An NSE page that still shows the old day
NSE’s general Market Timings page, read on 2026-10-12, still listed these rows for equities:
Rows as shown on that page on 2026-10-12.
| Trading session | Time |
|---|---|
| Pre-open session (Regular) Close | 09:08 hrs |
| Normal / Odd lot market Close | 15:30 hrs |
| Closing session Open | 15:40 hrs |
| Closing session Close | 16:00 hrs |
In plain words
The 09:08 pre-open close is the time in the “Current Time” column of NSE’s pre-open FAQ table, which the FAQ revises from 7 September 2026, and the 15:40–16:00 closing session does not appear in the closing auction page’s schedule, which ends the day with a post-close session from 3:50 to 4:00 pm. NSE’s FAQ states that where it differs from the circulars, the circulars are final; this site follows the circulars and the FAQ and product page that match them.
