Mechanism
A limit order says: “Fill me at this price or better.” In calm markets, that’s control.
In news, price can jump through your level. You get no fill, then you chase with a market order at the worst moment. Or you do get a fill, but only because the market is moving against you (adverse selection).
Limit orders are not an anti-news helmet. They’re just a different failure mode.
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
Place limit near level → news jumps past → no fill → you chase → worse entry + worse spread → tight stop → stop-out → repeat until the day is gone.
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
Around scheduled releases: decide in advance whether you trade it or skip it.
If you trade it, accept that you cannot control fills. Use smaller size and wider stops.
If you don’t trade it, remove resting orders. Passive orders are targets.
Rule that survives:
- Write the trigger in observable terms.
- Write the action in one sentence.
- Write the penalty for breaking it.
Example archetype
You place a buy limit at support before CPI. Price gaps down through it and keeps going. You don’t get filled.
You chase to “avoid missing it,” but now your entry is worse and your stop must be tighter. You’ve converted a planned trade into a stress trade.
Tell: if your rule isn’t enforceable, it’s a suggestion. Suggestions don’t survive stress.
Deep dive
Hard rule: if you feel the urge to “just get filled,” you’re already in the wrong regime.
Glossary: adverse selection, gap, liquidity vacuum.
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.
