Please help me to plot a chart (using Rules or Drag and Drop) that shows the following Indicators.

90-Day Moving Average
1-Standard Deviation Above and Below
2-Standard Deviations Above and Below

I am able to create a 90-day Moving Average line by dragging and dropping the SMA Indicator from the W-L Standard Indicators portfolio, and setting its period to 90. I also found a "Standard Deviation" indicator in the same Standard Indicators portfolio, but cannot figure how to apply this indicator to produce the above chart (when I drag and drop this indicator, a second chart window appears that shows, apparently, the values of a "standard deviation"). Can you please help me create the above chart?

Look for BBandUpper and BBandLower. These are your envelopes plotted at a standard deviation level above and below a simple moving average of the price.
