Thanks everyone!
...except for the, apparently legendary, numbskull who thinks the question wasn't clear.
So, it sounds like nobody really knows anything, it just seems like cheating to get signals (if they worked). And, anecdotally people hear that others who try them don't fare well... so they don't work.
Hmm.
I was so excited to get started coding up trading strategies and signals in tradingview using pinescript. It looks like it may even be possible to connect these things with machine learning to create a sort of AI based strategy. Exciting stuff, but I'm only beginning to learn about it all.
I hope it's not morally objectionable to try to program strategies that can give indicators. I mean, if we can't use math and science to make sense of nature, then what is it for?
Maybe there's some confusion about people thinking that these strategies would or could ever work 100% of the time. I hear anything over 60% or maybe even less means it's profitable. The idea is to build one that can predict better.
I get what you're saying though. Nobody has been able to create indicators that work reliably. But, that's a bit YET, right? And, you guys wouldn't be mad at a coder for trying would you?
