NSE rolls out nanosecond level acknowledgement for market orders from April 11
The National Stock Exchange of India (NSE), the world’s largest derivatives exchange by volume, has deployed its Immediate Acknowledgement feature across Currency Derivatives, Commodity Derivatives, Cash (Capital Market), and Equity Derivatives from April 11, delivering order acknowledgement in nanoseconds for median and mean observations, a significant improvement over the previous system response time of 100 microseconds.
“This milestone represents a transformative upgrade to NSE’s trading infrastructure, reinforcing India’s position at the forefront of global exchange technology and furthering the Exchange’s commitment to building a transparent, efficient, and world-class capital markets ecosystem,” NSE said in its press release.
NSE further said that under the enhanced process flow, every order sent to the NSE trading system now receives an immediate acknowledgement within nanoseconds. This real-time receipt confirmation is followed by the standard processing and confirmation or rejection message, ensuring that market participants can track order receipt instantaneously, with dramatically improved certainty and transparency. Currently, there is no other exchange in the world who is claiming to be giving response time in nanoseconds.
The exchange said the new immediate acknowledgement feature was introduced in a phased manner. The new feature for Currency Derivatives came into effect on July 1, 2025, and for Commodity Derivatives, it was deployed on December 13, 2025. The immediate acknowledgement feature for Capital markets/ equities and Equity Derivatives will come into effect from April 11.
NSE further noted that the advanced feature is a first in the world, and it will help enhance market transparency by providing Real-time order acknowledgement, which provides members with instant visibility into order receipt, eliminating uncertainty in the order lifecycle.
