Guys Laser is by far the best platform available and it will do any of the above if customized correctly. I have been using it for some time now and could not be happier. Hot Keys , reserve size, smart buys, routing, you name it. I scalp ver actively and make at least 250 trades per day. Any further info you want inbox me. If you want or have the demo I can even send you a layout that is VERY good for scalpers and I think you will be very happy, instead of making all the adjustments yourself.
This software has so many features even I get confused
