I have noticed this pattern in the past and it seemed to work.

DISCLAIMER:
Please do not trade on this idea unless you agree with it and find more arguments for its validity.
What I'm currently doing is learning how to spot patterns properly. I need to make a few mistakes.
I like the tradingview ideas because I can see retroactively if it went well.
