LME operates two electronic trading platforms - LMEselect and LMEbullion.
LMEselect is our electronic platform for the trading of all LME contracts. It offers a range of advanced features all tailored to the LME’s unique prompt date structure. LMEselect is the primary venue for establishing LME Unofficial Prices and LME Closing Prices.
The platform integrates with member trading platforms via a FIX API either from member sites or via data centres for the lowest latency trading strategies.
An advanced stand-alone Graphical User Interface (GUI) is also available as a management console.
LMEselect's unique ‘high-availability’ design ensures real-time data integrity across two data centres and the highest levels of service availability and reliability. Members access the full range of LME trading services from their own information systems via secure high-speed networks.
Clients can access LMEselect via member systems or member-sponsored Independent Software Vendor (ISV) platforms. In the case of member systems, client traffic must pass through a member order-routing bridge and/or a pre-trade risk engine fully controlled by the sponsoring member’s compliance team.
Client traffic can also pass through an ISV pre-trade risk engine endorsed and controlled by the sponsoring member's compliance team.
Enquiries about trading through the Select API should in the first instance be directed to your trading member.
Latency-sensitive clients of members can now access data from the electronic order book directly, as well as via licensed data distributors and or members. For information on how to access data from LMEselect directly please email us.
