Does its posted price hold?
Of 151 betparx prices Omenizer flagged as market-beating in the last 90 days, 41% were still there or better when we looked again; 59% had moved against the bettor and 1% 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 betparx's whole board.

Who runs betparx

Operator: Bally / betPARX. (reported — verification in progress) Sibling brands under the same operator: Bally Bet.

Availability: licensed in US. (reported — verification in progress)

In the last 90 days, betparx posted the board-leading price on 151 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 7.22% margin means that, on a typical betparx market, prices pay out 7.22% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.
