Only 4-10% of traders pass prop firm evaluations on their first attempt. Our challenge simulator runs Monte Carlo simulations of your trading strategy to calculate your probability of passing, average days to completion, and risk of ruin — before you spend money on an evaluation.

Ready to optimize your prop firm journey? Our Monte Carlo simulator guides you to maximize your success chances. Use it today to validate your strategy and pass your challenge with confidence.
Our challenge simulator runs 10,000 randomized simulations of your trading strategy against prop firm rules. Each simulation shuffles your win/loss sequence differently — because in real trading, the ORDER of wins and losses matters as much as the overall win rate.
A trader with 60% win rate might pass easily in one sequence (wins clustered at the start) but fail in another (losses clustered at the start, triggering drawdown). Monte Carlo simulation tests ALL possible sequences to give you a realistic probability of passing.
This is more reliable than backtesting because backtests show you ONE specific sequence of trades. Monte Carlo shows you EVERY possible outcome — including worst-case scenarios that backtests miss.
Pass Probability is the percentage of simulations where you reached the profit target without hitting the drawdown limit. Aim for >60% — anything below 50% means your strategy needs adjustment before you risk real money on an evaluation.
Average Days to Pass gives you a realistic timeline. If it shows 30+ days, consider whether the monthly subscription cost (for firms like Topstep) is worth it, or if a one-time payment firm (like Apex) would be more cost-effective.
Risk of Ruin shows how often your account hit the maximum drawdown limit across all simulations. If this exceeds 40%, reduce your risk per trade or improve your R:R ratio before attempting an evaluation.
Increase your win rate by 5%. Even a small improvement from 50% to 55% can dramatically increase your pass probability. Focus on better entry timing and avoiding low-quality setups.
Improve your R:R to at least 1:2. A 2:1 reward-to-risk ratio means your winners are twice as large as your losers. This compensates for a lower win rate and significantly improves pass probability.
Reduce risk per trade to 0.5-1%. Lower risk per trade means more trades before hitting drawdown, giving your edge more time to play out across a larger sample.
Trade more consistently. Trading 15-20 days/month instead of 5-10 gives your strategy more opportunities. Consistency is how edges compound over time.
Test different scenarios. Run the simulator with your current stats, then tweak one variable at a time. Find the minimum improvement needed to reach 60%+ pass rate.
Industry data suggests only 4-10% of traders pass their evaluation. The three main reasons for failure:
Over-trading: Taking 15+ trades per day when your edge only appears 3-5 times. More trades does not equal more profit — it equals more commissions and more emotional decisions.
Revenge trading: After a loss, immediately taking another trade to "make it back." This is the #1 account killer. The simulator shows why — a losing streak followed by revenge trades almost always triggers drawdown.
Incorrect position sizing: Trading too large relative to drawdown. Use our Risk Calculator to find the right size, then run it through this simulator to validate.
The simulator helps prevent all three — by showing you BEFORE you start whether your strategy has a realistic chance of passing. Don't waste $100+ on an evaluation without simulating first.
Everything about Monte Carlo simulations and optimizing your prop firm challenges
Our simulator runs 10,000 simulations of your trading strategy using your actual statistics (win rate, average gains/losses). Each simulation generates a possible path with random variations, allowing for a statistically reliable success probability calculation.
With 10,000 simulations, the margin of error is less than 1%. Accuracy mainly depends on your input data: use at least 100 historical trades for reliable statistics. The simulator integrates real prop firm rules to maximize realism.
1-Step: Faster but higher targets (8-10%). 2-Step: Standard with progressive phases (8% then 5%). 3-Step: More phases but lower targets per phase. The simulator calculates your chances for each type - choose the one with the best probability.
Challenge mode simulates passing the evaluation phases. Funded mode projects your performance over 12 months after getting the account, including splits (80/20 to 90/10), violation risks and net income. Use Challenge for evaluation, Funded to plan your income.
65%+ = Excellent strategy, take the challenge. 50-65% = Correct, optimize further. <50% = Risky, improve your strategy. The color code guides you: green (>65%), yellow (50-65%), red (<50%).
