Whatever the method you use, you are trying to find a system that identifies the patterns in the market so you can make an educated guess about the outcome of your trades. Irrespective of the method, learning (through trading) trains your brain to identify these patterns.
Think of different trading methods as different languages. We grow up learning different languages depending on our mother tongue and location. Just as a person’s intelligence does not depend on the language he uses, your innate ability to identify these patterns does not depend on the method you use. But whatever the method you choose, stick with it for long enough so you’ll understand how everything works. Trying to learn a new language every week will take you nowhere!
Personally, I feel you should start with price action trading. It will help you understand the dynamics of the market. Once you get a strong grip on the fundamentals, you can use whatever the alternative method you think will help you with your strategies. Essentially all these alternative methods have the same purpose. They cram the market information over a given period into easily identifiable patterns or numbers(in the case of indicators).
Be informed that this post only addresses the intellectual side of trading. You should also learn to master the other major component of successful trading i.e., emotional discipline.
