      For example, I want to check 2 peak value of AwesomeOscillator. It is better to encapsulate the logic in a indicator class. Do we have any example to show how to make this customized class?

      Some simple questions:

      1. I don't want to cal ao again, how to fetch ao values in my indicator class?
      2. how to handle [-1] at very beginning?
      3. how do I declare define line with all values = 0
