15 February 2011  - Migration to trading platform based on the open source operating system begins after months of delay. The London Stock Exchange has migrated its UK cash markets to a new Linux-based trading platform.

The new platform was built by Sri Lankan developer MilleniumIT, which the LSE bought in 2009. It is described as a “highly scalable, multi-asset class trading platform, offering … clients superior technical performance, ultra low-latency and enhanced functionality.”

Many financial trading systems are already based on open source software (OSS), but the LSE migration is a high profile demonstration of the viability of OSS in some of the world’s most demanding computing environments.
