How Prop Firm Challenges Work
Prop firm challenges require traders to hit a profit target (typically 8-10%) within a time limit while staying within strict drawdown limits. Most firms enforce both a daily drawdown limit (usually 5%) and a total drawdown limit (usually 10%).
This simulator runs 1,000 randomized trading scenarios using your actual statistics to estimate your pass rate. The equity curve visualization shows sample paths — green lines that reach the target and red lines that hit drawdown limits.
The key to passing is combining a positive expected value with conservative position sizing. Even a highly profitable strategy can fail the challenge if risk per trade is too high relative to the drawdown limits.

Who Is This For?
Traders preparing for prop firm challenges (FTMO, MyFundedFX, etc.) who want to estimate their probability of passing based on their trading statistics. Helps set realistic expectations before paying for a challenge.
Worked Example
$100K account, 8% profit target, 10% max drawdown, 5% daily loss limit.
Win rate 50%, avg win $500, avg loss $300, 3 trades/day.
Simulation result: ~68% pass rate, average 12 days to pass.
Assumptions & Edge Cases
- Simplified model — does not account for trading day limits, weekend gaps, or news events.
- Assumes consistent trade frequency and execution.
- Daily loss limit check is approximate.
- Results are probabilistic, not guaranteed.
Frequently Asked Questions
A prop firm challenge requires you to hit a profit target (usually 8-10%) while staying within daily and maximum drawdown limits. Pass the challenge and you trade the firm's capital.
Most firms enforce a daily drawdown limit (4-5% of starting balance) and a maximum overall drawdown (8-12%). Breaching either instantly fails the challenge.
Yes. Set your challenge rules, starting balance, and profit target, then simulate trades to see if your strategy can pass without breaching drawdown limits.
