Every prop firm has its own set of rules that traders must follow during both the evaluation and funded phases. Understanding these rules inside and out is the difference between passing and failing. In this article, we'll break down the most common rule types you'll encounter and explain what they mean for your trading strategy.

Drawdown Types

Drawdown limits are the most critical rules to understand because breaking them typically results in immediate account failure. There are two main types you'll encounter: trailing drawdown and static drawdown.

A trailing drawdown follows your account balance upward as you make profits, but it never moves back down. For example, if your trailing drawdown is set at $4,000 on a $50K account and you make $2,000 in profit, your drawdown threshold moves up to $6,000. However, if you then lose $1,500, you're still above the new threshold. But if your balance dips below the trailing level at any point, the account is failed. Some firms reset the trailing drawdown once you've earned enough profit, while others trail indefinitely.

A static drawdown, on the other hand, stays at a fixed dollar amount from your starting balance. On a $50K account with a $2,500 static drawdown, your equity can never drop below $47,500 regardless of how much profit you've accumulated. Static drawdowns are generally more forgiving for traders who experience pullbacks after strong winning streaks.

Profit Targets

Profit targets define how much you need to earn to pass each phase of an evaluation. In a standard 2-step evaluation, Phase 1 typically requires an 8-10% gain, while Phase 2 requires 5%. These targets are calculated as a percentage of your starting account balance, not your current equity.

Some firms have moved to target-free models where traders are evaluated based on consistency and rule adherence rather than hitting a specific profit number. This approach reduces the temptation to over-leverage in an attempt to reach a target quickly. When comparing firms, pay attention to whether profit targets include or exclude commissions and swap fees, as this can affect your net performance.

Consistency Rules

Consistency rules are designed to ensure you're trading sustainably rather than gambling your way to profit targets. The most common consistency rule limits how much of your total profit can come from a single trading day. A typical rule might state that no single day can account for more than 30-40% of your total profit.

Some firms also require a minimum number of trading days — usually 5-10 days — before you can pass an evaluation. This prevents traders from passing in a single lucky trade. While these rules can feel restrictive, they exist to protect both you and the firm. Traders who pass evaluations with consistent, disciplined approaches tend to perform much better when managing funded accounts.

Trading Hours

Most prop firms restrict trading during high-volatility news events and overnight sessions. Common restrictions include no holding positions through major economic releases like Non-Farm Payrolls or FOMC announcements, and closing all positions before the daily close on Forex pairs.

Some firms are more lenient and allow overnight holding as long as you're not trading during specific news windows. Futures firms typically have their own set of rules around session hours, as CME trading hours differ from Forex markets. Always check the specific trading hours for your firm, as violating these rules — even if your trade is profitable — can result in account termination.

Understanding these rules is the foundation of prop trading success. Before starting any evaluation, read the firm's trading rules document thoroughly and keep it handy during your trading sessions. The traders who succeed long-term are those who respect the rules and build strategies that work within them.
