The LME currently offers its members two order management applications, running in parallel:


The original electronic member to member trading system, providing access to all LME contracts - futures, options and TAPOs, as well as pre-trade risk management (PTRM) functionality.

The available connectivity options to LMEselect in production are via LMEnet or CDC. In member test, LMEselect can be accessed via the internet, LMEnet or CDC.


The new web-based platform launched in January 2023, providing access to LME futures contracts.

The available connectivity options to LMEtrader in production and member test are via the internet.

Both platforms can be accessed by membership categories 1, 2, 3 & 4, allowing members to anonymously execute trades with other member firms.

Tradable hours are 01.00-19.00, Monday-Friday (London time) with pre-trade and post-trade periods 00.45-01.00 and 19.00-19.30 respectively.

LMEselect and LMEtrader benefit from straight through processing efficiencies where trades are automatically sent to the matching and clearing systems - LMEsmart and the LME Clear system (LMEmercury). 

Clients of members can connect to LMEselect via a member using third party applications via FIX API protocol. FIX applications are developed by members internally or via an Independent Software Vendor (ISV).
