The NSE IFSC Ltd., on October 20, 2026, has announced multiple mock trading sessions on October 24 and 25, 2026, to test system readiness and connectivity ahead of the implementation of 23.5-hour market operations.
The following has been stated:
The Exchange will conduct four mock sessions: Mock A on October 24 from 17:00 to 19:00 hrs, Mock B from October 24 at 22:00 hrs to October 25 at 00:30 hrs, Mock C on October 25 from 01:15 to 03:45 hrs, and Mock D (contingency testing) from 09:00 to 12:30 hrs. Members are encouraged to participate to test their systems and connectivity.
The mock sessions will be followed by a Live Re-login session on October 25 from 15:30 to 16:00 hrs, to avoid login-related issues on October 26.
NSE IFSC is introducing the new NEAT Adapter version NA_1.6, replacing the existing NA_1.5. The new adapter for Windows and Linux will be available from October 24, 2026, at 05:00 IST, with an interim coexistence period. NA_1.5 will be discontinued from November 28, 2026.
Trades executed during the mock sessions will not create any funds pay-in or pay-out obligations, and participants have been advised not to transfer data files for these sessions. Changes made on the Exchange CEL portal during the mock day or other Exchange holidays will be carried forward to the LIVE environment and will apply from the next trading day.
