Synopsis

The National Stock Exchange (NSE) will extend equity derivatives trading hours by 10 minutes, with the market now closing at 3:40 pm, effective August 3, 2026. Pre-open and normal market opening times remain unchanged. The volume-weighted average price for closing prices will still be based on the last half-hour of trading.

The National Stock Exchange (NSE) has extended trading hours for the equity derivatives segment by 10 minutes, with the normal market closing time revised to 3:40 pm from the current 3:30 pm. The change will come into effect from August 3, 2026.

According to an NSE circular, the pre-open session timings in the derivatives segment will remain unchanged, with trading beginning at 9:00 am and the pre-open session ending at 9:08 am through a system-driven random closure in the final minute. The normal market session will continue to open at 9:15 am.

The trade modification window will also remain unchanged and will continue until 4:15 pm.

There will be no change in the methodology used for computing closing prices of derivative contracts. NSE said the volume-weighted average price used for close price calculation will continue to be based on trades executed during the last half hour of trading, which will now be from 3:10 pm to 3:40 pm.

The exchange added that the functional changes arising from the implementation will be made available for testing during mock trading sessions. A separate circular detailing the mock sessions will be issued later.

The exchange will also broadcast a message on NEAT trading terminals at the start of the Closing Auction Session in the equity segment when the operating price range for stock futures is reset. As part of the process, outstanding orders lying outside the revised price range will be cancelled by the exchange in accordance with existing rules.
