jcl,

Is there a list somewhere of all the differences between the Free Zorro and Zorro S? I am not complaining that the free version has limitations, but from a learning standpoint it would help me avoid trying to figure out features that are not included. It would also highlight all of the benefits of upgrading to Zorro S.

When I begin writing my own Zorro scripts I will need to test them and also train them, right? For testing while running a demo account on my free Zorro I assume I should wait until the weekend trading break, so I won't interrupt trading? Since I won't have the ability to train my strategies, I guess that I should just assume whatever results I get will improve after I upgrade to "S" and train them?
I recall that the training is said to improve "robustness", but not necessarily profitability. Are the robustness improvements measurable? Is there a rating or grade for it that should be a goal to achieve or maintain?

thanks,
