The Bombay Stock Exchange (BSE), on September 10, 2026, notified trading members that a mock trading session for the Equity Derivatives segment will be conducted on Saturday, September 12, 2026, from both the Primary Site (PR) and Disaster Recovery Site (DR). Members using third-party trading platforms or in-house systems through ETI APIs may use the session to test various trading functionalities, including risk-reduction mode and trading halt. No new BOLT TWS release will be introduced.
The login window is from 9:15 AM to 10:00 AM. At the Primary Site, the pre-open session runs from 10:00 AM to 10:15 AM, followed by continuous trading from 10:15 AM to 12:00 PM. After the switchover to DR from 12:00 PM to 12:45 PM, the DR pre-open runs from 12:45 PM to 1:00 PM, followed by continuous trading from 1:00 PM to 2:55 PM. Future contract price bands will also be updated for alignment with the CAS in the Equity Segment, and trade modification is scheduled at 3:25 PM.
The mock trading is solely for testing and familiarisation. Trades executed during the session will not attract margin, pay-in or pay-out obligations and will not create any rights or liabilities. Participants are requested to actively participate and provide feedback to the Exchange by 4:00 PM.
