I do not use m$oft windows, and I have been using only linux. Most of the trading s/w like tradestation, ninjatrader only works in windows, and that leaves me out. I don't want to maintain a windows system, since that makes me very nervous, with respect to viruses etc. I am thinking of running ninjatrader on a windows 7 image on Amazon AWS. I don't know what other problems I'll run into. I also live in a pretty rural area where DSL bandwidth is not that great. Has anyone here, have such an experience ? what do ya think ? regards, -br
