Trailing Drawdown Explained: Why Your Loss Limit Moves Up
A trailing drawdown is a loss limit that moves up as your account balance grows. Many prop firms use it in their evaluations and funded accounts. It sounds simple. In practice, however, it catches a lot of traders off guard. This guide explains how it works and how to plan around it.
What is a trailing drawdown?
Every funded account has a floor. If your balance falls to that floor, the account fails. With a fixed drawdown, the floor stays in one place. With a trailing drawdown, on the other hand, the floor follows your account up.
Here is a simple example. Say an account starts at $50,000 with a $2,000 trailing drawdown. The floor starts at $48,000. Now you make $1,000, and your balance reaches $51,000. The floor moves up to $49,000. Then you give back $2,000. Your balance is $49,000, and the account fails, even though you only lost $1,000 from where you started.
In short, the trailing drawdown measures losses from your highest point, not from your starting balance.
Intraday vs. end-of-day trailing drawdown
Firms do not all track the high point the same way. The two most common methods are:
- Intraday trailing. The floor follows your highest balance during the day, including open profit. So if a trade is up $800 and then reverses, the floor may already have moved up by $800.
- End-of-day trailing. The floor only updates based on your balance at the close. Open profit during the day does not move it.
As a result, intraday trailing is usually tighter. A trade that runs in your favor and then comes back to breakeven can still eat into your room. Always read your firm’s rulebook to see which method applies.
When does the trailing drawdown stop?
At many firms, the trailing drawdown does not trail forever. Instead, it stops once the floor reaches a set level, often the starting balance or a small amount above it. After that, the floor stays fixed.
This is an important milestone. Until you reach it, every new high moves your floor up. Once you pass it, you get a stable cushion to trade with. The exact rule varies, so check your firm’s terms.
How a trailing drawdown changes your trading
Because the floor follows your peak, a few habits matter more than usual.
First, protect open profit. If you use intraday trailing, letting a big winner turn into a scratch can cost you real room. Second, size down when you are close to the floor. A normal-size loss can end the account when your cushion is thin. Third, set a daily stop well inside the drawdown, so one bad day cannot take you out.
It also helps to know exactly what each trade risks in dollars. Our guide to futures tick value shows how to turn ticks into dollars. For a full look at evaluations, payouts, and rules, see how a prop firm funded account works.
A simple trailing drawdown checklist
Before you trade a funded account, answer these questions:
- Is the drawdown fixed or trailing?
- If it trails, is it intraday or end-of-day?
- At what level does it stop trailing?
- Is there a separate daily loss limit?
- How much room do I have right now, in dollars?
Write the answers down. Then update your room each day before you place a trade.
Protect yourself from bad actors
Not every firm is clear about its rules. Before you pay for an evaluation, read the terms in full and look for a public payout history. The CFTC’s Learn and Protect hub also explains common red flags in futures trading.
The bottom line
A trailing drawdown measures losses from your highest point, not your starting balance. That makes it tighter than it looks. Learn which type your firm uses, find out when it stops trailing, and size every trade with your current room in mind.
