Key Instructions for Members
The exchange has released a series of key guidelines to members before the upcoming mock trading session. Participants are required to upgrade their trading software to version 7.8.3 of the NEAT+ 7.8.3 version, as the previous version 7.8.2 will be terminated effective September 6, 2025.
For smooth functioning, all pending orders will be settled before every session, and members on the NNF platform have to clear any pending system orders manually. In terms of compliance, valid UCC/PAN information uploaded and cleared prior to the cut-off date alone will be allowed, although UCC validation will be waived in the case of contingency situations.
They also have to engage actively using live trading software and need to log in compulsorily in the afternoon session of September 1, 2025, to ensure readiness for live trading.
Connect2NSE and Extranet connectivity will be available throughout the mock session. But the NOTIS application will be inaccessible. The exchange also explained that all trades placed during the mock are solely for testing and will have no monetary implications. So, there will be no pay-ins or pay-outs of funds.
Support & Requests
Free toll assistance is provided on 1800-266-0050 (Option 1). Requests including Pro Enablement, conversion of dealer IDs to CTCL, password reset, Corporate Manager User ID unlock, and change of trading rights can be placed through an email providing User ID and segment information. This session is intended to assist members in validating their systems and connectivity prior to the next trading week so that they can run smoothly from Monday, September 1, 2025.
