Hi
Here is an indicator that places two Bollinger Bands on the chart, as in Mark Whistler's book 'Volatility Illuminated'.
Helps to show short term volatility against longer term volatility.
Indicator can show-hide deviations and show-hide mid-line.
Indicator appears in group Bollinger in Marketscope.
Longer term band has multi deviations plotted.
