- Reduce size on expiry and event sessions when structure breaks.
- Journal gap days explicitly — averages hide gap risk.
- Align structure tags with India cash session hours (9:15–15:30).
Common pitfalls
- Applying midday rules to the opening 15 minutes without adjustment.

- Over-tagging — so many structure labels that review becomes noise.
