Multi Band Channel

Putting multiple bollinger bands/keltener channels together helps visualize the relative price movement. I have also used this in my BuyTheDip V2 strategy to measure dip and bounce back. 7 Standard deviation is used here. These are calculated based on the input fields StdDevStart and StdDevStep.
