Read in Chinese →What win rate would break even?
Assume a loss forfeits the full stake, a win earns the net profit entered below, and a fixed extra fee applies each time. This explains the mathematics; it does not estimate your actual win rate.

Formula: (stake + fee) ÷ (stake + net winning profit). Actual products may use different loss, fee and refund structures.
