HKEX has announced enhancements to improve the Block Trade workflow for a tentative Go Live in Q3 2023.

It has come to TT’s attention that Members have been asked to “confirm that all of your OAPI programs are capable of handling the new Session State on or before Aug 4, 2023.” Members should feel comfortable submitting this confirmation at any time, but should also feel free to confirm this first-hand using the UAT Environment.

For all other enhancements other than “Block Trade Order Entry after the Close of T Session,” it has been verified that there is no impact to the TT Platform. Customers should follow the instructions provided by the exchange for those three enhancements.

  • Lower MVT for HSI and HSCEI Back Month Contracts
  • Enhanced Block Trade Price Precision by Average Pricing
  • Block Trade Order Entry after the Close of T Session
