ICE: API Upgrade

Q3 2023

ICE has announced that they will undergo an API upgrade on 26th August 2023.

TT has made two changes for this ICE API upgrade which are now available in UAT for client review.

1. Exchange System ID Enhancement: TT has made the necessary changes to accommodate the extension of ICE generated system IDs. Before, these IDs were up to 9 digits long, but now they can be up to 14 digits long.

2. TVTIC Update: To reduce the risk of duplicate IDs being created, ICE has increased the length of the MiFIR Trading Venue Transaction Identification Code (“TVTIC”) from 42 characters to 51 characters by adding extra padding to the Exchange Deal ID part of the TVTIC. TT has made the necessary changes to accommodate this change.

For additional information from the exchange, please refer to the “Trading Platform API Release Notes – Q3 2023 Release”.
