Arbitrage (surebet)
Arbitrage, or a surebet, is when prices across books or the exchange let you cover every outcome for a guaranteed-in-theory margin.
An arbitrage exists when the combined prices on all outcomes imply less than 100% probability, so backing each at the right stake locks a margin regardless of the result. In practice they are rare, small and short-lived.
Detecting arbitrage needs wide, normalised coverage and the exchange lay side. OddsRelay supplies that; your scanner applies its own thresholds and staking.
Real surebets are rare and short-lived, prices move and accounts get restricted — the data surfaces opportunities, it never implies guaranteed profit.
