Trailing Drawdown, Explained for Funded Traders
Trailing drawdown is the rule that ends most funded accounts. Here's how it works, how it differs across firms, and how to size around it.
More funded accounts die to trailing drawdown than to any single bad trade. The mechanic is simple on paper and unforgiving in practice. If you trade a funded account, understanding it cold is non-negotiable.
What trailing drawdown actually is
A trailing drawdown is a moving floor under your account equity. As your account makes new highs, the floor moves up with it. As soon as your equity touches that floor, the account is closed. The floor only moves up. It never moves down.
The two variations that matter
- End-of-day trailing: the floor recalculates based on your closing balance each day. Intraday spikes do not move the floor.
- Intraday trailing: the floor recalculates based on the highest equity point ever reached, including unrealized profit. A green spike that you give back can quietly raise your floor and end the account.
Most failed accounts are killed by intraday trailing combined with a winning trade that was held too long. The trader saw green, did not lock it in, watched it round-trip, and discovered the floor had moved up while they were not looking.
How to size around it
- Know the rule for your specific firm and account size. Do not assume.
- Treat the trailing distance as your real risk budget, not the listed account size.
- Cap per-trade risk at a small fraction of the trailing distance, typically one to two percent.
- Plan exits before entry, especially profit targets, so unrealized gains are not allowed to drift.
- Use a system that enforces these caps mechanically, not just a sticky note on the monitor.
Where automation helps
An automation layer that knows your trailing rule can refuse trades that would push exposure past the floor, lock in profits before they round-trip, and stop trading entirely once the day's risk budget is spent. None of that requires a model. It requires a system that takes the rule seriously.
