Static vs Trailing Drawdown Explained

Understanding the Mathematics That Determine Survival

Drawdown rules are the single most important variable in any prop firm evaluation. They determine how much room a trader has to absorb losses, and they vary dramatically between firms. Understanding the difference between static and trailing drawdown is not optional. It is the foundation of every position sizing decision a funded trader will make.

Static drawdown sets a fixed loss floor calculated from the initial account balance. On a "00,000 account with a 10 percent static drawdown, the floor is $90,000 for the entire duration of the evaluation and funded period. If the account grows to "15,000 and then pulls back to $91,000, the trader is still within the limit. The floor never moves upward. FTMO, FundedNext, The5ers and DNA Funded all use static drawdown. This structure is mathematically the most favourable for the trader because a strong performance streak cannot subsequently narrow the available loss buffer.

Trailing drawdown adjusts the floor upward as the account's equity (or balance, depending on the firm) reaches new highs. On a "00,000 account with a $3,000 trailing drawdown at Apex Trader Funding, the initial floor is $97,000. If the account reaches "03,000, the floor rises to "00,000. If it then reaches "06,000, the floor moves to "03,000. This means a trader who has a $6,000 winning streak followed by a $3,001 loss will breach the drawdown, despite being $2,999 in net profit. Apex and Topstep both use trailing drawdown models.

Some firms use end of day trailing, where the floor only updates at the close of the trading session based on the closing balance. Others use intraday trailing, where the floor updates in real time based on the highest equity reached during the session. Intraday trailing is significantly more restrictive because a brief spike in unrealised profit during a volatile session can permanently raise the floor even if the trade is subsequently closed at a lower level.

The practical implication is straightforward. Static drawdown rewards traders who can generate consistent net profit over time, regardless of the path taken to get there. Trailing drawdown penalises traders whose equity curves involve significant swings, even if the swings are ultimately profitable. Scalpers and high frequency traders tend to perform better under trailing drawdown because their individual trade impact is small. Swing traders and position traders generally prefer static drawdown because their strategies inherently involve larger open position fluctuations.
