The National Stock Exchange (NSE) has reduced the quantity freeze limit for Fin Nifty index derivatives to 1,200 contracts, down from the earlier 1,800. The revised limits will come into effect on December 1, the exchange said in a circular issued on Friday.
The change is based on the methodology prescribed in NSE’s F&O consolidated circular dated April 30, 2025, which guides the calculation of order size limits for various derivative products.
Under the updated framework, the maximum order sizes will now be:
-
Bank Nifty: 600 contracts
-
Nifty: 1,800 contracts
-
Fin Nifty: 1,200 contracts
-
Midcap Nifty: 2,800 contracts
-
Nifty Next 50: 600 contracts
These limits represent the highest number of contracts that can be placed in a single order by a trader.
Quantity freeze limits are a key tool used by exchanges to ensure orderly trading and avoid sudden volatility from erroneous or oversized orders. If a trader attempts to place an order larger than the prescribed limit, it is automatically rejected. Brokers can execute such large trades only by splitting them into smaller orders within the permitted ceiling.
NSE periodically revises these limits to keep them aligned with market behaviour and liquidity levels.
Separately, the exchange recently said that the number of unique trading accounts on NSE has now crossed 24 crore, less than a year after surpassing the 20-crore mark in October 2024. As of October 31, 2025, the number of unique registered investors stood at 12.2 crore, while individual investors now hold 18.75% of NSE-listed companies—touching a 22-year high.
