The bourses engaged in specific discussions with SEBI and its technical advisory panel in order to assess market infrastructure institutions' preparedness to handle any unforeseen event impacting their operations and to restore operations from the DR site within the stipulated recovery time.
Earlier, the capital market regulator had issued guidelines for exchanges and depositories to devise a business continuity plan and maintain a disaster disaster recovery site (DRS) aimed at protecting data and transaction integrity.
BSE and NSE will shift their operations from the primary site to the disaster recovery site with "a graceful shutdown at the primary site", the bourses said in separate communications to members.
"The closing price for the day shall be arrived at as per the existing rules for a normal trading day... All the outstanding orders shall be purged before the start of trading from DR site," they added.
