🐘 Stock Market Elephant/ EV Calculator

Prop Firm EV Calculator

Runs a trade-level Monte Carlo of your strategy (win rate + reward:risk) through the evaluation, the funded account, and a full bankroll ladder — 3,000 account simulations plus 1,500 ladder simulations, entirely in your browser. Defaults model a $150K one-step eval with an EOD-trailing drawdown; every rule is editable, so match it to any firm. Verify rules against the firm's own site — they change constantly.
