O)
• • ROI: ROI = 1/s - 1
• • Optimal stake split for total stake T:
  Home: T × (1/O_home) / s · Draw: T × (1/O_draw) / s · Away: T × (1/O_away) / s

Notes: We evaluate 2-outcome and 3-outcome (1X2) markets where available. Quotes are taken as-is and may be subject to change, limits, or suspension by the sportsbook. Ensure prices are still available before placing bets.
