Help with creating Forex EA

Hi ladies/gents! My name is Luke and I’m in the process of trying to create my first forex ea. I’m wanting to use the No Bollinger band indicator but am unable to find a way to add it. Is there anybody with EA experience that can point me in the right direction, please?
