NSE’s pre-open session for equity derivatives goes live today. Key changes explained

The NSE has introduced a 15-minute pre-open session for equity derivatives starting December 8 to improve price discovery and ensure smoother market openings. The window runs from 9:00–9:15 AM and includes order entry, order matching, and a buffer period. It applies to current-month and near-expiry next-month futures but excludes far-month contracts, options, spreads, and corporate action–affected contracts.
