What is Trailing Drawdown?
A trailing drawdown is a dynamic risk parameter in prop trading where the maximum loss threshold continuously ratchets upward as an account's equity rises. Unlike a static drawdown, trailing drawdown permanently locks in higher loss floors when open or closed profits increase, narrowing the remaining buffer if profits subsequent to the peak retreat.
Mathematical Calculation
Peak Equity represents the highest account equity reached during the evaluation or session. The Max Allowed Drawdown (typically $1,500 to $3,000) is subtracted from this peak. The Lock Level is the starting balance plus an optional buffer (e.g., $100), after which the floor becomes static and ceases trailing.

ES Futures 50K Account Scenario
Initial State: Account balance is $50,000. Liquidation floor is set at $47,500 ($50,000 - $2,500).
Unrealized Gain: You enter long 2 ES contracts. Open profit peaks at +$2,000 ($52,000 open equity).
Floor Adjustment: On intraday trailing plans, the threshold ratchets upward to $49,500 ($52,000 - $2,500).
Pullback & Exit: Market retraces; you exit at +$800 ($50,800 realized balance).
The Trap: Your balance is $50,800, but your liquidation floor remains locked at $49,500. Your remaining buffer is now only $1,300 instead of the initial $2,500.
