What Happens When You Breach Prop Firm Rules

A breach is not a negotiation. On almost every prop firm platform, the moment a rule is triggered the account is closed automatically by the risk engine, usually before you see a notification. Understanding what happens next decides whether the breach costs you a fee or a fee plus a payout claim.

The five typical consequences

The distinction that matters most is challenge versus funded. On a challenge, a breach costs the fee. On a funded account, a breach can cost the fee, the accrued profit, and the account’s entire future earning capacity. The same 1% overshoot is a $500 mistake or a $5,000 mistake depending on which side of funding it happens.

Fee treatment: refund vs credit vs nothing

Refund policies vary more than any other term. Some firms refund the evaluation fee with your first payout. Some return it only if you pass within a set number of days. Some issue a credit rather than cash. Some treat the fee as non-refundable under every circumstance, which is defensible given what the fee buys, but should be known before purchase.

If you breach, ask specifically whether a reset at a discount is available and whether the reset preserves your trade history for the consistency count. A cheap reset with a fresh clock is usually better than a full-price restart, but only if you understand which rules you broke.

The six accidental breaches

Deliberate rule breaking is rare. These are the ones that catch experienced traders.

1. The daily loss limit measured from equity, not balance

You have an open trade that is $600 underwater at midday. You open a second trade, watch the total drawdown hit 5%, and the account closes. Your balance was never down a cent. If the daily limit is measured on equity, unrealised losses count, and a floating position plus a new trade can breach a limit you thought you had room under.

2. The trailing floor that catches a breakeven account

You grow a trailing-drawdown account to $108,000, then flatten out. The floor is now $98,000 and has not moved back. A normal 2% losing day on the balance takes you to $105,840, fine. Two of them and you are inside the trailing band before you realise the band is measured from the high, not from your balance.

Full detail is in our static vs trailing drawdown guide.

3. The news window you did not know applied

Restrictions are often instrument-specific. A firm may allow news trading on indices but restrict it on metals, or restrict it only on the account type you bought. A position opened an hour before a release and held through it counts as news trading on many agreements.

4. The weekend hold on the wrong account

Weekend holding is frequently allowed on standard accounts and prohibited on scaled or promotional ones. Traders who upgrade to a larger account tier lose permissions they had before.

5. The EA that was allowed, but not that way

Expert advisors are commonly permitted. Latency arbitrage, tick-scalping bots, and EAs that open more than a stated number of positions simultaneously are not. An EA licensed for your account is usually fine; an EA shared with three friends is not. See are EAs allowed on prop firms for the full picture.

6. The payout request that arrived one day early

Requesting a payout before the minimum day count, or with an open position, is often logged as a procedural violation rather than a simple rejection. Two or three procedural flags can end an account that never lost money.

How to make a breach survivable

• Keep a written summary of the three rules that can close your account: total drawdown basis, daily loss basis, and the payout window. One page, updated when the firm updates.
• Never run a floating loss larger than a third of your daily limit. That single habit removes most accidental breaches.
• Flatten the account before news, weekends and payout requests until you have confirmed the permissions in writing.
• Screenshot the agreement page for the account type you actually bought, with the date. If a rule changes later, you have evidence of what you agreed to.
• Track the trailing floor daily in the drawdown calculator, not in your head.
• After a breach, read the termination notice for the specific clause before buying a reset. Repeating the same rule mistake is the expensive version.

The reset decision

A reset is worth buying when the breach was a rule misunderstanding you can now name, and when your strategy was actually working. It is not worth buying when the breach was a drawdown caused by oversized positions, because the second attempt will fail the same way with a different date.

Before paying for a reset, model the account as if the rules were twice as strict: half the risk per trade, flat before news, no weekend holds. If the strategy still shows an edge under those constraints, reset. If it only works at full risk, the firm is wrong for the strategy, not the other way around.
