This study tracks where the 5MA is relative to the Bollinger Bands
Bollinger Bands are segmented in four parts, +/- 2 stdDev and +/- 1 stdDev
+/- 1 : first StdDev Band
+/- 4 : Second StdDev Band
+/- 9 : Overbought / Oversold (Beyond 2nd SD Band)
This study is used to reduce the clutter on the screen. Instead of displaying the whole band, it displays a map that shows on which band the price is located. And provides at a glance the strength of the trend.
