Invalidation
Your stop should mean the idea is wrong
Before entry, write why the stop exists. If price reaches that level, what has changed about the setup?
Trading mistake
Moving stop loss hides the moment your trade idea became invalid.

A stop loss is supposed to mark invalidation. When you move it because you do not want to accept the loss, the trade changes from planned risk into emotional exposure.
Behavior
Most stop movement is emotional
Common reasons include hope, fear, revenge, and refusing to take a small loss. Journal the emotion without making it dramatic.
Cost
Measure the extra loss in R
If a planned 1R loss becomes 2.5R because the stop moved, your journal should show that clearly.
Rule
Use a screenshot and fixed invalidation rule
Save the setup screenshot and make stop movement a rule-break tag unless it was part of a planned trailing method.
Checklist
Use this before the next trade
Original stop written before entry
Invalidation reason clear
Any stop movement marked
Emotion recorded
Extra R loss calculated
FAQ
Common questions
Is it always bad to move stop loss?
Not always. Planned trailing is different. Emotional stop widening after price moves against you is the dangerous pattern.
How do I fix moving stops?
Journal original stop, moved stop, reason, and final R. Then create a rule that stop widening is not allowed after entry.
