According to the updated framework, freeze limits for other key indices—Nifty (1,800), Finnifty (1,800), Nifty Midcap Select (2,800), and Nifty Next 50 (600)—remain unchanged.
NSE has advised its members to update their trading applications by loading the revised contract file before the effective date.
The change was announced via a circular issued on August 29.
In the Futures & Options (F&O) segment, the quantity freeze limit refers to the maximum number of contracts (lots) that can be placed in a single order.
Exchanges set quantity freeze limits to ensure liquidity, promote fair play, and reduce the risk of market distortion from large, unintended trades. These limits help prevent “fat finger” errors, accidentally placed large orders that can disrupt price discovery.As per NSE’s previous circular dated June 30, 2025, the quantity freeze limit for Bank Nifty per single order was set at 600 contracts. This has now been raised to 900, effective September 1.
Expiry Day Shift for Derivatives
Starting this week, the expiry days for NSE and BSE indices will interchange. NSE has revised the expiry day for all index and stock derivatives contracts from Thursdays to Tuesdays. However, monthly, quarterly, and half-yearly contracts will continue to expire on the last Thursday of the respective expiry month.
The Nifty and stock derivative monthly contracts expired for the last time on Thursday, August 28. Revised contract files reflecting the new expiry dates are now available on the NSE website.
