If you search “prop firms that allow martingale”, you will find listicles naming firms that “permit” the strategy. What those lists do not tell you is that the drawdown rules at those same firms make a martingale effectively unpassable. The firm lets you run it, then the loss limits stop you. Here is the honest picture.
Why prop firms ban martingale
The reason is not ideology. It is the drawdown math.
A martingale doubles the lot size after every loss so a single win recovers everything. The tradeoff is that the position size grows exponentially while the drawdown grows with it. A prop firm has a hard daily loss limit, typically 3 to 5 percent, and a hard max loss, typically 10 percent. A martingale hits those limits fast because its recovery trades are huge relative to the account.
The firm is not banning martingale to be difficult. It is banning a strategy that, by construction, breaches the firm’s own drawdown rules within a few losses. The ban and the drawdown limit are two ways of saying the same thing: martingale does not survive here.
The drawdown conflict
Work the numbers. A martingale starting at 0.01 lots on a challenge account, doubling after each loss:
- After 5 losses the next position is 0.32 lots.
- After 6 losses it is 0.64 lots.
- After 7 losses it is 1.28 lots.
By the time you are at 7 or 8 losses, a single adverse move on the doubled position is several percent of the account, which breaches the daily loss limit. You do not need the market to trend far. You need a normal losing streak, which is guaranteed to happen.
This is why even firms that do not list martingale in their prohibited list will still fail you. The drawdown limit does the banning for them.
Firms that nominally allow it
The honest answer to “which prop firms allow martingale” is: almost none explicitly ban the word, and almost all effectively ban the behavior. Read the terms and you will usually find the strategy restrictions phrased around high-frequency trading and arbitrage, not “martingale”. The ban is enforced by the drawdown rules, not by naming the strategy.
Among the firms I track:
- FTMO, FundedNext, The5ers, FXIFY, and FundingPips all allow EAs but constrain the drawdown to the point where a martingale cannot reasonably pass.
If a firm’s marketing explicitly advertises “martingale allowed”, treat that as a warning sign, not a feature. A firm that understands martingale risk is a firm that is either hedging it (with a trailing drawdown that will catch you) or a firm that does not intend to pay you.
Firm-by-firm policy
Rather than a false “allowed vs banned” column, here is what actually happens at each firm:
- FTMO: No explicit martingale ban, but 5 percent daily loss and 10 percent static max loss make a doubling strategy breach within a short losing streak.
- FundedNext: Same structure, 5 percent daily and 10 percent static. Martingale fails on drawdown, not policy.
- The5ers: 5 percent daily loss computed from the prior day’s high makes recovery trading especially dangerous, because a bad day resets your floor.
- FXIFY: 4 percent daily loss is among the tightest, which is the most hostile to a doubling strategy.
- FundingPips: 5 percent daily on the standard program; same drawdown wall.
The pattern is uniform. The firm does not have to ban martingale because the drawdown rules already make it a losing proposition.
Why martingale usually fails a challenge
Even ignoring the rules, the math fails on its own. A challenge has a profit target (8 to 10 percent) you must hit while staying inside a daily loss limit (3 to 5 percent). A martingale’s wins are small and its drawdowns are large. You are trying to accumulate small gains while avoiding one large loss, but the strategy is built to produce exactly one large loss.
The result is predictable: the trader grinds toward the target for weeks, then one losing streak breaches the daily limit and the whole thing is gone. This is not bad luck. It is the strategy working as designed, against a ruleset that punishes exactly what the strategy does.
Safer alternatives
If you like the “recover losses” idea, here is what actually works better, without the ruin risk:
- Fixed-fraction position sizing. Risk the same small percentage per trade, never increase size after a loss. This is the opposite of martingale and survives drawdowns.
- A properly sized grid with fixed lots and a hard max-drawdown stop, which I compare against martingale in grid vs martingale.
- Mean-reversion with a stop. Trade the reversion idea but cap every trade’s risk, so no single position can breach the account.
None of these have the martingale’s “guaranteed recovery” appeal, because that appeal is a fiction. The math in grid trading vs martingale shows why.
Risk warning. Martingale carries near-certain eventual ruin on a leveraged account. On a prop firm, where drawdown limits are hard-coded and a breach ends your challenge, martingale is effectively a fee you are guaranteed to lose. Do not run a recovery strategy on a challenge you cannot afford to fail.
