India's NSE implements nanosecond-level confirmation for derivatives orders

The National Stock Exchange of India (NSE) on Friday said that it has deployed its immediate acknowledgement feature across currency, commodity and equity derivatives.

Under the enhanced process flow, every order sent to the NSE trading system now receives an immediate acknowledgement within nanoseconds. This is a significant improvement over the previous system response time of 100 microseconds.

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.

“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,” the exchange said in a statement on Friday.

According to NSE, currently there is no other exchange in the world which gives response time in nanoseconds.

The feature, deployed as part of a new encryption mechanism, was introduced in a phased manner. It was deployed for currency derivatives in July 2025; commodity derivatives in December; and equity derivatives on Saturday.

NSE said that the real-time order acknowledgement provides members with instant visibility into order receipt, eliminating uncertainty in the order lifecycle. The new feature also enables faster decision-making and improved risk management for participants, according to the exchange.

In March, the exchange increased the maximum permissible interactive internet protocols to expand capacity for high-frequency and algorithmic trading within the NSE colocation facility.

The Indian exchange group had empaneled two fintech firms in December to provide the facility to place algorithmic trading orders with brokers, as part of the Securities Exchange Board of India’s guidelines to protect retail investors.

Chicago-based fintech Trading Technologies in February said it will leverage its platform to offer global market participants access to the NSE.
