Unless I am wroong on this, (selling short) means your borrow shares at say .044 then you short the position down to whatever, lets say .025, which means you know ahead of time those positions are already there and you also know that the stock will head that way, otherwise you are caught if it goes up and then you must buy anything above .044 full tilt. Otherwise you get to keep the spread. In this case the difference between .044-.025=.019/share.
Fast money without waiting.
