🧮 How We Calculate

Parlay: Convert each American odds to decimal, multiply them, then multiply by stake.

Hedge: Hedge stake = (original stake × original decimal odds) / hedge decimal odds. Guaranteed profit = (original stake × original odds) - total stakes.

Arbitrage: Arb % = sum of (1 / decimal odds). If < 100%, arbitrage exists. Stakes = (total wager × inverse odds) / arb %.

We use precise formulas and round to two decimals.
