In an important update for trading members, the National Stock Exchange of India Limited (NSE) has announced a deferral in the release of its much-anticipated NEAT Adapter Version 1.0.21. Through Circular dated July 5, 2025, the Exchange has clarified that members are to continue using the existing version—NEAT Adapter 1.0.20—until further notice.
This update is especially relevant for those operating in the Currency Derivatives (CD) segment, as it includes critical instructions regarding the port configuration that members must use from Monday, July 07, 2025.
What Is the NEAT Adapter?
The NEAT (National Exchange for Automated Trading) Adapter is a software interface used by trading members to connect their trading systems with NSE’s core trading platform. It facilitates seamless trade execution, data dissemination, and connectivity between members’ front-end systems and the Exchange’s trading engine. NEAT Adapters are periodically updated to improve performance, security, and compatibility with new features and regulatory changes.
The key points of the current circular are:
Postponement of NEAT Adapter Version 1.0.21:
The release of Version 1.0.21 has been delayed.
No new launch date has been communicated yet.
Members are advised to await further notification from the Exchange regarding its availability.
Continued Use of Version 1.0.20:
Members are instructed to continue operations using NEAT Adapter Version 1.0.20.
This version remains fully functional and compatible with the CD segment’s trading requirements.
Port Configuration for Currency Derivatives Segment:
Members must use port 10877 to access the Currency Derivatives segment.
This configuration will be effective starting Monday, July 07, 2025.
What Does This Mean for Trading Members?
For members of the NSE, particularly those participating in the Currency Derivatives segment, this circular ensures continuity and stability in operations. The postponement allows firms to continue with their existing systems without any immediate need for adaptation or testing of new software versions.
However, members should:
Refrain from making any changes expecting the release of Version 1.0.21.
Ensure their trading infrastructure is aligned with Version 1.0.20 and is correctly configured for port 10877.
Stay alert for future circulars or notifications from NSE regarding the new version’s revised release date.
