This is a more advanced version of the standard Bollinger Bands indicator. It allows you to change the type of the moving average (Simple, Exponential, Weighted, Volume-weighted, Triple EMA or a moving average that uses RSI ). The indicator also allows you to volume weight the indicator (turned on by default). If you want to weight the oscillator against the true range instead of volume this is also possible. By default, this will be done automatically for assets that do not support volume .
