Extremely powerful and unique tool Extremely powerful and unique tool. Im not aware of any other like it on the market.

Once you get used to systematically investing with a model you will wonder how you did it any other way (or how you could do it any other way). The staff is extremely knowledgable and responsive. The user community is generous and supportive. Beyond that, the tool is just fun to research, test theories and play around with.
