Prop Firm Challenge Risk Calculator

Estimate whether a trading strategy is likely to pass a funded account challenge before risking money on an evaluation. Enter the account rules, add your strategy assumptions, then run single-path and batch Monte Carlo simulations. The chart separates the max drawdown line from the daily-loss line so static drawdown does not appear to trail when the trailing toggle is off.

Estimated pass rate — Run a batch simulation to calculate this.
