Finally, after few years trading with BollingerBand... Now I found this simple and usefull indicator to calculate Upper-Lower BB Range.....
Works great in major pair but still have bug when attach to JPY (EURJPY & USDJPY) in 4 digit broker,,,,, the width value is wrong.
I hope there will be v2.0 , to correct this issue.

Bollinger Bandwidth 1.0 for MT5:
The indicator measures the distance between the Bollinger Bands and providing it as a singular indicator, using the MetaTrader 5 techniques to simplify Bollinger calculations.
This new version designed with MetaTrader 5 takes the calculations of iBands and calls them to perform the calculations needed to get the difference between upper and lower bandwidths.
This version also comes with an attempt to provide a digits offset so that you can drop it on a 2 digit, 3 digit, 4, digit, or 5 digit and the resulting value should be correct.
