Improvements

Exchanges

TT has added support for the optional field of Liquidity Provider ID, that has been introduced by Euronext, on the order messages. This field will be available for configuration on TTUS under account settings.
FIX users can use FIX parties block Tag 448 for specifying this ID, with Tag 452 = 35.

Note that the existing field of LP Role will be set as 1 (Liquidity Provider and Market Maker) by TT, when the Account Type is specified as Market Maker, as that is the only value allowed by Euronext on the derivatives market. No value needs to be specified by customers for the LP Role field.
The Liquidity Provider ID field is now available in the TT UAT environment for customer testing.
