Considering free open source R, Java, Hadoop, with direct LMAX connection for HFT with helpful links
I have been exploring various options versus my open source HFT platform with Matlab. It seems there might be some complication from a clustering point of view with expensive licensing on Matlab and Windows products. As a result, I have looked around for new options and Hadoops always popped up. Also, Matlab does not integrate too well with Hadoop so my next option was for R for analytics and prototyping. I have lots to learn with R if I go this option. I know Java so I am ok there. Java RTS could be a good option here but can always involve a C++ platform if need be but this is still undecided.
Another challenge was the broker but after seeing LMAX in UK , I was convinced that this might be the broker since they are market neutral. This might be the way to go in terms of a a high frequency trading stack. Remember this is all true open source as well which mean it is free!
Here are some links to help get you started:
Linux but will use CentOS for the distribution with Hadoop:

There are quite a few Youtube demos to show the power and quickness of this.
R with Hadoop (RHadoop):
ActiveQuant could be a good option for an API as well.NOTE I now post my TRADING ALERTS into my personal FACEBOOK ACCOUNT and TWITTER. Don't worry as I don't post stupid cat videos or what I eat!
