About Prop Firm Calc

Prop Firm Calc runs 10,000+ Monte Carlo simulations of a trader's win rate, average risk-to-reward ratio, and trade frequency against the published evaluation rules of major proprietary trading firms.

The goal is to give traders a realistic, quantitative pass-probability estimate before they pay for an evaluation, instead of relying on flat comparison tables that ignore the interaction between drawdown type, profit target, and time limits.
