Impact Assessment

This circular has low market impact as it pertains to a scheduled mock/test session with no financial settlement, no new software release, and no changes to trading rules or regulations. The primary operational impact is on SLBM segment members who must participate in the mock session and confirm live re-login to ensure smooth Monday operations. Temporary unavailability of Connect2NSE, Extranet, and NOTIS during specified windows should be planned for by technology teams.

Impact Justification

Routine mock trading session for SLBM members with no financial obligations, no new software version, and no regulatory changes. Primarily an operational readiness exercise ahead of Monday live trading on April 13, 2026.
