NSE Revises Quantity Freeze Limits for Fin Nifty: What You Need to Know?

The National Stock Exchange (NSE) has adjusted the quantity freeze limits for Fin Nifty index derivatives, with the new limits coming into effect on December 1, 2025. The freeze limit for Fin Nifty has been reduced from 1,800 to 1,200 contracts. According to a circular issued on Friday, the revisions follow the methodology outlined in the F&O consolidated circular dated April 30, 2025.

Updated Quantity Freeze Limits Across Indices

The revised limits, which cap the maximum permissible size of a single order to avoid erroneous trades, are as follows:

• Bank Nifty: 600
• Nifty: 1,800
• Fin Nifty: 1,200
• Midcap Nifty: 2,800
• Nifty Next 50: 600

These limits help ensure that unusually large orders do not enter the system and impact market stability.

Purpose of Quantity Freeze Limits

Exchanges periodically revise quantity freeze limits to enhance market safety. These thresholds act as a protective mechanism against “fat finger” errors—accidental oversized trades that can distort prices or trigger volatility. By imposing maximum order sizes, the exchange aims to promote orderly and stable trading in futures and options contracts.

How Orders Above Limits Are Executed?

If a trader attempts to place an order exceeding the exchange’s prescribed limit, the system automatically rejects it. However, brokers may split such orders into smaller chunks to comply with the freeze limits, allowing them to be executed without breaching the rules.
