Geometric Bollinger Bands

Analogous to Bollinger bands but performs all computations on the logarithms of the values.
Unlike the regular bollinger bands (or most other variations of them available on tradingview), these won't annoy you by rescaling the chart when you try to look at the Bitcoin weekly chart or any other chart with strongly exponential behaviour, and the moving average is perfectly centered between the two bands on your log chart. The lower band is guarenteed to be positive for positive inputs.
