I think that is enough for you, and if you can learn more about that indicator, I guess you will have a chance to get the right time to buy and sell. Perhaps, you can add Bollinger Bands too as the other indicator so you can see where is the trend of the coin price. It is better to learn 3-4 indicator than to learn so many indicators because you will need a long time before you can know how to use each indicator. But that is up to you because we know what we can learn and we know how to use it properly. I am sure each of us will have their indicator that will help them to analyze the market and the coin.
