The National Stock Exchange of India has altered its pre-open session rules, effective from September 7, 2026. During the session, which runs from 9:00 am to 9:15 am, investors can place market orders for five minutes, between 9:00 am and 9:05 am. From 9:05 am to 9:10 am, only limit orders can be submitted, as market orders are prohibited during this period.
The exchange will match limit orders from 9:10 am to 9:12 am, determining the opening price. Previously, the matching process occurred from 9:08 am to 9:12 am, but now it begins at 9:10 am. The last three minutes, from 9:12 am to 9:15 am, serve as a buffer period before regular continuous trading commences. The revised framework applies to all eligible securities in the equity cash market's pre-open session, including mainboard and SME shares, partly paid-up shares, Infrastructure Investment Trusts, and Real Estate Investment Trusts.
NSE made these changes to align the pre-open mechanism with the Closing Auction Session, introduced on August 4, aiming to enhance coordination between the cash and derivatives segments.
