Sebi revises closing auction session rules for traders
In short
Sebi has changed the Closing Auction Session rules after getting more than 20,000 comments from people in the market. The new rules bring in a 10-minute closing auction, bring back the VWAP method for F&O expiry settlement prices, and clear up order-transfer rules. Most of the changes start on December 7, 2026.
This matters for stock traders and derivatives users because it changes how closing prices are set. The reporting does not say how traders will react or whether costs will rise or fall.
