BSE has announced enhancements to the user interface (UI) of the RTRMS (Real-Time Risk Management System) related to the Kill Switch mechanism, as a continuation of Exchange circular Notice No. 20250930-74 dated September 30, 2025. The UI improvements aim to make it more convenient for members to access ‘Cancel’ or ‘Stop’ orders pertaining to a specific Algo ID, without altering any existing functionality.

Key Points

  • UI enhancements are being made to the RTRMS system’s Kill Switch mechanism
  • The update provides more convenience in accessing ‘Cancel’ or ‘Stop’ orders for a specific Algo ID
  • No changes to existing Kill Switch functionality are included
  • An Annexure (User Manual) is enclosed with details on the UI enhancements
  • This is a continuation of the earlier circular dated September 30, 2025 (Notice No. 20250930-74)

Regulatory Changes

No regulatory changes are introduced. This notice is an operational update to the UI layer of the existing Kill Switch mechanism mandated under the earlier circular for safer retail investor participation in algorithmic trading.

Compliance Requirements

  • Members using algorithmic trading should review the enclosed User Manual (Annexure) to familiarise themselves with the updated UI
  • No new compliance obligations are imposed; members should continue to adhere to existing Kill Switch requirements
  • For queries or clarifications, members may contact BSE at bsehelp@bseindia.com / 022-45720400/600 & 022-69158500, or iml.info@bseindia.com / 022-2272 8705/8885

Important Dates

  • Circular Date: April 27, 2026
  • Reference Circular: Notice No. 20250930-74 dated September 30, 2025
  • No specific implementation deadline is mentioned in this notice

Impact Assessment

The impact is minimal and operational in nature. Algorithmic trading members using RTRMS will benefit from improved UI convenience when managing Kill Switch actions for specific Algo IDs. Retail investors indirectly benefit from the continued enhancement of safety mechanisms in algorithmic trading. There is no market-wide or systemic impact anticipated from this update.
