On August 4, LME Select will introduce production support for trade-at-settlement (“TAS”) functionality. As part of the roll out, the LME intends to re-enable TAS (price code “TC” Trade at Close) for 3-month Nickel, and launch TAS on the 3-month contracts for Aluminium, Copper, Zinc, Lead and Tin. These products are now available for testing in the TT UAT environment. In Production, the products will be visible, but in HALT state as of July 26, and trading will begin after August 4. The product codes will be listed on TT as follows: 1. Aluminium - AHDF 3M TC
2. Zinc - ZSDF 3M TC
3. Copper - CADF 3M TC
4. Lead - PBDF 3M TC
5. Tin - SNDF 3M TC
6. Nickel - NIDF 3M TC Note: Should a user observe a discrepancy in the tick size of these products, the following steps should be followed in order to resolve the issue in TTW: Step 1: In the TT Workspace, Click on Edit --> Preferences

FIX Services
For customers whose FIX engine natively supports SSL encryption, or who have implemented FIX session encryption using STunnel with certificate pinning, TT provides a TTFIX.crt file with the public certificates used by the TT platform FIX endpoint. These certificates expire on an annual basis and must periodically be refreshed to continue functioning. On June 13, 2025, TT updated the stunnel.zip file located in the Download Center in order to update the soon-to-be-expired certs in the TTFIX.crt bundle. All TT customers who use STunnel must download the new zip file and apply it at any time before the new zip file update is applied in each TT environment, which will be:
>> June 20, 2025 for UAT
>> June 27, 2025 for SIM
>> July 11, 2025 for Production - New York
>> July 18, 2025 for Production - All other locations Customers still using the old stunnel.zip file after the dates listed above will not be able to connect to the respective TT environments. Added TT Platform STAR.TRADE.TT; valid from 2025/06/01- 2026/06/01 Additional Resources:
