Quote from TimothySykes:
Sometimes I average down (or up when I'm short selling), but it's probly best that newbies don't try this because stocks can get away form you in a hurry---9 years into my trading career and some these quick moves still surprise me.
Quote from Anekdoten:
Averaging up is not averaging down when short selling.
Averaging up is when you only add to winning positions.
The term down refers to your capital and not direction.
