London Stock Exchange ordered to sell its stake in MTS

The European Commission ordered the London Stock Exchange (LSE) to sell its 60% stake in MTS. However, the LSE said the request was "disproportionate". It warned investors it would struggle to sell MTS and that such a sale would harm its ongoing business. MTS is a relatively small part of LSE's business, but it is a major platform for trading European government bonds, particularly in Italy, where it is classified as a "systemically important regulated business". See BBC News for details.

Try MTS: Exploring the Michigan Terminal System

Try MTS is a very nice, well done, independent web site, created by Rupert Lane in June 2014. It provides information about installing and running MTS under Hercules and an introduction to using MTS. Since 2014 Lane has continued to update the site with the addition of introductions to eleven (so far) of the programing languages available in the D6.0A version of MTS: BASIC, FORTRAN, MAD (GOM), ALGOL 60, ALGOL W, LISP, UTILISP, PL/1(F), SNOBOL, RATFOR, and FLECS. The most recent updates were made in early 2016.
