Steps
Hold a leveraged position into rollover.
Liquidity thins; spreads widen around roll.
Price gaps or prints a spike.
Mark-to-market worsens instantly due to bid/ask.
Margin level drops; stop-out threshold approaches.
Broker liquidates positions to protect themselves.
You realize loss at worst time.
You re-enter to 'make it back' and repeat.
Intervention points:
- Cut size at the first sign the chain is forming.
- Pause when you start “fixing” the last loss with a new trade.
- Stop trading when execution quality degrades.
Antidote
Avoid holding high leverage through roll windows.
If you must hold, keep a large margin buffer and reduce size ahead of roll.
Treat financing + rollover microstructure as part of the thesis.
- Stop the sequence: one loss is information, two losses is a warning, three losses is a system failure. Have a hard cut.
- Reduce degrees of freedom: fewer pairs, fewer timeframes, fewer discretionary choices.
- Re-enter only after reset: calm state, checklist passed, size reduced.
Notes
Many traders blame ‘mystery spikes’. Often it’s rollover + thin liquidity + leverage.

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.
