Client and Order Identifiers

Short Code Scenarios File specifications

The client and order identifier are new requirements to introduce a unique client identifier as well as identifying orders for sponsored access and orders that are generated algorithmically. These new requirements will enhance regulatory data by increasing transparency and allowing the Regulatory Division (the "Division") to link client activity across multiple Approved Participants and Foreign Approved Participants ("Participant"), thereby improving the Division's market surveillance functions.


Status and upcoming publications

The rules introducing the client and order identifier requirements will become effective on June 28, 2024 after market close. Once the new requirements become effective, the Division recognises that Participants may need to make additional adjustments or address unforeseen challenges to fully comply with these requirements. Therefore, the Division expects compliance with these requirements no later than October 1st, 2024.

The Division intends to make additional information available through publications and encourages those who have any questions to send them by email to
