This shows centered on a horizontal basis, to make it easier to see how is changing and identify squeeze opportunities. By default are calculated using an and an improved higher precision stdev implementation, but this can be disabled. Version 2 also shows as a white histogram, so you can see some information to help confirm the power of the bears/bulls. The green/red shadow shows how the Bollinger's basis is changing, and when it is going up there will be a green shadow underneath the basis line (this can be inverted in the settings). There is also price line (yellow) showing the location of the price within the .
Use this indicator for trades at your own risk, I made this for fun and it is not a trade recommendation.
That being said, if you like my work please tip me!

My guess is because they're priced either really high or really low compared to stocks. I already added a fix for some cryptocurrency, but I haven't tested it in a while. I mostly use this for stocks.
Typically like TRX/BTC and/or SNT/BTC on Bittrex.
Bands reappear sometimes but after a long while...
My understanding of it is that Bessel's correction is needed when the calculation uses the mean of a sample like this rather than calculating the mean for the entire population. It reduces the bias and I think makes the calculation more accurate.
This is using the two-pass algorithm for stdev, with Bessel's correction. It is mathematically equivalent to Pine's version, but doesn't suffer from the same precision issue. If you want to see more about that, check my comments here:
