Why it matters
Strategies often depend on regimes; using them outside their regime is negative expectancy.
Trading use: the point is not vocabulary. The point is prediction: what changes when this shows up?
Common trap
Assuming the current regime will persist.
Example
Low-vol range regime flips into high-vol trend regime.
Operational cue: if you can’t point to it on the chart, in the DOM, or in your broker logs, treat it as a story and trade smaller.
Notes
Regime awareness is a survival skill.
Quick rule
- If you see this repeatedly, you are in a different regime than your model assumes.
- Regime change usually means position size change.
- When in doubt: trade smaller, or don’t trade.
