Would your strategy survive a prop-firm challenge?
A prop firm sells you a paid evaluation: hit a profit target without breaking its loss limits, and it funds an account you can trade. Most people never pass — the drawdown rules end the run, and the firm keeps the fee. The honest thing to do before you pay is to test the strategy you'd actually trade against those kinds of rules and see, on real history, where it would have blown up. That's all this does.
Representative rules, not any firm's official terms. The profiles below are illustrative shapes of how these challenges commonly work — real firms' exact targets, limits and fine print differ and change often. We are not affiliated with any prop firm, we don't reproduce any firm's current rules, and a clean result here is not a prediction that you'd pass a real one. Adjust the numbers to match your firm when you run the live check.
The two common shapes
Almost every challenge is a variation on one of these. The difference between them is the loss limit — and that difference is what decides most challenges.
The fixed-limit evaluation
The shape most FX and CFD evaluations use: hit a profit target without ever losing more than a fixed amount measured from your starting balance, and without a single day losing more than the daily cap.
- Profit target
- 10% of the account
- Max total loss
- 10% (fixed — from the starting balance)
- Max daily loss
- 5% in any one day
- Minimum trading days
- 4 days
- Time limit
- None — we check over ~252 trading days
Representative numbers — not any firm's official rules.
The trailing-drawdown challenge
The shape most futures programs use: the loss limit follows your account's running peak, so a good run quietly raises the floor you can't fall back through. Because that peak is tracked intraday, it's the shape that most often ends a challenge on a single bad move.
- Profit target
- 6% of the account
- Max total loss
- 6% (trailing — from the account's running intraday peak)
- Minimum trading days
- 5 days
- Time limit
- None — we check over ~252 trading days
Representative numbers — not any firm's official rules.
Why the drawdown rule ends most challenges
A profit target rewards a good stretch; the loss limit punishes a single bad one — and the loss limit is the harder wall. A trailing limit is harder still: every new high raises the floor you can't fall back through, so a strategy that gives back a normal amount of an open gain can breach even while it's up on the day. Firms enforce these limits intraday, on your running balance — not just at the close — so the honest test has to assume the worst point within each day, not just where the day ended.
How the honest check works
- • It runs your strategy on real history and tracks the actual account balance a firm would measure — not the “beat buy & hold” number used elsewhere on the site (a firm measures the account, full stop).
- • It tests every loss limit against the worst point inside each day, so a computed breach is the reliable read: worst case, the account reached that level.
- • It slides the challenge across every independent window in the history and reports the spread — never one cherry-picked start — and leads with the fastest blow-up.
- • It will tell you honestly where it would have breached. It will never tell you that you'll pass — the intraday path a real account takes is unknowable from daily data, so “didn't breach” is as far as an honest test can go.
Pick a strategy and an asset, and see where it would have breached a representative challenge — for free, before you risk an evaluation fee. If it blows up on history, that's the cheapest lesson you'll ever get.
