The Multi Commodity Exchange of India Limited (MCX) on April 11, 2026, issued advisory Review of existing CTCL Approved Software.
The circular issued by Multi Commodity Exchange of India reiterates requirements for Trading Members regarding testing, approval, and maintenance of trading software applications such as CTCL, IBT, WT, DMA, and Algo systems. Members must ensure that all in-house or vendor-provided applications are thoroughly tested in the Exchange’s mock/simulation environment and obtain prior approval before deploying them in the live production environment. Additionally, any updates or modifications to these applications must also be re-approved by the Exchange.
The Exchange has emphasized the need for continuous and rigorous testing of these systems in the mock environment to ensure stability and compliance. This is crucial as software applications may undergo periodic changes, and maintaining updated, approved versions helps prevent operational and compliance risks.
Further, Trading Members are advised to conduct a comprehensive review of all approved applications and identify systems that are obsolete, unused, or unsupported. Such applications should be deactivated to ensure that only relevant and active systems remain registered with the Exchange, aligning with current business and operational requirements.
For deactivation, members must follow a defined process: first, raise a request on the eUIMS portal to deactivate the relevant facility (CTCL/IBT/WT/DMA/Algo) from the user ID, and then submit Annexure 43 (as per the earlier circular) via email to the Exchange. Members are advised to take note and ensure compliance with these guidelines.
