Does its posted price hold?
Of 128 BetRivers prices Omenizer flagged as market-beating in the last 90 days, 40% were still there or better when we looked again; 60% had moved against the bettor and 0% had the market pulled. Measured only on prices we flagged as outliers — the ones most likely to be corrected — so read it against other books here, not as a share of BetRivers's whole board.

In the last 90 days, BetRivers posted the board-leading price on 128 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 7.82% margin means that, on a typical BetRivers market, prices pay out 7.82% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.
