The National Stock Exchange of India (NSE) is conducting a special mock trading session on Saturday, September 26, 2026, as part of its periodic testing of trading infrastructure and contingency arrangements. The session is not a regular market day and is intended to test systems, connectivity and disaster-recovery readiness. NSE has said such contingency drills and mock trading sessions are conducted periodically to test its trading infrastructure and recovery mechanisms.
The exercise is designed to check whether trading-related operations can continue smoothly if the exchange has to deal with a technical problem or shift operations from its primary location to a disaster-recovery site.
Why Is NSE Conducting a Saturday Test Session?
Saturday is normally a non-trading day for the regular NSE market. The September 26 exercise is therefore different from an ordinary trading session and should be viewed as a systems test rather than a normal market opening.
NSE regularly conducts mock and contingency drills so that exchange members can test their own systems and connectivity. The exchange’s disaster-recovery framework allows operations to be shifted to a secondary site if a contingency affects the primary site.
During such exercises, trading members can check their connectivity and technical arrangements while the exchange evaluates its own systems and recovery procedures.
Primary and Disaster Recovery Systems to Be Tested
The exercise includes testing of trading infrastructure and the arrangements required for a transition between the primary and disaster-recovery environments. NSE’s disaster-recovery framework covers multiple market segments and provides for a switchover if the primary site becomes unavailable.
The broader objective of these drills is to identify technical or operational gaps and ensure that members are prepared to reconnect and resume operations from the designated environment when required.
NSE’s 2026 contingency-drill calendar also confirms that the exchange conducts mock trading sessions as part of its periodic testing programme.
NSE International Exchange Also Has Testing Activity
Testing activity is also relevant to NSE International Exchange (NSE IX), where extended trading operations are already part of the exchange’s international-market framework. NSE’s international exchange at GIFT City operates for substantially longer hours than the regular domestic equity market.
The testing process is intended to examine system capabilities and operational readiness under different stages of the exercise, including procedures related to re-entry and connectivity.
Will This Affect Your Shares and Investments?
For ordinary investors, the Saturday mock session should not be treated as a normal NSE trading day. Activity during a mock session is conducted for testing and system-readiness purposes rather than representing regular market trading.
Investors should therefore not interpret activity during the test as a normal indication of market sentiment or use it as the basis for investment decisions. Regular market operations continue according to the exchange’s normal trading schedule on working days.
