Product scope: Ordinary cash equities only, 2026-11-03–2026-12-29. Includes the cash-row after-market on verified expiry dates, not every product or every day. Excludes ETFs, BDRs, options, derivatives, large-lot trades and security-specific interruptions. Preopening and closing-call accumulation are auction phases; cancellation-only windows are not executable sessions. Mon–Fri/BRT derives from jointly reviewed operational sources, not a timezone printed in the cash table.

- Historical staging note: independent candidate review and central acceptance were pending at that stage. This is not commercial or public-use permission.
- No coverage before 2026-11-03 or after 2026-12-29. The 2027-01-01 weekly expiry may roll back to 2026-12-30. Without official 2027 session evidence, December 30–31 remain unknown.
- After-market dates combine the official weekly rollback rule, listed monthly expiries and holiday closures. No single calendar directly lists all eight dates.
- Mon–Fri/BRT is an independently reviewed composite derivation. Technical connectivity hours are not trading hours.
- Historical staging note: a private central-gate trial did not itself change shared acceptance or public permissions.
