anybody use them? It is a free demo for corn. Otherwise monthly charges apply....seems pretty good for now that spread scope has gone under..... http://www.seasonalgo.com/ disclosure - I am not in any way affiliated with these guys, before today (I googled spread scope) I have not heard of them.
I use SeasonAlgo almost 2 years, what do you need to know? In my opinion this is the best software for seasonal and spread traders, I like that software is still in developing and that users may express an opinion what they want.
