Prop Firm Rules Explained: The Rules That End Accounts
Every common prop firm evaluation rule in one place: profit target, max loss, daily loss limit, consistency, minimum days, position limits and news rules.
A prop firm evaluation is a set of rules wrapped around a trading account. You pass by reaching a profit target without breaking any of them, and most failed evaluations are failed by a rule, not by a lack of profit. These are the rules you will meet most often, what each one means, and where to read more.
The rules at a glance
| Rule | What it means | Typical example ($50,000 futures account) |
|---|---|---|
| Profit target | Profit you need to pass | $3,000 |
| Max loss | How far the account may fall in total, often trailing from your highest balance | $2,000, trailing at the end of each day |
| Daily loss limit | How much you may lose in one day | $1,000 |
| Consistency rule | Your best day may be at most a share of total profit | 40% to 50% |
| Minimum trading days | Days you must trade before passing | 5 days |
| Max position size | Contracts you may hold at once | 5 minis or 50 micros |
| News rules | Trading may be limited around major releases | No new trades a few minutes before and after |
| Holding rules | Positions may need to be closed before the session ends or the weekend | Flat by the close |
Example numbers only. Every firm sets its own, and they change often.
Profit target
The finish line. It only counts if you reach it without breaking another rule, and with a consistency rule a big day can move it further away.
Max loss and the trailing drawdown
The floor under the account. Static floors never move; trailing floors rise with your highest balance until they reach the starting balance. This rule fails more traders than any other. Read trailing drawdown explained.
Daily loss limit
A cap on one day's loss, open trades and fees included, that resets every trading day. Some firms fail the account at the limit; others close your trades and stop you for the day. Read the daily loss limit.
Consistency rule
No single day may be more than a set share of your total profit. It stops one lucky day from passing, and it can turn a great day into a bigger target. Read the consistency rule.
Minimum trading days
You may need to trade a minimum number of days, sometimes days with at least a small profit, before you can pass or request a payout.
Position limits
A cap on how many contracts you hold at once, often written as minis or ten times as many micros. Some firms raise it as your balance grows.
News and holding rules
Some firms restrict trading around major scheduled releases, such as the Fed's rate decisions (see FOMC days), and many require you to be flat before the session closes or over the weekend.
Funded account rules
Passing leads to a funded account with its own rules for payouts: profit splits, buffers, payout caps and more. Read funded account payouts.
