A two-line band is plotted on the chart, inside which the price chart is located. The indicator plotting method exactly repeats the plotting of the Bollinger Bands, except for the calculation of the distance to which the extreme lines are remote from the average line. While the Bollinger Bands are calculated with the use of the standard deviation, in envelopes this distance is set manually in settings.
