Why Risk Rules Matter
Risk rules are the foundation of every prop trading program. They protect the firm's capital while simultaneously encouraging disciplined trading habits. Understanding these rules is not just about avoiding disqualification; it shapes how you approach each trading session.
Think of risk rules as guardrails. They define the boundaries within which you must operate. Traders who view these rules as constraints tend to struggle, while those who incorporate them into their strategy tend to thrive.
Daily Loss Limits
The daily loss limit is typically set at 4-5% of the starting balance for that day. This means if your account starts the day at $100,000, you cannot lose more than $4,000-$5,000 in that single session. Both realized and unrealized losses count toward this limit.
Some firms calculate this from the start-of-day equity, while others use the previous day's closing balance. The distinction matters, especially for traders who hold overnight positions. Always verify how your specific firm calculates this figure.
Maximum Drawdown
Maximum drawdown is the total loss allowed on the account over the entire evaluation or funded period. It typically ranges from 8-12%. The key distinction is between static and trailing drawdown.
Static drawdown is measured from the initial account balance. Trailing drawdown moves up as your account grows, always maintaining a fixed distance from your highest balance. Trailing drawdowns are more restrictive because profits don't provide a permanent cushion.
Consistency Rules
Many firms implement consistency rules to prevent traders from hitting the profit target through a single lucky trade. These rules may cap the maximum profit on a single day to a percentage of the total target, or require that no single trade represents more than a certain percentage of total profits.
Consistency rules encourage sustainable trading practices. Firms want to fund traders who can generate consistent returns, not those who gamble for outsized gains.
Tips for Staying Compliant
Set personal risk limits that are stricter than the firm's rules. If the firm allows a 5% daily loss, set your personal limit at 3%. This buffer protects you from accidental violations due to slippage or unexpected market moves.
Use the firm's dashboard to monitor your metrics in real-time. Know your current drawdown, daily loss, and position sizes at all times. Many firms also provide email or push notifications when you approach rule limits, so make sure these are enabled.
