Prop firm challenge rules, explained

How a challenge works

You pay a one-off fee, which depends on the account size, for an evaluation account of anywhere from $10,000 to $200,000 and more. You trade it under the firm's rules. Reach the target without breaking a rule and you move on to the next phase, or to a funded account where you keep a share of the profit, commonly 70% to 90%. Break a rule and the attempt is over.

The most common formats are:

• Two-step challenges: a first phase with a target of around 8–10%, then a second phase with a lower target, often 5%, under the same loss limits.
• One-step challenges: a single phase with a target of around 10%, usually with tighter loss limits and often a trailing max loss.
• Instant funding: no evaluation at all, in exchange for stricter rules and a higher price.

The details differ from firm to firm and change often, so always read the current rules of the firm you're buying from. The ideas below apply to nearly all of them.

Profit target

The profit target is how much you need to make to pass, as a percentage of the starting balance. On a $100,000 account with an 8% target, you pass when your balance reaches $108,000. Most firms count closed trades only, so a target reached on open profit doesn't count until you close.

The target is the rule that tempts traders into taking too much risk. Without a time limit there's no reason to rush it: risking less per trade takes longer, but it leaves far more room for the losing streaks every strategy has.

Daily loss limit

The daily loss limit caps how much you can lose in one trading day, typically 4–5% of the initial balance. It's measured from your balance at the start of the day, or at some firms from the higher of your balance and equity. On a $100,000 account with a 5% limit, a day that starts at $102,000 fails if equity touches $97,000.

Two details catch people out:

• Open trades count. The limit is on equity, so a trade that's $5,000 in the red fails the account even if you never close it at that price.
• The day resets on the firm's clock, often midnight server time, which for many brokers is 5 pm in New York. A loss in your evening and another early the next morning may fall on the same trading day.

Max loss (max drawdown)

The max loss is the lowest your account can fall during the whole challenge, typically 6–12% of the initial balance. It comes in two kinds:

• Static: a fixed floor. With 10% on $100,000, equity must stay above $90,000 whatever happens.
• Trailing: a floor that rises with your highest balance (or equity), often until it reaches the starting balance. Profit doesn't add to your room the way it does with a static limit.

The difference matters more than the percentages suggest. The guide to trailing vs static drawdown walks through it with examples.

Minimum trading days

Many firms ask you to trade on a minimum number of days, often 3 to 5, before you can pass. A day usually counts when you open at least one trade on it. The rule stops traders passing with one lucky trade, and if you reach the target early, you'll still need to trade on the remaining days before the pass counts.

Time limits

Some challenges must be finished within a set period, such as 30 days for the first phase and 60 for the second. Many firms have dropped time limits altogether, and without a deadline the only pressure to trade is the pressure you put on yourself.

Other rules to check before you buy

• Consistency rules: no single day may make more than a set share of your total profit, such as 30–50%. They're more common on funded accounts.
• News trading: some firms don't allow opening or closing trades in the minutes around high-impact news, especially on funded accounts.
• Weekend holding: some account types require every trade to be closed before the weekend.
• Leverage: often lower on indices and metals than on currency pairs, which limits your position size.
• Banned strategies: copying another trader, exploiting slow price feeds and hedging across accounts are commonly prohibited.

A worked example

Take a $100,000 two-step challenge with an 8% target, a 5% daily loss limit measured from the day's starting balance, a 10% static max loss and four minimum trading days:

Day one ends at $102,500, so day two's floor is $102,500 − $5,000 = $97,500. If a losing trade takes equity to $97,400 on day two, the challenge fails on the daily loss limit, even though the account is only $2,600 below where it started and still $7,400 above the max loss floor.

That's a common way to fail: not one huge loss, but one bad day that runs into the daily limit. The drawdown calculator shows both floors for your own numbers.

How to practise the rules

Reading the rules is easy; trading inside them under pressure is the hard part. On PropDrill you can take the same kind of challenge on real historical charts, replayed candle by candle. Choose the account size and the rules (target, daily loss, static or trailing max loss, minimum days) and the simulator tracks every limit as you trade and ends the attempt the moment one breaks, as a firm would. Size each trade with the position size calculator so a losing streak can't take you past the limits.
