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.
Even when you do the technical analysis, you still can't guarantee a sure win for every trades. That's why there is a stop-loss if incase your analysis goes wrong, the cutting loss is very important in trading, it's one of the best weapons in trading because of NO 100% TRADE every time.
I'd rather use technical analysis than fundamental analysis, that's why if you want to become a trader you should really learn and love technical analysis.
