Looks good, very similar to booktrader with IB, but lacking key features like customizable buttons for "up 1 tick", "up 4 tick", etc.
No sign of "reverse trade" button either?
I would take the 1 month free trial, and if it helps you make money then go for it, if not, then forget it!
Hard to beat IB's booktrader - has everything you need for scalping.
