I suggest you use the default indicators while you are still learning about trading. You will not feel too confused to learn so many indicators available on the market. Maybe Bollinger, RSI, and MACD are good to start, but you should search for more info about using those indicators properly to benefit from that. But please remember that the indicators are only predicting where the price will move and sometimes the indicators can give a wrong prediction about the price moves. So you need to learn more about trading.
