What Happens When You Break a Prop Firm Rule?
Break a prop firm rule and the account can end in a single fill, or a payout can disappear weeks later. Which one you face depends on the rule, and on how your firm words it.
Short answer
Breaching a hard limit, like the maximum drawdown or daily loss limit, usually ends the evaluation or funded account at once. Softer breaches, like some consistency or conduct rules, may remove profits or delay a payout without closing the account. Many firms sell a reset after a failed evaluation.
$1,020 lost. The daily limit was $1,000. An overshoot that small is enough to fail an account, and it helps to see how it happens before looking at what the firm does next.
Why does a $20 overshoot fail the account?
A loss limit is a line, and the firm’s system checks it mechanically. Crossing it by a dollar counts the same as crossing it by a thousand.
The usual ways it happens are small. Commissions pushed a $990 trading loss past the line. A stop slipped a few ticks. A last trade meant to win the day back lost instead. If the firm measures the daily loss limit against live equity, the breach can happen while a trade is open and still recoverable, which means the close is irrelevant and the account is gone at the worst moment of the day, whatever the price does afterward.
Which breaches end the account?
The hard ones. Maximum drawdown and the daily loss limit are the rules most firms enforce automatically and without discussion, and a breach usually ends the evaluation or the funded account on the spot, often with open positions closed for you. Trailing drawdowns make this more likely than it looks, because the floor moves up with your gains and a normal pullback from a new high can reach it, which is the case argued in the intraday trailing drawdown punishes giving back.
Nobody negotiates a hard breach. The account shows as failed, and trading stops.
What happens to the money in the account?
In an evaluation, nothing you can collect. The balance was never yours, so the fee is the loss. In a funded account, profit that hasn’t been paid out yet generally goes with the account. Payouts already received are a separate question. Some terms let the firm reclaim them if a later review finds a prohibited strategy behind the profit, and a trader who has already spent the money then owes it back, which is a far worse position than a failed account. Look for a clawback or reversal clause in the payout section before your first request.
What counts as a soft breach?
Soft breaches are the rules a firm judges after the fact. Consistency rules are the common example: if one day produced too large a share of your profit, the firm may hold a payout until more trading days even it out, or remove part of the profit, while leaving the account open. Some conduct rules work the same way. So do some news rules, covered in whether you can trade the news in a prop firm account.
Firms label these rules differently. One firm’s soft breach is another’s hard one, so the label in the terms matters more than the name of the rule.
Can you reset a failed evaluation?
Often, yes. Many firms sell a reset, which restarts the evaluation with a fresh balance for a fee that’s usually lower than buying a new one. Some offer a free retry if you finish the period without a breach and without hitting the target. Resets are cheap enough to feel harmless. They add up. Count every reset you buy as part of what the account costs, a sum worked through in budgeting for prop evaluation fees.
What about prohibited strategies?
Firms publish a list of strategies they don’t allow. The details vary, and the list is worth reading line by line before your first trade. Common entries involve exploiting price feed delays, trading opposite positions across accounts, and methods the firm treats as gaming the simulation.
These breaches tend to surface late. The firm reviews your trading when you ask for a payout, and a pattern it considers prohibited can void the payout, cancel profits or close the account, weeks after the trades that caused it. You won’t get a warning at the time.
How do you protect yourself?
Keep your own records. Export your trade history regularly, and take screenshots of the account balance, the drawdown level and any rule dashboard at the end of each day, especially on days near a limit.
If a breach looks wrong, those records are what a support team can check against its own data. A platform outage, a bad price print or a rule applied under the wrong account settings can all be raised, and firms that have a review process usually ask for exactly this kind of evidence. Without it, their log is the only one.
Then build a buffer into your own rules. Stop trading for the day well before the firm’s limit, at a level of your own choosing, so that commissions and slippage on a final exit can’t carry you over the line. The prop firm drawdown calculator shows where the floor sits as your balance changes.

Can you appeal a prop firm breach?
Some firms have a support or review process for disputed breaches, most often where a platform fault or bad price data is involved. Your own trade history and dated screenshots are the evidence that carries weight, so keep them from the first day.
Do you get your evaluation fee back after a breach?
Generally no. The fee pays for the attempt, and a breach ends it. Some firms refund the evaluation fee along with a first payout once you're funded, which a breach rules out. Refund and reset terms vary between firms, so read that part of your firm's rules before the first trade.
