The feature, which will go live for cash and equity derivatives segments from April 11, ensures that every order sent to the exchange is acknowledged almost instantly — within nanoseconds — compared with the earlier response time of about 100 microseconds.
The upgrade is part of a broader system enhancement that has already been implemented in a phased manner across segments. Currency derivatives adopted the feature in July 2025, followed by commodity derivatives in December 2025, with the final rollout now covering capital markets and equity derivatives.
Under the new framework, traders receive immediate confirmation that their orders have reached the exchange system, even before final processing or execution status is communicated. This reduces uncertainty in the order lifecycle and allows market participants to track transactions in real time with greater precision.
The exchange said the enhancement has been built using a new encryption mechanism and includes a transition phase to allow brokers and members to migrate smoothly from the existing system without disrupting live trading.
The move positions NSE at the forefront of exchange technology globally. According to the exchange, there are currently no other markets claiming nanosecond-level response times for order acknowledgement, underscoring the scale of the upgrade.Beyond speed, the change is expected to improve operational confidence for traders and institutions. Instant acknowledgement of orders enables faster decision-making, better risk management and clearer visibility into market activity, particularly in high-frequency trading environments.The development comes as exchanges globally continue to compete on latency, system reliability and execution quality. For NSE, which is already the world’s largest derivatives exchange by volume, the upgrade reinforces its focus on technology-led market infrastructure and maintaining competitive parity with global peers.
