Specific Use of Indicators

Being a newbie, I am really trying to learn forex. Yes, it will take time but I am starting with the candlestick pattern. However, I am still confused about the candlestick like hammer and shooting star because they can sometimes look like the same.

To have an additional knowledge, I am trying to simultaneously include learning about 2 to 3 indicators. Can you specifically give light on what conditions these indicators work best? Appreciate if you can tell the pros and cons based on actual experience.

  1. RSI
  2. Bollinger
  3. MACD
