The London Metals Exchange (LME) offers an electronic trading platform for the trading of all LME contracts. 

The LME are implementing a phased migration program to migrate the LMEselect platform to a new trading platform based on the HKEx Orion Trading Platform (OTP) - known as LME OTP-M.

This migration includes LMEselect FIX Market Data migrating to LMEsource multicast market data based on HKEx Orion Market Data (OMD) platform, and at a later time the LMEselect FIX 4.4 order entry API will be replaced with a FIX 5.0 SP2 order entry API.

Clients of members can connect to the LME platforms via a member using third party applications via the LME connectivity APIs supporting Order Entry, Drop Copy, and Market Data.
