Bollinger Band parameters

[leo <leo@xxxxxxxxxxx>]

Hi,

I looking for the standard Bollinger Bands parameters in a case of a weekly,
and a monthly chart.

For a daily chart the parameters are 20 day Average and 2 as standard
deviation.

Could somebody indicate me these parameters for a weekly and monthly chart ?

I thank you very much.

Best Regards.

Robert Vialet.
