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.
