The National Stock Exchange of India Limited (NSE), on August 21, 2026, informed all members that a mock trading session for the Commodity Derivatives segment will be conducted from the Business Continuity Planning/Disaster Recovery (BCP/DR) site on August 22, 2026. The mock session will be followed by a re-login session from the Primary site to avoid login-related issues on August 24, 2026.
The mock trading session will operate from 9:00 AM to 5:00 PM, with trade modification permitted until 5:15 PM. The Primary site re-login session will be conducted from 6:30 PM to 7:00 PM. Members are not required to make changes to their NEAT Adapter settings and should retain the live-session settings as of August 21, 2026. During the mock session, operations will shift from the Primary site to the DR site through a non-graceful shutdown, requiring members to take appropriate system-level action.
All outstanding orders will be purged before trading begins from the BCP site, and members using NNF software must clear outstanding Session-1 orders before commencing BCP trading. Members should also note that for Multicast TBT, the sequence number will restart from ‘1’ when trading begins from the BCP site. Detailed operational, participation and DR switchover instructions are provided in the three annexures.
