# Closing Auction Raises Delivery Risk for Stock Option Traders 2026-08-06T14:51:42+00:00 | Business & Economy | Indian Opinion Desk Corroboration: 1 independent outlet The new closing auction window could leave stock option traders with unexpected delivery obligations when monthly contracts expire, Livemint reports. The official settlement price is determined after order matching ends, so an option can shift from out of the money to in the money during the final auction. NSE and BSE monthly expiries on 25 and 27 August will be the first key tests. Continuous trading ends at 3:15 pm, followed by order matching between 3:20 pm and 3:30 pm. Traders can use the 3:30 pm to 3:40 pm post-close window to square off. Those unable to deliver shares may face auction premiums of around 1% to 2%, plus a 1% facilitation fee. Index derivatives are cash-settled and are not affected. ## Coverage - livemint.com Tags: BSE, closing auction, NSE, options trading, stock markets Canonical: https://indianopinion.org/closing-auction-raises-delivery-risk-for-stock-option-traders/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
