In simple terms
“I cut the winner too early” means price continued favorably after the exit and the trader believes part of the move was missed. The diagnosis is sound only when the exit broke a rule or ignored information already available.
The right check
Reconstruct the planned reason, actual reason, planned and filled prices, and whether invalidation had occurred. An exit driven by fear while the plan remained valid differs from one caused by a stop, time limit, changed risk, or reached target.
The later high is not enough
Future price was unknown when the decision was made. Using it as the only benchmark makes every imperfect exit look wrong. A journal may record later favorable excursion within a predefined window, but the final high is not profit that was certainly available.
Selling winners too soon can reflect the disposition effect. One case does not establish the bias; a series of comparable trades is needed.
