Trailing Drawdown

A maximum-loss limit that rises with your account's peak balance instead of staying fixed — the loss rule behind most evaluation failures, and the one most worth mastering.

A trailing drawdown is a moving loss limit. Instead of measuring your maximum allowed loss from your starting balance, the firm measures it from your highest balance reached (the “high-water mark”). As your equity makes new highs, the drawdown floor trails up behind it — but it never comes back down.

Example: a $50K account with a $2,500 trailing drawdown starts with a floor at $47,500. If you run the account up to $52,000, the floor trails up to $49,500. Give back $2,500 from any peak and the account fails — even though you’re still above your starting balance.

The two variants matter enormously:

• Intraday trailing — the floor follows your peak unrealized equity during a trade. Open-trade profit you never banked still raises the floor. This is the harshest variant.
• End-of-day (EOD) trailing — the floor only updates at the daily close, based on your settled balance. Intraday swings don’t move it, which makes risk far easier to plan.

Which variant a firm uses (and whether the trail stops at a certain profit level) differs by firm and account type — check the firm’s rules page in our directory before buying an evaluation. In failure-analysis data cited in our research, loss-limit breaches — not missed profit targets — account for roughly 70% of evaluation failures, and trailing drawdown mechanics are the main reason why.
