LME has added support for Cross Orders on its platform . TT users can enter Cross Orders for LME through the Blocktrader widget . Documentation for this feature can be found here

https://library.tradingtechnologies.com/trade/blk-lme-cross-orders.html

This change is now available in TT UAT environment for users to test , and will be available in production from June 22

Important points to note for traders interested in testing this feature

1. To place Cross Orders on LME , the checkbox for "Submit Cross Orders " should be enabled . Instructions can be found here https://library.tradingtechnologies.com/user-setup/us-user-account-permissions.html
2. LME Needs to enable permissions for any user to allow them to place Cross Orders in both UAT and prod . Any user interested in trading this feature should share their COMPIDs with LME , and it will take a day roll for this change to take effect . So customers should plan accordingly
3. LME Clients need to set their OTD Profiles on TT accurately to place Cross Orders . Clients can reach out to their TT Onboarding representative for assistance with this
