This is what I got today ...

BINANCE:BTCUSDT   Bitcoin / TetherUS

maybe I'm not the first person with such a theory (relation between Fear and Greed index and BTC price) but it took time so I get it
I still didn't make sure if it can be enough useful for buying and selling or not , But I'm waiting for an opportunity to understand it .
if you agree with it , please like and comment your idea and share it with mentioning the publisher ;)
