Preserve the decision point
Use a screenshot taken before entry if possible. If you only have the completed chart, hide future candles in replay. Write the reason for the level, the evidence that qualified the break, and the planned invalidation without referring to the outcome.
Ask process questions
Was the level visible and tested? Did the break close where your rules require? Was there enough unobstructed room to the next opposing structure? Did the pullback show the response you had defined? Was size calculated from the actual stop distance?
A “no” identifies a process deviation. A series of “yes” answers can still end in a loss. Strategy samples contain failed trades; the task is to see whether the loss belonged to the plan.
Record the first contrary fact
Mark the first candle or structural event that challenged the premise. Then compare it with your actual exit. This separates ordinary uncertainty from hesitation after invalidation. Finish with one modest adjustment—never rebuild the whole method around one chart.
