Does This Exist – Technology

I have been creating a small infrastructure stack on and off this week on one of my Linux boxes to bring all of my infrastructure into a private cloud capable of looking after personal affairs and some business affairs as well. So far I have document management, file management, WordPress management, email and good few other items sorted. All of this kit is free open source software licensed under GPL and runs nicely on one of my web servers. However one nice to have piece of kit is alluding me. What I am after is a free platform for Forex trading and stock market information. Does this even exist? Google and SourceForge have not been much use so far. So my big question is does the stuff I am after actually exist? Many thanks in advance to all!
