NSE adds 10‑minute F&O window after new cash‑market closing auction
From Aug 3, 2026 the NSE will shift the standard futures‑and‑options closing bell from 3:30 pm to 3:40 pm, adding a 10‑minute window after the new cash‑market closing auction (3:15‑3:35 pm). The change lets market participants hedge, rebalance or unwind positions as real‑time price discovery unfolds, curbing end‑day volatility.
