Bollinger Bands Clouds provides Bollinger Bands of different timeframes in a chart. It actually shows BB from a new angles.
This indicator can show three BB from different timeframes simultaneously.
The idea is to be able to combine different levels of BB from other timeframes in one chart Each cloud is a Bollinger band whose time frame is a multiple of the current chart time frame. If this multiplier is set to 1, its Bollinger bands will be drawn for the current time frame and will be no different from normal Bollinger bands. This indicator can be suitable for fractal perspective. Multipliers can be changed from within the indicator settings: settings -> mult1, mult2 and mult3
For a dark theme, enable the Dark Theme option from the indicator settings.
