India’s newly introduced closing auction session is stabilising as traders become familiar with the process, narrowing the gap between early market close and final price discovery, and aligning with global benchmark practices.
India’s new closing auction session is beginning to settle down as traders grow familiar with the mechanism designed to produce a single end-of-day price for listed shares. Sudip Bandyopadhyay told Business Today that the difference between the market’s 3:15 pm close and the final price discovered later in the session has narrowed sharply, suggesting the early turbulence is fading.
The change was introduced by the Securities and Exchange Board of India and took effect on 3 August, with the National Stock Exchange applying it first to stocks that have derivatives contracts. According to the circulars and market explainers published by SEBI and the NSE, the new process replaces the earlier volume-weighted average price method with a 20-minute auction window from 3:15 pm to 3:35 pm, intended to set a clearer and fairer closing price.
The move brings India closer to closing-price practices used in major markets worldwide, where auction sessions are common in determining benchmark end-of-day valuations. Market guides from Sahi and other analysts say the revised structure also changes how traders handle order placement and execution near the close, especially for delivery, intraday and derivatives participants.
Bandyopadhyay said the initial uncertainty should continue to diminish as investors adjust to the new timetable and pricing rules. His view is that once the process becomes routine, traders are likely to stop treating closing-auction volatility as a separate market event and simply accept it as part of the daily close.
