Prop-firm / funded-account rules and compliance
How prop-firm challenges and funded accounts typically work — profit targets, daily and maximum loss limits, static vs trailing drawdown, and common restrictions — and how to adapt your risk so a rule, not the market, never ends your account.
Lesson 3 of 3 · 6 min read
Proprietary trading firms ("prop firms") offer traders access to larger account sizes in exchange for passing an evaluation and following strict rules. For many traders, the rules — not the market — are what end the attempt: a single day over the loss limit, a trailing drawdown misunderstood, a news trade that breaks the terms. This lesson explains how these programmes commonly work and how to turn their rules into your own risk plan.
What you'll learn
- How a typical evaluation ("challenge") and funded account are structured
- Daily loss limits: balance-based vs equity-based
- Maximum loss: static vs trailing drawdown
- Common restrictions that disqualify traders
- A risk plan designed to stay well inside the rules
1. The typical structure
Programmes vary widely, but many follow a pattern like this:
| Stage | Typical requirements (illustrative ranges) |
|---|---|
| Phase 1 (evaluation) | Profit target around 8–10%, within a daily and maximum loss limit, often with a minimum number of trading days |
| Phase 2 (verification) | A lower profit target, often around 5%, under the same loss limits |
| Funded account | No profit target; keep within the loss limits; profits are split with the firm |
Most firms charge a fee for the evaluation. Understand the business model: firms earn from evaluation fees as well as from funded traders, and many traders don't pass. Treat the fee as a real cost, and read every rule before paying.
2. Daily loss limits
A daily loss limit (commonly around 5%) caps how much you can lose in one day. The critical detail is what it's measured from:
| Method | Measured from | Includes open positions? |
|---|---|---|
| Balance-based | The day's starting balance | Often only closed losses — check |
| Equity-based | The day's starting equity (or the higher of balance and equity) | Yes — floating losses count |
Worked example
(Illustrative.) $100,000 account, 5% daily loss limit based on the day's starting equity of $100,000 → equity must not fall below $95,000 at any moment today.
You have a trade open with a $3,000 floating loss, then open another that moves $2,100 against you. Equity touches $94,900 for a few seconds before recovering. On an equity-based rule, the account can be breached — even if both trades later finish in profit.
3. Maximum loss: static vs trailing
The maximum loss (commonly around 10%) is the absolute floor for the account.
| Type | How the floor behaves |
|---|---|
| Static | Fixed from the starting balance — e.g. $90,000 on a $100,000 account, forever |
| Trailing | Moves up as your balance or equity reaches new highs (sometimes until it reaches the starting balance), then may lock |
(Illustrative trailing drawdown.) $100,000 account with a 10% trailing limit. You grow to $106,000 → the floor rises to $96,000. A normal 10% "room" is now only $10,000 from your peak, not from the start — and gains you haven't withdrawn are what's at risk.
4. Common restrictions
Depending on the firm, you may encounter:
- Minimum trading days before passing
- Consistency rules — for example, no single day can account for more than a set share of total profit
- News trading restrictions around high-impact releases (see Trading NFP, CPI, and rate decisions)
- Weekend or overnight holding limits on some account types
- Maximum lot sizes or leverage limits
- Prohibited practices, such as exploiting price-feed delays, certain high-frequency methods, or copying the same trades across many accounts
- Inactivity rules
5. A rule-proof risk plan
Build a buffer so the rules are never the thing that stops you:
| Rule | Illustrative firm limit | Your own limit |
|---|---|---|
| Risk per trade | — | 0.25–0.5% (not 1–2%) |
| Daily loss | 5% | Stop trading at 2% for the day |
| Maximum loss | 10% | Reduce risk sharply from 4% drawdown; stop at 6% and review |
| News | Restricted | No open positions from 15 minutes before to 15 minutes after high-impact releases |
Why so conservative? With a 5% daily limit and 1% risk per trade, five losses in a day — or a gap through two stops — ends the account. With 0.5% risk and a personal 2% daily stop, a normal bad day is survivable.
Time is on your side. Most evaluations either have no time limit or allow ample time. Reaching an 8% target at 0.5% risk per trade with a 2 : 1 reward-to-risk strategy may take weeks — that's fine. Rushing is the most common way to fail.
Common beginner mistakes
- Not knowing whether the daily limit is balance- or equity-based.
- Misunderstanding trailing drawdown after early profits.
- Trading 1–2% per trade under a 5% daily limit.
- Trading news on an account that restricts it.
- Rushing to hit the profit target quickly.
Key terms
| Term | Meaning |
|---|---|
| Prop firm | A company that funds traders who pass its evaluation and follow its rules |
| Evaluation / challenge | The qualifying phase(s) before a funded account |
| Daily loss limit | Maximum allowed loss in a single day |
| Static drawdown | A fixed maximum-loss floor |
| Trailing drawdown | A maximum-loss floor that rises with new highs |
| Consistency rule | A limit on how much profit can come from a single day or trade |
| Profit split | The share of funded-account profits paid to the trader |
Practice
- Pick one prop-firm programme and write down every rule in your own words: targets, daily and maximum loss (and how each is measured), and restrictions.
- Draw the daily and maximum-loss floors for day one of a $100,000 account.
- Write your own buffered limits — risk per trade, daily stop, and drawdown actions.
- Using your backtest statistics, estimate how many trades you'd need to reach an 8% target at 0.5% risk per trade.
Quick recap
- Programmes typically have an evaluation, a verification, and a funded stage — but rules vary widely.
- Know exactly how the daily loss is measured — floating losses often count.
- Trailing drawdown moves up with new highs and can shrink your room quickly.
- Watch for consistency, news, holding, and prohibited-practice rules.
- Trade with your own tighter limits so a rule is never what ends the account.
