NSE Extends Trading Hours by 10 Minutes
30 May
Summary
- NSE adds 10 minutes to equity derivatives trading hours.
- New trading hours aim to align with closing auction framework.
- Changes take effect August 3, 2026, for derivatives segment.
Starting August 3, 2026, the National Stock Exchange (NSE) will extend its trading hours for the equity derivatives segment by an additional 10 minutes, with trading now concluding at 3:40 PM. This modification is part of the NSE's implementation of a new Closing Auction Session (CAS) framework.
The CAS framework will apply to eligible cash market securities, while the derivatives market will remain open for an extra 10 minutes. This extended period ensures a smooth transition and better alignment with the updated mechanism for discovering closing prices. Stock futures will see a revised reference price introduced at 3:15 PM, with a static price band of plus or minus 3% applicable until the market closes.
While options contracts, margin requirements, and open position rules remain unchanged, traders gain valuable time to manage their positions. The NSE is introducing the CAS to enhance closing price discovery and mitigate volatility observed around market close. This new system replaces the current method of determining closing prices based on the VWAP of the final 30 minutes of trading. Furthermore, modifications to the pre-open market framework are scheduled for September 7, 2026.
