Who runs Betfair Exchange (AU)
Availability: licensed in AU.
The margin is the bookmaker's built-in fee: the amount by which its implied probabilities exceed 100%. A 4.14% margin means that, on a typical Betfair Exchange (AU) market, prices pay out 4.14% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.
