CAS effect: Pre-open session rules to change from today. What changes for investors?
Economic Times 2 hrs ago·7 Sept 2026, 2:12 am
The Securities and Exchange Board of India (SEBI) has updated the rules for the pre-open trading session, which runs from 9:00 am to 9:15 am. The key change is a new time restriction on market orders. Investors will no longer be able to place market orders after 9:05 am. Instead, they must switch to limit orders to ensure their trades are executed at a specific price.
This shift is significant for traders who rely on market orders to quickly enter or exit positions. By restricting these orders to the first five minutes, the exchange aims to reduce volatility and prevent sharp price movements caused by a sudden surge in demand or supply. It ensures that the opening price is determined more fairly by the available liquidity.
Investors should be aware of this new deadline. If you prefer the speed of a market order, you must place it before 9:05 am. Otherwise, you will need to set a specific price target. Traders should also monitor the opening price closely, as the new rules may lead to wider bid-ask spreads initially.
