Mechanism
Discretion feels like intelligence, but most discretion is emotion in disguise.
Overrides are rarely random. They occur under stress: after losses, during spikes, or when ego is threatened.
If you don’t measure overrides, you don’t know what your real strategy is.
Process upgrade: turn this truth into a rule you can actually enforce. If the rule can’t be enforced, it will be broken under stress.
- Write the trigger condition in observable terms.
- Write the action in one sentence.
- Write the penalty for breaking it.
How it kills accounts
Rules exist → override during stress → risk increases silently → variance hits → blow-up → rebuild rules → repeat.
How it kills accounts:
- The rule exists only in your head.
- Stress arrives and you improvise.
- Improvisation becomes inconsistency.
- Inconsistency becomes random results.
- Random results become a slow bleed.
Rule that survives
Log overrides as a separate category.
If overrides don’t improve expectancy, delete them.
The fewer override types, the safer your system.
Rule that survives:
- Write the trigger in observable terms.
- Write the action in one sentence.
- Write the penalty for breaking it.
Example archetype
Your plan says ‘no trades during news’. You override because it ‘looks perfect’. It works twice. The third time it gaps and wipes a month. The override was hidden leverage.
Tell: if your rule isn’t enforceable, it’s a suggestion. Suggestions don’t survive stress.

Measure the real strategy
Your real strategy is what you do under stress, not what you wrote in calm.

Field checklist
- Write the rule in observable terms: if X, then Y.
- Remove choices under stress. Choices become rationalizations.
- Track the precursor: what state were you in before the mistake?
- Make deviations costly (size down, pause, review).
- Turn lessons into gates, not notes.
