Hold-Time Discipline

Without intervention, most traders close winners early and losers late. The psychology is clean: a winning trade triggers a 'lock it in' urge that pulls the exit forward, while a losing trade triggers a 'wait for it to come back' urge that pushes the exit out. The net effect is small wins, big losses, and an account that bleeds despite a respectable win rate.

Hold-time discipline is the deliberate reversal. The trader sets the loss exit in advance and honors it without negotiation; the winner exit is allowed to develop on the trade's own terms (a trailing stop, a structural target, a price-action signal). The asymmetry is the entire point: many small losses and a few large winners is the canonical shape of a profitable discretionary trader's distribution.

Measured in the data, hold-time discipline shows up as a winner-to-loser duration ratio greater than one, and an average-win to average-loss ratio significantly greater than one. The two metrics travel together: traders who close winners early also produce a smaller average win, which is the actual cost.
