Bollinger Band Lathe

٢١ فبراير ٢٠١٨

Bollinger Bands shown with a horizontal basis, to make it easier to see how volatility is changing and identify squeeze opportunities.

There is a histogram (purple) which shows how the basis is changing, and a price line (yellow) showing the location of the price within the bollinger bands.

It is tuned to 2 STDEV, but shows the area within 1 STDEV a different color to help visualize when the price is near the extremes of the bands.

By default this uses an exponential moving average to calculate the bollinger basis, but this can be changed in the options.

Made it so the inner bollinger envelope multiple can be modified, and added an optional alternate calculation for stdev which uses the two-pass algorithm which I believe is more accurate than the builtin. Default options are to enable the custom stdev implementation and use EMA for the bollinger basis.

Updating to apply a scale factor while calculating the bollinger mean and deviation to increase precision with tiny cryptocurrency exchange rates.
