NSE to Launch Pre-Open Session for F&O Trading from December 8

Mumbai, November 4: The National Stock Exchange (NSE) has announced that it will introduce a pre-open session for equity futures and options (F&O) from December 8, 2025. The introduction of the pre-open session will allow traders to discover opening prices for indices and equity futures before the normal trading hours.

Key Details and Timings About F&O Pre-open Session

NSE has announced that the F&O pre-open session will open at 9:00 AM and will close at 9:15 AM. It will follow a call auction format. Traders will be able to place, modify, or cancel their orders until the window closes between 9:07 AM AND 9:08 AM. After this, a price discovery and trade matching session will be conducted, which will run until 9:12 AM. Traders will be given a three minute period until 9:15 AM, after which trading hours will officially begin.

Why Does It Matters For Traders?

The introduction of the pre-open session for F&O is a welcome step for traders as it will improve price discovery for indices and futures, leading to lower volatility. The traders will be able to analyse and understand market sentiment and trend before the actual trading starts. It will also lead to better price transitions between overnight global signals and actual trading. Furthermore, it may lead to lower losses as traders will have a better idea of how the market will open before it actually does.
