BSE To Run Market “Fire Drill” With Full Scale Mock Trading On May 23

For brokers, traders and algo desks, these mock sessions are the closest thing to a market fire drill. They allow everyone to log in, place test orders, stress their own strategies and confirm that upgrades, patches or new risk parameters are working properly before the exchange goes live with any changes in production.  

What The Mock Trading Will Cover  

Because the session spans currency, commodity, equity derivatives and cash equity, participants can test almost the entire spectrum of products they use day to day. It is a chance to verify order routing, connectivity, trade confirmation, risk limits and back office flow in a controlled environment where mistakes do not cost real money but still reveal real issues.  

Why BSE Does These Drills Periodically  

Exchanges run mock trading to avoid discovering faults in live hours when liquidity, risk and reputations are all on the line. For BSE, it is also a way to align hundreds of members, vendors and algo providers around new features or changes, and to give regulators comfort that market infrastructure is being actively tested rather than taken for granted.  

How Market Participants Should Use The Day  

For serious participants, the right way to treat May 23 is not as a formality but as an opportunity. Brokers can refine disaster recovery and failover, proprietary desks can see how their algos behave under new settings, and even smaller outfits can check that all compliance, reporting and reconciliation flows work end to end.  

Mock Session Highlights  

• Mock trading to be held on May 23 across currency, commodity, equity derivatives and equity segments  
• Session aimed at testing exchange systems, connectivity and risk controls in a live like environment  
• Helps brokers and traders validate their own algo, OMS and back office readiness  
• Reduces chances of glitches when new features or changes go live on regular trading days  
• Acts as a market wide “fire drill” to keep India’s trading infrastructure resilient and reliable
