I can understand what you are saying, but I will never be a fan of technical analysis. With graphs and lines you can prove anything. But you will have people who are pro TA and people who are against.
I haven't met anyone, who can make accurate analysis and predictions based on technical analysis.
Well, i don't believe you have to make accurate predictions to be profitable in trading.
Provided you have a good win rate on a series of trades, you are good to go.
No trading method is 100% accurate. I don't even think there is any that is 90%
