Prop Firm Rules: The Complete Guide

Every prop firm rule exists for one reason: to find out whether you can make money without ever losing control of the account. That is the whole test. Most traders read the profit target carefully and skim everything else, which is precisely backwards, because almost nobody fails from missing the target. They fail from a rule they did not know applied to them. This is every rule in one place, what each one means in practice, and which ones actually end accounts.

1. Profit target

The gain you must reach to pass, commonly around 8 to 10 percent of the starting balance, and often lower on the second phase of a two step challenge. It is the only rule that asks you to do something rather than avoid something, which is why it gets all the attention and causes the least damage.

In practice: break it into a small daily number instead of chasing it. A 10 percent target is only 0.5 percent a day over a month. See how long it takes to pass.

2. Minimum trading days

The least number of days on which you must place at least one trade, usually three to five. You cannot pass before satisfying it, no matter how fast you reach the target.

In practice: this quietly ends accounts that had already won. A trader hits the target early, still owes two days, and takes loose trades to stay active. If you reach the target ahead of the minimum, shrink your risk to almost nothing and place small clean trades purely to tick off the days.

3. Daily loss limit ⚠

The maximum you may lose in one trading day, commonly around 5 percent, resetting at the firm's daily cutoff. Whether it is measured on balance (closed trades only) or equity (including open floating losses) matters enormously, because on an equity based limit an open losing trade can breach you before you close it.

In practice: set your own daily stop well inside the firm's number, and close the platform when you hit it. Full detail in drawdown rules explained.

4. Maximum drawdown ⚠

The total the account may fall before it is failed, commonly 10 percent. This comes in two forms and the difference decides how you should trade:

• Static: measured from the original starting balance. The floor never moves, so profit builds a real cushion.
• Trailing: measured from the account's highest point, so the floor rises as you profit. Traders lose accounts to this while still up on the month.

In practice: know which one you have before your first trade. The comparison is in static vs trailing drawdown.

5. Consistency rule ⚠

A cap on how much of your total profit may come from a single day or a single trade, often expressed as a percentage of the total. It exists so that nobody passes on one lucky position.

In practice: it can block a payout on an account that is genuinely in profit, which is why it surprises people at the worst moment. If you have an unusually large day, keep trading modestly afterwards so the distribution evens out. See the consistency rule explained.

6. News trading restriction ⚠

Where a firm has one, it forbids opening or closing trades in a tight window around high impact releases, and sometimes forbids holding a position through one at all.

In practice: the version that catches careful traders is holding, not trading. A position opened an hour earlier and simply left open can be a violation. Keep an economic calendar open. See news trading rules.

7. Weekend and overnight holding ⚠

Whether positions may be left open through the daily rollover or through the Friday close. Firms differ enormously here, and some ban only the weekend.

In practice: the market enforces its own penalty even where the firm allows it, because a weekend gap can jump straight past your stop. Also watch swap charges on anything held for weeks. See weekend and overnight rules.

8. Leverage limits

How much position size your margin permits, commonly around 1:100 on forex majors and progressively lower on gold, indices and crypto. Some firms reduce leverage once you are funded.

In practice: leverage is a permission, not a risk setting. Your risk comes from position size and stop distance. See how much leverage prop firms give.

9. Rules on robots and copy trading

Many firms permit Expert Advisors, some prohibit them, and several ban specific behaviours rather than automation itself. Commonly restricted: latency or arbitrage strategies, tick scalping that exploits pricing, and copy trading into accounts that are not yours.

In practice: copying between your own accounts is usually fine, while trading on behalf of others is a serious violation almost everywhere. Check before installing anything. See which firms allow trading robots.

10. Prohibited strategies

Beyond automation, most firms explicitly ban a short list: latency arbitrage, exploiting off market or erroneous prices, hedging the same instrument across separate accounts to guarantee one passes, group trading in coordination, and sharing or selling accounts.

In practice: these are treated as serious breaches rather than technicalities, and can void payouts already earned. None of them happen by accident, but the account hedging one occasionally tempts people running several challenges, so it is worth naming.

11. Inactivity

Many firms close accounts left dormant for a set period, often around 30 days without a trade.

In practice: a rule to be aware of if you plan a break. It is the easiest of all of them to avoid and the most annoying to lose an account to.

The five that actually fail accounts

Read the marked items again. In practice, accounts end because of:

1. The daily loss limit, usually after oversizing following a loss.
2. The max drawdown, especially the trailing kind.
3. The consistency rule, discovered at payout time.
4. News, usually by holding rather than by trading.
5. Weekend holding, almost always by forgetting rather than deciding.

Notice that none of those is "the strategy did not work". That is the real lesson of the rulebook, and it is the same conclusion reached in why traders keep failing challenges.

Your pre trade checklist

Before the first trade on any new account, write these down with your firm's actual numbers. It takes twenty minutes and removes an entire category of failure:

• Profit target: ____ %
• Daily loss limit: ____ %, measured on balance or equity: ____
• Max drawdown: ____ %, static or trailing: ____
• Minimum trading days: ____
• Consistency rule: yes or no, cap ____ %
• News restriction: yes or no, window ____
• Weekend holding allowed: yes or no
• Expert Advisors allowed: yes or no
• Leverage on the instruments you trade: ____

The bottom line

Prop firm rules are not obstacles placed in front of a profit target. They are the test itself, and the target is almost incidental. Nearly every failed account is failed by the risk rules rather than by the market, and nearly every one of those failures was a rule the trader could have written on a single page beforehand. Fill in the checklist above before your first trade, keep the two drawdown numbers visible while you trade, and treat the softer rules on news, weekends and consistency as hard, because the firm certainly does.

Almost nobody fails a challenge by missing the target. They fail by breaking a rule they never read.

Educational content only, not financial, investment or trading advice. Rules, thresholds, percentages and enforcement vary by prop firm and change frequently, and the figures here are common industry ranges rather than any specific firm's terms. Most prop-firm accounts are simulated. Always read your own firm's current rulebook before trading. No robot guarantees passing a prop firm challenge or any payout. Trading carries substantial risk of loss.
