I am considering using it (IRIS) but am worried about brokerage fees. Who are you using to clear your trades? Do you have a recommendation? They have steered me towards Atrirum
I saw this software yesterday as well. I spoke with Ryan McKenzie on the phone. I used to do trade for an HFT firm and he answered some questions to my satisfaction, and think I will give it a whirl eventually. If you do try it can you post here how it went?
