Updated Bollinger Bands - Custom moving average

Formula for bollinger bands is as below:
Mid = sma(20)
Top = sma(20) + 2*StdDev(20)
Bottom = sma(20) - 2*StdDev(20)
While standard bollinger bands allow changing standard deviation and length, there is no option to use different moving average.
This indicator allows you to define bollinger bands based on different moving average types which can be selected from input.

Added another type of base : dc - which stands for Donchian Channel. Instead of using moving average as base, here we are using donchian channel mid as base and applying 2 standard deviation on this to derive top and bottom.Open-source script
