If that guy knew the first two things about reading price action and trading in harmony with correct directrion... he would have never even considered all that average-down crap.
The fact that a major part of his approach is based on additional entries as price moves sharply against means he has no clue about how to properly trade the right direction in the first place.
No bias or opinion on my part... that's a straight-up fact. Traders who can trade price are not positioned where the market shoves itself down their throat.
As for those guys personally, no one really cares. They could all blow their accounts up and it hurts no one else. BUT... and that is a big but... they hold themselves out as educational experts while leading countless others straight down the wrong path to failure and destruction.
THAT is the one part which appalls me
