Discipline Slippage
The gradual erosion of trading rules over time — small exceptions that compound into a completely undisciplined approach.
Discipline slippage is how most rule-breaking actually happens: not in one dramatic decision, but through a series of small exceptions that each feel justified. "I'll just move the stop this once." "I'll skip the checklist today, I know this setup." Each exception normalises the next one.
It is especially common after a period of success. The rules feel like constraints that have been holding you back. They haven't — they have been the structure enabling your success. But after a few wins, they feel optional.
Combat slippage with the journal: track every rule break, no matter how minor. If a pattern appears — the same rule broken repeatedly — treat it as a system failure requiring a structural fix, not more willpower.
