Impact Assessment

This update affects NSE member firms using the Order & Trade Drop Copy facility in the Capital Market segment. Members relying on drop copy data for risk management, surveillance, or back-office reconciliation must update their system configurations to use the new gateway IP and port parameters before May 11, 2026. Failure to update may result in connectivity issues or loss of drop copy data feed. The mock testing window on May 09, 2026 provides an opportunity to validate system changes before the live cutover.

Impact Justification

Technical update affecting member connectivity infrastructure for drop copy facility; operationally significant for members using the CM segment drop copy API but does not affect trading rules or listed securities.
