Inter-commodity ratio spreads as listed in Appendix 1 will be relisted and available for trading as of Trade Date 20 February 2024 (commencement of the night session on 19 February 2024).

The fix for the issue is a code change isolated to the Matching Engine that includes some bait calculation optimisations. Non-functional test results have shown no increase in matching engine latency and in some cases a small reduction.

What do I need to do by when?

ASX 24 trading participants and end users are advised to review and if necessary adjust their order entry and trading strategies to operate with the specified exchange provided Inter-commodity ratio spreads, UDC and Exchange Defined Combination (EDC) functionality that will be available from Monday 19 February 2024.
