 When I include Bollinger Bands in the chart template with the default setting of 20,2, they obviously are displayed incorrectly. They are much too narrow so that they are very tight relative to the 20ma, thus not providing that "rubber band" look to price on the chart. When I increase the width to 20, they look much more like the 20,2 setting in (URL removed by Moderator). Am I missing something? What is the correct way to set BB's with the 20,2 setting to get the accurate indicator on the chart?

 I cannot say anything about accuracy.

I can say the WIDTH setting in TeleChart is the Standard Deviation X 10. If you want two standard deviations, set the WIDTH to 20.

 Thanks for your reply.

When you say "standard deviation X 10" do you mean instead standard deviation DIVIDED by 10? That would make sense given that you have to multiply by 20 to get 2 std. deviations. So I imagine that's the case with all indicators in that the width is SD/10?

 No. The Width Setting is:

StD X 10

So a StD of 2 is a width of 20

(2)X(10)=20

2/10 is 0.20
