Thinkorswim doesn't allow me to scale out (take partial profits) when I have a stop order in place. For example, if 100% of my position has a stop loss set for -1R, it won't let me sell 50% of my position at +1R. It thinks I want to short sell the stock. I have to cancel the stop loss in order to scale out. Is there a way I can sell part of my position with a full stop loss in place?
