SEBI is considering a change that would allow investors to place after-market orders during the 3:15–3:20 pm window under the closing auction call (CAS) mechanism, according to sources cited by NDTV. The proposal targets how orders can be submitted as trading transitions into the closing auction segment.

The change is intended to improve participation and support better price discovery during the CAS process, which has been newly introduced as part of market structure adjustments. Sources say SEBI is preparing the rollout of the proposed rule change, with a possible start date around September 1. The reported timeline is based on internal preparation and could be subject to further approvals and implementation steps.

While NDTV frames the move primarily as a way to broaden participation and enhance price discovery during the closing auction window, there are no additional outlet perspectives provided here to confirm other details such as operational boundaries, eligible participants, or the final regulatory wording. The proposal as described remains a plan being readied for implementation.
