it is good. but it has a problem. when i turn off bollinger band, then 3 colors are changed. like the upper band color changes into the central SMA color, and the central SMA color changes into the lower band color.

Great Indicator. Thank you to the developer! It would be great if one converted this indicator to a Multi-Timeframe setup, whereby you can display higher timeframe Bollinger Bands on lower timeframes. Perhaps also having an available scroll Next and Previous timeframe button on the screen. Furthermore, have additional settings to convert the Bollinger Bands with different moving average methods, i.e. Simple, Linear, Exponential, Smoothed, etc.

For now...the indicator works and doesn't seem to have an bugs/glitches. Thanks again!
