Change in Freeze Limits for Index Derivatives in Futures and Options Trading, Effective From September 1
NSE Revises Quantity Freeze Limits for Index Derivative Contracts
The National Stock Exchange (NSE) has announced a revision to the quantity freeze limits for index derivative contracts, effective from September 1, 2025. The decision aims to enhance the smooth functioning of the derivatives market and reduce the risk of 'fat finger' trades.
Under the revised framework, the quantity freeze limits for major indices have been adjusted. The limit for Bank Nifty has been increased significantly, from the previous cap of 600 to a new limit of 900. On the other hand, the limits for Nifty 50, FinNifty, Nifty Midcap Select, and Nifty Next 50 remain unchanged.
This revision directly impacts large traders in the futures and options segment, who may need to adjust their trading quantities. The NSE has advised trading members to update their systems with the revised contract details before the effective date.
To help traders get accustomed to the new order execution under the revised freeze limits, the NSE will conduct a mock trading session across market segments on August 30, 2025. The updated contract files for the revised freeze limits are available for download on the NSE's extranet server and official website.
The quantity freeze limits serve as a safety measure to prevent wrong or unusually large orders that may disturb market stability. However, the specific purpose of these limits in index derivative contracts is not explicitly stated in the provided text.
It's important to note that this change in refrigerator limits for index derivative contracts is not related to the delisting of ICICI Securities from BSE and NSE.
Traders are encouraged to familiarise themselves with the new limits and adjust their strategies accordingly to ensure a smooth transition. The NSE made the announcement regarding the change in refrigerator limits itself, emphasising its commitment to maintaining a secure and efficient trading environment.
