In the last 90 days, Desert Diamond posted the board-leading price on 153 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 7.83% margin means that, on a typical Desert Diamond market, prices pay out 7.83% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.
