Another option to look at is NinjaTrader with the 3rd party add on listed here - http://fin-alg.com/volumefootprint_gallery.html
I tried the 30 day free trial with Trade Navigator. They give you the Platinum, but as Spydertrader advice's, I purchased Gold.
I'm starting to get interested in the Gold Package. But one thing I would like to have access to of course would be the ability to automate and backtest various strategies. Darnit!!! I do want another trading platform, but I'm not sure what I should get.
