NSE slashes F&O lot size of Nifty50 contracts to 50 from 75; cuts lot size of 40 stocks

“Only the far month contract, i.e., July 2021 expiry contracts will be revised for market lots. Contracts with the maturity of May 2021 and June 2021 would continue to have the existing market lots. All subsequent contracts (i.e. July 2021 expiry and beyond) will have revised market lots,” NSE said in a circular issued on March 31.

Contracts with August 2021 weekly expiry and beyond will have revised market lots.

The day spread order book will not be available for the combination contract of June 2021 - July 2021 expiry for stocks and May 2021 - July 2021 and June 2021 - July 2021 expiries in case of Nifty50, the exchange added.

The lot size of all existing Nifty long-term options contracts having an expiry greater than three months shall be revised from 75 to 50 after the expiry of June 2021 contracts (i.e. June 25, 2021).

For the purpose of the computation, the exchange has taken the average of the closing price of underlying for one month period of March 1 to March 31, 2021.

The changes shall come into effect from April 30, 2021.
