Alan Andrews/ action, reaction - pitchfork

Hey guys, Mike here.
Still trying to find my way here (strategy, market view). So, this weekend, I read Alan Andrews’ synopsis on median lines and such. I think it’s called the Andrews course. Very interesting.
Do any of you smart people out there have a strategy like that stuff?
Does anyone paint pitchforks?
Most of all, has anyone researched what “action, reaction” is? I see that on the charts all the time. It’s like a mirror image. If you could fold the screen in half at certain points, it just seems to match. (the chart patterns).

Just a wanderer trying to find home.
