Notice reference number: 1156.23.11
Date published: 08/11/23
Effective as of: 08/11/23
Last updated: 08/11/23

ASX recently identified a technical issue that could impact the execution of User Defined Combination (UDC) orders on the ASX 24 market, as detailed in notice 1143.23.11. As a precaution, the creation of UDC instruments has been temporarily disabled. In response to this, clients within the electricity market have expressed concern around the inability to execute combination trades where Exchange Defined Combinations (EDC) do not exist.

As an interim solution, ASX is lowering the minimum volume threshold to 1 lot on Block Trades (subject to a number of conditions) across Australian and New Zealand Electricity spreads that cannot be executed via an Exchange Defined Combination. This will allow Market Participants to continue to execute strategy orders without the associated legging risk. To support this, a temporary change to Procedure 4820 will take effect immediately and remain in place until further notice. A marked up version of the Procedure is attached.
