Trailing Drawdown

Drawdown & Loss Limits

Source review:

According to Vigil's prop trading glossary, Trailing Drawdown is a maximum loss threshold that moves upward as your account reaches new equity highs. Unlike static drawdown, the floor rises with profits, meaning gains raise the minimum balance you must maintain. In prop trading, understanding trailing drawdown is critical because it directly affects your drawdown limits, position sizing, and whether you pass or fail an evaluation.

How trailing drawdown works: as your account grows, the drawdown floor rises with it.
How does trailing drawdown work?

Trailing drawdown is the most misunderstood rule in prop trading. When your account hits a new high-water mark, the drawdown floor moves up by the same amount. This means your profit cushion never actually grows until the trail "locks in" at the original account balance.

There are two variants: EOD trailing (floor updates at end of day based on closing balance) and intraday trailing (floor updates tick-by-tick in real time). EOD trailing is more forgiving because intraday spikes in profit do not permanently raise the floor. Intraday trailing is the strictest type.

Understanding which type your firm uses is critical. Many traders blow accounts because they assume static drawdown rules when the firm actually uses trailing. Always check whether drawdown is calculated from balance or equity, and whether it trails intraday or EOD.

What does trailing drawdown look like in practice?

On a TopStep $50K account with $1,500 trailing EOD drawdown: you start with a floor at $48,500. You profit $2,000 and close the day at $52,000. The floor moves up to $50,500. If you then lose $1,600, your balance drops to $50,400 -- below the $50,500 floor. Account terminated, even though you were still above your starting balance.

Why does trailing drawdown matter for prop firm traders?

Trailing Drawdown is the rule that ends most evaluations. Every position sizing decision flows from how your firm calculates it. Get it wrong and the account is gone before your strategy has time to work.

Practical example across firms: FTMO: 2-step, static drawdown, 5% daily loss, from €155. TopStep: 1-step, trailing drawdown, 2% daily loss, from $49.

Common mistake: The most common mistake with trailing drawdown: assuming it works the same across firms. Static vs trailing drawdown can be the difference between surviving a losing streak and blowing an account that is still net profitable. Calculate your room in dollar terms for your specific firm before trade one.

What terms are related to trailing drawdown?

Static Drawdown

A fixed maximum loss threshold set at account opening that never moves, regardless of how much profit you accumulate. Your drawdown floor stays at the same level for the lifetime of the account.

EOD Drawdown (End-of-Day Trailing)

A trailing drawdown variant where the floor only updates at the end of each trading day based on the closing balance. Intraday profit spikes do not permanently raise the floor, making it more forgiving than intraday trailing.

Intraday Drawdown (Real-Time Trailing)

The strictest trailing drawdown variant where the floor moves upward tick-by-tick as your equity reaches new highs during the trading session. Every unrealized profit spike permanently raises the minimum balance required.

Drawdown Floor

The minimum account balance or equity level before a prop firm terminates the account. If your balance or equity touches this level, the account is immediately closed and the evaluation or funded status is lost.

Equity-Based Drawdown

A drawdown calculation method that includes unrealized (open) trade profits and losses in the account value. Your equity fluctuates with every tick while positions are open, making this stricter than balance-based drawdown.
