Mechanism
Margin mechanics don’t negotiate. When equity falls and margin requirements rise, positions are closed automatically or under duress.
Forced liquidation creates feedback loops: selling pushes price down, which triggers more selling.
This is why leverage is not just faster returns; it is fragility.
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
Overleverage → drawdown → margin requirement rises → forced close → bad fills → deeper drawdown → account death.
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
Structure so you are never forced.
Keep margin buffers that assume spreads widen and fills worsen.
If liquidation is possible, your primary strategy is “eventually forced.”
Rule that survives:
- Write the trigger in observable terms.
- Write the action in one sentence.
- Write the penalty for breaking it.
Example archetype
A gap hits, your stop fills worse, margin spikes, broker closes positions at the bottom. You didn’t lose the argument. You lost the right to argue.
Tell: if your rule isn’t enforceable, it’s a suggestion. Suggestions don’t survive stress.
Deep dive
Solvency is a strategy
Survival is not conservative. Survival is how you stay in the game long enough for edge to compound.
Glossary: margin, liquidation.
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.
