Impact Assessment

Impact is minimal and confined to SLBM segment members. This is a standard operational drill to test system resilience and member connectivity, including switchover to the DR site. No live trades, financial settlements, or market prices are affected. Members who do not participate may face connectivity issues on the following Monday. General investors and listed companies are unaffected.

Impact Justification

Routine mock trading session for SLBM members with no new software version; affects only member connectivity testing and does not impact live trading or listed securities.
