REVISED QUANTITY FREEZE LIMITS FOR INDEX DERIVATIVES

The stock exchanges periodically revise the quantity freeze limits for index derivatives to ensure market stability and prevent large-scale execution errors. These dynamic limits serve as a regulatory safeguard, capping the maximum number of contracts allowed in a single order to maintain orderly trading across all major indices.

What is a Quantity Freeze Limit?

A Quantity Freeze Limit is the maximum permissible order quantity for a single trade in Futures and Options (F&O) contracts. If an order quantity exceeds this limit, it is automatically rejected by the exchange system.

The objective is to:

• Prevent fat finger trades (unintentional large order entries).
• Strengthen risk management.
• Safeguard market stability.

Previous vs. Revised Quantity Freeze Limits:

For NSE:

Note: As per the National Stock Exchange of India circular, the Nifty quantity freeze limit remains 1,800; however, with the revised lot size of 65, the effective freeze quantity becomes 1,755 (i.e., the highest divisible lot multiple below 1,800). This is only an example—other indices will follow the same methodology, where the maximum permissible lots are calculated based on the divisible lot size within the prescribed freeze quantity limit.

For BSE:

Let's see an example for better understanding:

Suppose a trader wants to place an order in Bank Nifty Futures:

The freeze limit is 900.

If the trader tries to place an order for 1,200 quantities in one go, the order will be rejected.

Instead, it needs to be split into smaller chunks (e.g., 900 quantity + 300 quantity).

Here, ICICI Direct’s Order Slicing feature comes handy. It automatically splits large orders into multiple smaller ones, ensuring smooth execution without manual intervention. With Order Slicing, traders can navigate the freeze quantity limits effortlessly and continue trading at scale, without worrying about rejections.

How Order Slicing Works?

⮚     Auto-sliced orders: For order sizes above the exchange defined limit, our algo automatically splits them into smaller, compliant slices for smoother execution.

⮚     No need to track: Just set the total quantity, slicing quantity and the time interval. Then let the algo do the rest!

⮚     Timed execution for complete control: Each slice is placed at an interval that you define, giving you full control over the pace and timing of your order execution.

Key Takeaways:

• Mandatory order splitting: Larger trades must be broken into chunks within the freeze cap.
• Market safeguard: Designed to curb errors and protect overall market stability.
