HFT backtesting potential with some open source stock market simulator options A couple in Java and one in Objective C

HFT backtesting potential with some open source stock market simulator options A couple in Java and one in Objective C

These are rather interesting. I don’t want to blow any cash yet on market feeds so I thought this would be an option. There seem to be 3 open source projects for this but Jessx looks the most promising. I have seen something similar at Rotman which is part of University of Toronto. I was blown away by its sophistication. Jessx looks similar so I may try it. I would I could have open source trading platform connect to simulate trade against but Jessx only serves up XML messaging. The Webcurvesim does output FIX so that may be an option as well.  Swarm is not good option as it is in Objective C and needs to be in a MINGW which  I am not a fan of. Let me see how this goes.

Here are the options:

Is Apple iPhone and Objective C development dying? Objective C and Google Go dropped off in Nov 2010 in popular programming

Is Apple iPhone and Objective C development dying? Objective C and Google Go dropped off in Nov 2010 in popular programming

Please explain this:

After having been the rising star for a long time now, Objective-C dropped considerably last month. The ratings for Objective-C are 0.5% less if compared to October. Other remarkable changes in the TIOBE index this month are the first time entrance of Lego’s Mindstorms programming language NXT-G in the top 20, the sudden decline of Google’s Go (out of the top 20) and the lowest position for Visual Basic ever since the start of the index.
