About Kelly Criterion
Kelly formula: f = (b×p − q) / b, where b = net odds (odds−1), p = win probability, q = 1−p.
Full Kelly targets long-run growth under accurate, stable probability estimates. Quarter-Kelly (25%) uses a quarter of that stake to reduce exposure; losses and drawdowns remain possible.
