I think OP is just trying to gather informations regarding to the number of people who truly believe's in TA's words.
There's nothing wrong with TA. I admire people who do that, it's just that it is Still a prediction. I'm worried that people are buying into signals. I experienced this and I didn't effectively profit just lost money.
And most of the time we could see that TA's prediction goes wrong so why bother listening to them?
Well, as we all know, it's not 100%. The important thing is risk management. That's the the critical part, IMO.
Don't wholly trust the experts? I wouldn't even partially trust them. Experts in this space are a dime a dozen, anyone who can open Twitter, TradingView and write in semi English can be an expert these days.
They could easily say that they have these profits.
Showing screenshots with green and people would believe it already. I'm not sure why they would associate themselves as experts.
The real experts have been educating people for years, and they don't make predictions. They're silently expert at their stuff, let their knowledge speak for themselves.
The humble ones are most efficient and keeping themselves with a small circle. I'm not so sure for your ”predictions” part as everyone is trying to do charts, it could be called prediction.
