Exchange outage protocol requires prompt notification and coordinated extension of trading hours to enable orderly intraday position closure. Standardised operational rules define stock exchange outage and require the affected exchange to immediately notify market participants and the regulator, provide periodic updates, conduct a pre-opening session before resumption, and follow Business Continuity and Disaster Recovery protocols. Automatic, coordinated extension of trading hours across exchanges is triggered by specified timing cutoffs to permit orderly closure of intraday positions, with rules for cessation on the affected exchange if normalcy is not restored. Exchanges must adopt a uniform close-out policy and MIIs must update and board-approve their BCPs.
