This indicator allows you to draw Bollinger bands using higher timeframes.
Note: The timer of your Bollinger Bands must be a multiple of the current chart of the chart. For example: If your chart is 4 h and you set the sync value to 3, the Bollinger Bands will be drawn with a 12H time frame. 3 * 4H = 12 If the sync is equal to 1, normal Bollinger bands are drawn and will be no different from the normal Bollinger band.
Using this indicator may be appropriate for fractal perspectives.
