The Johannesburg Stock Exchange (JSE) has announced that it is moving to an all Linux based trading platform when it relocates to Johannesburg. The JSE currently operates out of London and runs on the TradElect platform which is based on Microsoft .Net and SQL Server 2000. It plans to move to MilleniumIT's Millennium Exchange platform by the first half of 2012.
