Usually the starting balance. 0 = never stops.

How the floor moves

Each day the high-water mark is the highest end-of-day balance so far. The floor is the high-water mark minus the drawdown, but never above the "stops trailing" level. Once the floor reaches that level it stays there, so every dollar above it is cushion you keep. Intraday trailing rules follow the highest open balance instead and can be tighter; read trailing vs static drawdown, explained with numbers.
