This indicator calculated the StDev of a spezified period and calculates the upper and lower channel bonds.
It works nearly the same as the original bollinger band, but with following features:
Gaussian Filtration for centerline;
Gaussian Filtration for stDev;
StDev and centerline periods can be different. (You can add a 200bar average stDev to a 10 bar filterline);
2 different settings for 2 different bands.
