Calc Edge

+EV / fair-line / no-vig calculator. FREE. iter-75 deploy / #456.

Two modes:

  1. Pass true_prob directly: returns EV vs your stated win prob.
  2. Pass sharp_over_odds + sharp_under_odds: derives the no-vig fair probability from the two-sided sharp market, then computes EV against that fair line. This is the canonical EV-scan formula.

edge_pct is in percent (positive = +EV).
