It doesn't really say that. Let's say you are prepared to risk 1 percent of your equity on a single pair and you break that risk down into three smaller portions of .33% risk each. You're able to average down in a way where you are still only risking 1 percent of your equity total whilst bettering your overall position.:
It's quite different from averaging since many traders do would be an interesting concept in case your system can er to it.
