Assuming you mean TraderPro or whatever it's called. Top menu: Account -> Positions
I actually quite like the app. If you are a child of the modern age then sure things like Robinhood do look nice and slick, but the TraderPro app gives you everything you need in a fairly standard trader type interface.
My only major complaint is that it seems to always open a new trade window when I go to trade, even though my layout keeps the trade window in a certain spot. I would export my layout for you but I don't know how to do that.
