Reference data is widely seen as the key building block in effective data management and straight through processing (STP). The London Stock Exchange's reference data products are essential, not only for the maintenance of London trading data, but through the SEDOL Masterfile's global, multi-asset database, for security masterfile maintenance worldwide.
Our reference data services are listed below.
Legal Entity Identifiers (LEI)
London Stock Exchange is an approved allocator of global LEIs. You can find our more about registering and access the global consolidated database of all LEIs on the link below.
Datasync consists of a range of services designed to provide advance notification of changes to the Exchange's trading system. This enables market participants to synchronise their trading database(s) before the market opens.
SEDOL Masterfile (SMF) provides reference data on millions of global multi-asset securities, each uniquely identified at the market level by our universal SEDOL code.
Through prompt notification of all corporate actions we enable you to keep your holdings up to date and meet clients ever-increasing demands for timely information.
As volume and velocity of trading data continue to grow, access to the right information at the right time can give you a competitive edge.
