CPI week playbook: reduced size and wider filters

CPI week playbook: reduced size and wider filters -- evergreen process.

CPI weeks are not normal grind weeks with one loud minute. Positioning, spreads, and my own attention all change for days around the print. Treating Tuesday like a random Tuesday is how I used to walk into thin books with full size.

Playbook
1. Size down from the Monday before if the print is mid-week -- not only on the day.
2. Wider go/no-go on spread; more limit preference; fewer "okayish" setups.
3. Hard blackout around the release; no heroics in the first spike.
4. Post-CPI: wait for a new balance or clear level hold before normal size.
5. Journal tag cpi_week so expectancy is not mixed with quiet weeks.

I would rather under-trade CPI week than explain a hole in the month.

How early do you throttle before CPI -- day-of only, or the whole cluster?

Post-week, I compare cpi_week tagged expectancy to normal weeks. If I kept full size and the sheet shows damage, the playbook tightens next time -- automatically, not as a mood. CPI seasonality in my behaviour is as real as CPI seasonality in volatility.
