In the last 90 days, Coolbet posted the board-leading price on 1,026 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 6.92% margin means that, on a typical Coolbet market, prices pay out 6.92% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.
