LMEselectMD will be replaced by LMEsource, the LME’s new multicast market data platform which is scheduled to launch on 21st May 2018. Please find below a high level summary of LMEsource's features and timelines, as well as the technical specifications for phase 1 of the project. To be kept aware of project developments, timelines and for further information please contact the Market Data team.
Documents for Data Vendors, Members, and ISVs relating to LMEsource testing and production can be found on the Documentation and Specifications page.
LMEsource is the new LME Market Data Platform, which is a real-time multicast market data dissemination based platform.
The first phase of LMEsource will be technically available on 21st May 2018 and will broadcast LMEselect trading data only. All market data prices and reports from all LME venues will initially remain on the existing LMEselectMD and will run in parallel with LMEsource until they are migrated at a future release.
Phase two of the platform will include all remaining datasets. The implementation dates will be confirmed in due course.
LMEsource will broadcast the LME’s latency sensitive data (i.e. LMEselect only) simultaneously; hence fair, consistent and transparent to all LME trading and market data participants.
Customisation of Market Data Products
Enables multiple multicast products to be broadcast via different channels, including a Level 1 (Best Bid and Offer) channel and a separate channel for LMEprecious products.
Uses industry standard data dissemination formats and technical protocols.
Replay and Recovery
Enables market data to be recovered if a subscriber temporarily loses connectivity, experiences network issues (i.e. dropped multicast packets), or is late to join the market.
LMEsource can only be accessed via LMEnet lines or via the Interxion London Campus Community Data Centre (CDC) for all environments. LME Market Data Vendors should contact the LME Market Data team Members and all other participants should contact the LME Technical Account Management team for further information.
LMEselectMD will run in parallel with LMEsource, the new LME Market Data Platform, until further notice. Please note that initially, LMEsource will only publish LMEselect trading data for phase one.
The test environment for LMEsource will be available from April 9, 2018. The throttles on the LMEsource in each test environment (MT-A and MT-B) will be set to ~ 5mbps (1 second interval).
Based on currently observed production traffic, with some headroom, it is recommended that participants allocate the following bandwidth for the LMEsource production service:
• LMEprecious - 30mbps of bandwidth for LMEsource when measured on a 10millisecond interval.
• LME (all other non-LMEprecious contracts) - 20mbps of bandwidth for LMEsource when measured on a 10millisecond interval.
The above quoted bandwidth is for a single LMEsource product and single feed. All participants (including Members / ISVs / Market Data Vendors) should allow additional bandwidth if planning to run LMEsource in parallel to other services including LMEselect and LMEselectMD.
If you need further guidance or have any questions related to bandwidth requirements please email email@example.com.
The technical specification for phase one is currently available from the LMEselectMD page. The phase two technical specification will be communicated in due course.
Multicast is not supported over Internet. LMEsource will only be available via LMEnet lines or via the Interxion London Campus Community Data Centre (CDC), for all environments.
No, member test environment requires an additional cross connect. It is physically separated from production CDC cross-connects. A single cross connect can be provided for member test environment. Members and all other participants should contact the LME Technical Account Management team for further information.
No, ‘Reference Data’ is only available for current business date.
‘Floor Closing price’ messages are currently not available on LMEsource. Member market data users will still need to subscribe to them from LMEselectMD after switching to LMEsource.
Bandwidth requirements will be communicated in due course which may have cost implications for users of the platform. Current market data fees are available on the website and fees relating to any new services available on LMEsource, will be communicated shortly.
