Because you are teasing me about Inside Head Shoulder shit. I cannot see those on my charts. And I see you and the big hair, and know I have to shave my head soon here because it is going to get hot. Basically, I am picking on your big hair more than anything. It makes me laff.
If you are going to look through all of your instruments to find a pattern that even remotely looks like what you would call a H&S, then you are lost. In my world that I learned in, this would become a stretch W. In either case, it has zero predictive power, just like every other pattern on the planet.
I'm merely pointing out that the H&S can be found on "renko bars", if you look hard enough. BTW I merely copy/paste that chart found on the web.
