Just eyeballing it's difficult to say if there is an inverse correlation or not. Other than the period from Oct/17 through Jun/2018 they haven't moved together all that much.
So the S&P is useless as a twitter trading signal.

It's amazing how much you can learn visually. I guess that is how my brain works. As an artist (Viewing TA as an art but also someone who studied art among other subjects.) I always try and explain things visually. It's often easier than the alternative.
As some of you know I've been presented with some unique challenges in my personal life. I try and remain on topic but I get distracted at times.
Plus the feeling of wanting to explain myself to people I meet and others. It's annoying. But that's life.
Anyway, for those of you out there creating. Keep doing what you do. As long as you maintain a clear intent I don't mind the absurdism because life is absurd. (Except for that one b****.) In which case please stop.
Harassment is not ok. I don't care who you are or how right you think you are.
Treat eachother with respect and life is better for everyone. Happy trading.
