Funded Challenge Simulator
New LabEstimate prop challenge pass rates and average trades to target by testing risk-per-trade choices.
How to use this Funded Challenge Simulator
Set starting balance, profit target, daily drawdown limit, max drawdown limit, win rate, risk-to-reward ratio, and risk-per-trade options. Simulate prop firm challenge paths to estimate the probability of passing versus breaching limits.
Challenge Setup
Change seed to test a different random path sample.
Simulator Ready
Select risk levels and click Simulate to run 300 trial paths per risk level.

Funded Challenge Simulator Guide
Proprietary trading firm challenges constrain your risk with strict drawdown limits. This tool simulates how different risk-per-trade settings impact your chance of passing a challenge given your system edge.
How to use this tool
- 1Enter the challenge account size to see pass and fail targets in rupees or dollars.
- 2Input your system win rate and average R:R.
- 3Enter the prop firm phase requirements (e.g., 6% target, 5% max drawdown).
- 4Select multiple risk-per-trade levels to compare their pass rates side by side.
- 5Adjust the simulation seed to ensure your pass rate holds up across different random distributions.
Key metrics
Pass Rate
The percentage of simulated runs that reached the target profit before hitting the max drawdown.
How to use it: Use this to optimize risk per trade. Higher risk often lowers pass rate because normal losing streaks trigger the drawdown rule faster.
Average Trades
The average number of trades it took to pass the challenge for the runs that succeeded.
How to use it: Lower risk sizes take longer to pass. Ensure the average trades fit within the time limit (if the firm has one).
Pass Target
The final account balance required to pass the phase.
How to use it: Calculated from account capital and target percentage.
Fail Floor
The account balance that triggers a challenge failure.
How to use it: Prop firms calculate this differently (trailing vs static drawdown). This tool uses a static absolute drawdown from starting balance as a baseline.
Formulas used
Trade P&L
Win = Account Capital × Risk % × R:REach trade size is fixed based on starting capital risk.
Failure Condition
Account Equity ≤ (Starting Capital × (1 − Drawdown %))If your balance touches the drawdown floor, the run stops and counts as a fail.
Example
A 50% win rate system with 1.5 R:R might pass an 8% target/5% drawdown challenge 70% of the time risking 0.5% per trade. If you increase risk to 2% to "pass faster", the pass rate might drop to 30% because a 3-loss streak instantly breaches the 5% drawdown limit.
Common mistakes to avoid
- • Do not assume high risk is better. Drawdown limits punish high risk.
- • Do not forget that prop firms have different rules (e.g. trailing drawdown). Always read their specific terms.
- • Do not change risk mid-challenge without recalculating the probabilities.
