In the last 90 days, BetOnline posted the board-leading price on 721 signals flagged by Omenizer's detection engine.
The margin is the bookmaker's built-in fee: the amount by which its implied probabilities exceed 100%. A 5.69% margin means that, on a typical BetOnline market, prices pay out 5.69% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.
