NSE to Extend F&O Market Timings from August 3

The National Stock Exchange (NSE) has announced that the closing time for equity derivatives trading will be extended to 3:40 PM from August 3, in line with the introduction of the Closing Auction Session (CAS) in the cash market. In the first phase, the closing auction will be applicable only to stocks with derivative contracts. The closing price of all other cash market securities will continue to be determined based on the Volume Weighted Average Price (VWAP) of the last 30 minutes of trading. NSE clarified that all other trading session timings, including the pre-open session and trade modification window, will remain unchanged. The exchange has also advised brokers to update their trading systems and contract files before implementation, with testing facilities to be provided through upcoming mock trading sessions. The introduction of CAS is expected to strengthen price discovery, improve market transparency and integrity at market close, and align domestic market practices with global standards.
