Prop firm challenge simulator
1The challenge
Typical rules to start from. Change any number to match your firm.
Leave empty if there is none
Time limit and consistency rule
Trading days per phase. Empty for none
Best day as a share of profitable days' total. Empty for none
2Your trading
The share of your trades that win.
A winner makes 1.5 times what you risk. Losers lose 1R.
Share of the starting balance you lose when a trade hits its stop.
Daily stop
Stop trading for the day after this many losses.

5,000 simulated attempts from your numbers. Trades are taken one at a time and limits are checked as each one closes. A guide, not a promise.
Why profitable strategies still fail
A challenge can end long before your backtest turns a profit.
Daily loss limit
A few losses in one day can end the challenge, even if your strategy is profitable overall.
Max loss
Risk too much and a normal losing streak can use your whole drawdown allowance.
Trailing drawdown
When the limit follows your highest balance, giving back profits can fail the challenge.
Trade order
The same trades can pass or fail in a different order. That is sequence risk.
How the simulator works
It runs your edge 5,000 times, with a different trade sequence each time.
Each attempt takes trades one at a time and checks the rules after every trade closes. It stops when you hit the target, break a limit or run out of time.
Run 5,000 attempts and you get a prop firm pass rate. Or paste real R multiples from your backtest and the simulator reshuffles your results instead of using an average.
Risk changes everything
Risk too little and you may run out of time. Risk too much and a losing streak can end the challenge.
Backtest the challenge properly
Better inputs give you a more useful simulation.
Set the rules
Enter the target, loss limits, minimum days, time limit and any consistency rule.
Backtest without peeking
Replay bar by bar and take every valid setup, including the ugly ones.
Log trades in R
Record each result as an R multiple so you can simulate your actual trade history.
Paste your results
Run your real trades through the rules and compare pass rates across risk levels.
Questions, answered
What is prop firm backtesting?
Prop firm backtesting tests a strategy against challenge rules, not just profitability. You check whether it can reach the profit target without first breaking the daily loss, max loss, minimum trading days or other rules you set.
How accurate is the simulator?
It is only as accurate as your inputs. Trades are taken one at a time and limits are checked as each trade closes. Real trading can differ, including how firms treat open losses. Use the results as a guide, not a promise.
What risk per trade should I use for a prop firm challenge?
There is no single right number. Use the pass rate by risk chart to compare levels. Lower risk can make the target take longer. Higher risk can make daily and maximum loss limits easier to hit.
How many trades should I backtest before a challenge?
There is no fixed number that guarantees a useful result. More trades give the simulator more of your actual outcomes to reshuffle, including losing streaks and different sequences. Avoid drawing big conclusions from a small sample.
