Trading hours, holidays and market states
When Indian markets are open, what pre-open does, and what Live, Delayed, Stale and Closed mean on the site.
NSE and BSE cash markets trade Monday to Friday, 9:15 am to 3:30 pm IST, with a pre-open call auction from 9:00 to 9:15 that sets the opening price. Exchanges are shut on weekends and on declared holidays.
What the badges on the site mean
Every quote on Market Intelligence carries an as-of time and a state:
- Live: the provider states zero delay.
- Delayed: the provider states a delay, shown in minutes.
- Stale: the last value is older than the freshness limit; treat with caution.
- Closed: outside the session, so you see the last close and the next session.
- Unavailable: the feed failed; the page says so instead of guessing.
End-of-day data
The scanner, backtests and most macro series update after the close or on the source's release schedule. A reading from yesterday is not a live signal.
Key takeaways
- Cash market: 9:15 am to 3:30 pm IST, Monday to Friday.
- Always check the as-of time and state badge before acting on a number.
- Missing data is shown as unavailable, never silently estimated.
