Technical analysis is a very deep subject, we cannot cover enough of it in just a few posts, there are thousands of books out there that you can read and learn a lot of information, the only thing that I will say to you is that you find an author you feel comfortable with, also make an honest assessment of who you are and decide what kind of trader you want to become.
There are hundreds of indicators out there and you can apply it all to your charts but would still be wrong about the movement of the coin. The thing that you should focus on is the strategy that you are comfortable with. Consistency is the key and sticking to your own strategy would be the way to be profitable as long as you stick to it.
You can start with babypips and learn the basics for free. After that check "Charting financial markets" by Murphy, it's more comprehensive and solid material
Babypips is the best website that I can recommend to start with because it is a comprehensive website and step by step process so those who are new to trading would not be having a hard time understanding it.
