Two Bollinger Bands indicators, accomplices, linked together one into the other. One drawn, the other not drawn but coloring the first one.
The role of indicator No. 2, the one with the smallest standard deviation, is, in fact, to define a neutral zone. If one leaves it, a buy or a sell position is suggested. By playing on the period and the standard deviation of n°2, we increase or shrink the neutral zone, we lengthen
or shrink the colored zones of the first.

hello, thank you for sharing, I’m not top strong in the programation part, there is a way to provide us with an automatic trading strategy?
Hi, With this indicator I just wanted to show the interest that can exist to synthesize the information of 2 indicators in a single image. In my example, indicator 2 can, of course, be replaced with whatever you want. Finally, to answer your question more precisely, I have not written a program for an automatic trading strategy. Sorry !
how to adapt nbStdSig values ?
