Stock Market Timings Change: F&O Trading To Continue Till 3:40 PM, New Closing Auction Session Introduced
NDTV Profit 4 hrs ago·2 Aug 2026, 2:50 pm
Starting August 3, the Securities and Exchange Board of India (SEBI) is making a significant change to the trading day. The most notable shift is the introduction of a new Closing Auction Session. This session will run from 3:40 PM to 3:50 PM and is specifically for F&O stocks. During this time, the market will determine the official closing price for these derivatives, replacing the previous continuous trading mechanism.
For investors, this change aims to improve price discovery and reduce volatility in the final minutes of trading. By moving to a structured auction process, the market hopes to ensure that the closing price better reflects the true value of F&O contracts. Retail investors should note that the standard trading window for F&O will now end at 3:40 PM, after which they must wait for the auction to conclude.
