Strip the vig from a two-way market to get the true fair odds, then measure the expected value of the price you can actually bet.
Removing the sportsbook's margin (vig) from a market. We convert each side's odds to implied probability, then rescale so they sum to 100% — the result is the fair, no-vig probability.
EV% = (your decimal odds × fair probability) − 1. A positive number means the price you're getting is better than the true odds — a long-run edge.
It's the best cheap estimate. Sharper books and a consensus across many books give a more reliable fair line — which is what our engine computes.
