Impact Assessment

Operational Impact: Medium - All equity trading members must participate and configure systems for DR connectivity. Requires technical preparation and testing of backup infrastructure.

Market Impact: Low - Mock trading session on Saturday (non-trading day) with no impact on regular market operations.

Technical Requirements: Trading members must have technical teams available to modify connection parameters across multiple systems including BOLT TWS, third-party applications, and web-based platforms. Members using leased line and internet connectivity both need to update configurations.

Business Continuity: This exercise validates BSE’s disaster recovery capabilities and ensures trading members can seamlessly switch to DR infrastructure in case of primary site failure, strengthening overall market resilience.

Impact Justification

Mandatory participation in DR mock trading session affects all trading members but is routine infrastructure testing with no market impact
