Why did you even decide that for successful trading you need to study technical analysis? This is not the first time I have met such a statement on the forum. I get the feeling that people see in all these bars and indicators on the charts a common truth, without which success cannot be achieved.

No matter how it is. I know many people (I am also one of these people) who do not use technical analysis at all, but only use graphical analysis. For example, I only need to see levels on a 1D chart. And that's all. No moving averages and other nonsense, which, in my opinion, only clutters up the chart, I don't need it. I have been trading this way for the 4th year already.

Technical analysis is just one form of analysis, and no one needs to study it to be successful in trading.
