I like what these guys are doing, and we tried out their plugin for modelling.
However, you can't really do any modelling without factoring transaction costs. For the average retail investor these fees kill the profit on many otherwise theoretically profitable strategies.
I'm interested in an in-depth tutorial that shows how to use the plugin to perform this kind of analysis. While I don't work in trading, I can see a lot of good uses for a tool like this while conducting other financial analysis.
