She nails something here - food for thought over the weekend
She said: you short and it goes up, you do not buy it and it goes up. If we rule out the horizontal move, what she is saying is that she is wrong 2 out of 3. That is why some use > 3:1. A plan could make; a winning trader better and a trader with an edge profitable. I do not think a plan would make trader with no edge profitable.
