Circular to intermediaries HKEX’s annual rehearsal for trading system recovery

The Hong Kong Exchanges and Clearing Limited (HKEX) will conduct its annual rehearsal for emergency trading system recovery on August 19, 2023. The rehearsal is designed to test the processes under the Hong Kong investor identification regime (HKIDR), specifically the submission of the BCAN-CID Mapping File and Reporting Forms to HKEX’s data repository and BCAN tagging for order submission to HKEX’s trading system. The rehearsal will take place from 11:00 am to 3:10 pm and is open to all Relevant Regulated Intermediaries (RRIs). Only RRIs who are Exchange Participants (EPs) are required to submit a Notification Form for Participation and a Rehearsal Evaluation Reply Form. Non-EP RRIs will not need to enroll. The aim of the rehearsal is to help RRIs become familiar with the contingency procedures and related operational matters in the event of a simulated service outage on HKEX’s systems. Additional information can be found in HKEX’s Circular from July 28, 2023.
