The National Stock Exchange, India’s largest bourse, is finalising plans to extend trading hours for equity derivatives, said three people with knowledge of the matter. The exchange is proposing an evening session, possibly between 6 pm and 9 pm, when market participants can continue trading futures and options contracts after the regular session between 9:15 am and 3:30 pm is over, said one of them. The NSE might consider extending this session to 11:30 pm at a later stage, the person said. Sriram Krishnan, Chief Business Development Officer, NSE speaks on market hours extension.
