Sunday, November 30, 2025

30/11/25, The National Stock Exchange (NSE) has issued a new circular announcing revised quantity freeze limits for index futures and options. The updated limits will come into effect from December 1st and apply to major benchmark indices such as Bank Nifty, Nifty, Fin Nifty, Midcap Nifty, and Sensex.

 

The update is expected to improve market stability and prevent erroneous large orders in the derivatives segment.

According to the circular issued on November 28, 2025, under the reference NSE/FAOP/71540 (Circular No. 203/2025), the exchange has updated the maximum order size that traders can place in a single transaction for index-based contracts.

What Are the New Quantity Freeze Limits?

As per the NSE circular, the revised limits for index F&O contracts are:

Bank Nifty: 1,800

Nifty: 3,600

Finifty: 1,800

Midcapnifty: 900

Sensex: 1,000

These limits restrict the maximum number of lots a trader can execute in a single order, ensuring price stability and reducing the possibility of fat-finger trades.

Why NSE Updates Quantity Freeze Limits

The NSE periodically reviews and adjusts these limits based on market volatility, trading volumes, and the overall risk environment. By tightening or revising these thresholds, the exchange aims to prevent abnormal impact due to large single orders, maintain liquidity balance, enhance risk management in the derivatives segment, and ensure smoother order execution for retail and institutional investors.

The latest update aligns with the exchange's commitment to improving transparency and safety across the F&O market.

Impact on F&O Traders and Market Participants.

For traders, especially high-frequency and institutional participants, the updated index quantity freeze limits mean they must break up orders into smaller chunks. While this may slightly increase execution time for very large positions, it significantly reduces the chances of slippages and accidental oversized trades.

Retail traders may not be affected significantly, as most individual F&O positions usually stay within these thresholds.

The update also ensures that trading systems, brokers, and algo platforms remain compliant with the revised rules by December 6, 2025. NSE has advised all members to update their trading applications and refer to the NSE_FO_contract_dissemination.csv file for fresh contract data.

Where to Check the Updated F&O Contract Details

NSE has asked brokers, traders, and market participants to download the latest contract-related information from:

Step 1: Go to the NSE's official website.

Step 2: Select products, then go to the Derivatives section.

Step 3: Select the Futures & Options

Step 4: Select Contract Specifications
