Impact Assessment

Operational Impact: Medium - All trading members must upgrade their systems and participate in mock trading to ensure smooth transition. The mock session provides comprehensive testing of both primary and DR site operations.

Market Impact: Low - This is a scheduled mock trading session with no real financial obligations. Trading schedules include pre-open, normal market, T+0 market, block deal windows, auction sessions, and contingency operations.

Technical Impact: Medium - Members need to coordinate system upgrades, test connectivity, and ensure compatibility with the new NEAT+ version. The mock session tests various trading modes including special pre-open sessions, call auction for illiquid securities, and DR site switchover procedures.

Timeline: Members have approximately one month (until November 01, 2025) to complete the transition from NEAT+ 7.8.3 to 7.8.4.

Impact Justification

Mandatory system upgrade affecting all trading members; requires preparation and testing but is routine infrastructure maintenance with clear timeline
