Trailing drawdown that locks, explained with an example

The floor follows your gains up to a set level, often the starting balance plus $100, then stops moving. From there, every gain adds room, like a static drawdown.

Updated October 25, 2026

How it works

At first, the floor follows your high (closing or intraday, depending on the firm) like a normal trailing drawdown.

Once it reaches the lock level, for example $50,100 on a $50,000 account, it stays there for good.

To get there, the account must reach that level plus the max loss: $52,100 in our example.

Worked example

The same days, with a lock at $50,100. On day 2 the $52,500 close would lift the floor to $50,500, but it stops at $50,100.

Day	Day's P&L	Low – high	Close	Floor
1	+$1,200	$50,000 – $51,200	$51,200	$48,000
2	+$1,300	$51,200 – $52,900	$52,500	$49,200
3	−$500	$52,000 – $52,500	$52,000	$50,100
4	+$200	$52,000 – $52,200	$52,200	$50,100
5	−$1,600	$50,300 – $52,200	$50,600	$50,100

The account survives all five days. Final floor: $50,100.

Watch out for

Before the lock it's an ordinary trailing drawdown: the first days are the riskiest.
The lock level depends on the firm, and sometimes on the phase (evaluation or funded).
