A 10,000-path Monte Carlo simulation over your own trade history, at whatever risk-per-trade level you're considering, before you pay for a challenge.

Prop Passer runs your own trade history through a 10,000-path Monte Carlo simulation to estimate your probability of passing a challenge, at whatever risk-per-trade level you're considering, before you risk an account fee.

Pass probability by risk level

Move the risk-per-trade slider and watch pass and bust probability update together, higher risk passes faster but busts more often.

Recommended risk

A suggested risk-per-trade level, from your own win rate and average win/loss.

Reality check

Your own trades replayed once, in the order they happened, at the selected risk, ground truth for that one sequence, next to the simulated odds.

Kelly & optimal f

Growth-optimal risk references from your history. Both ignore drawdown limits and sit well above any prop-safe level, shown for reference, not as a recommendation.

A simulation, not a guarantee

Prop Passer estimates odds from your past trades, it can't see future trades, and a run of bad luck (or a change in how you trade) can beat any probability. It's built to size risk sensibly, not to promise a pass.
