Trailing Drawdown
The account rule that follows your high-water mark, and the one most funded traders underestimate.
What it is
A trailing drawdown means your maximum allowed loss moves upward with your highest recorded equity, but never moves back down. If your account starts at $100,000 with a 5% trailing drawdown, your floor is $95,000. If you grow equity to $103,000, your floor moves up to $98,000, permanently.
Why it exists
Firms use trailing drawdown to prevent traders from building a cushion and then gambling with it. Without it, a trader who's up $5,000 could suddenly take reckless trades knowing they have a $5,000 buffer before hitting the absolute drawdown limit. The trailing mechanism keeps you disciplined at all times, not just when you're near the edge.
The two sides
The firm's argument
It enforces consistent risk management. Traders who can't maintain discipline after a winning streak are a liability. The trailing stop protects both the firm's capital and encourages sustainable trading.
The trader's reality
It creates a paradox: the better you trade, the tighter your leash gets. A trader who's up 4% on a 5% trailing account now has only 1% of room before violation, less than when they started. One normal retracement after a good streak can end the account.
Critical differences between firms
- Equity-based vs. balance-based: Some firms trail based on real-time equity (including open P&L), others only on closed-trade balance. Equity-based is significantly stricter, a floating profit that retraces can trigger the violation even if you never closed the trade.
- Trailing stops at initial balance: Some firms (like FTMO) stop trailing once the drawdown floor reaches your starting balance. This means once you're up enough, your trailing drawdown effectively becomes a static maximum drawdown. This is a massive difference.
- End-of-day vs. real-time: Some firms only check at end-of-day, giving you intraday breathing room. Others check tick-by-tick.
