One of the indicators used by technical analysts is Bollinger Bands In this Observation, we look at Bollinger Bands applied to weekly 10 year U.S. Treasury Yields.

The concept of Bollinger Bands is simple, applied statistics. In the top panel of the chart below, Bollinger Bands are plotted two standard deviations above and below a 20-week simple moving average of the close. The weekly close is used to calculate both the standard deviation and the 20-week moving average. Statistics tells us that approximately 95% of all observations will fall within two standard deviations of the mean (moving average).

The bottom panel uses a formula to depict %B, the close for any period within the Bollinger Bands. At 100 you are at the upper band, at 50 you are at the middle band and at 0 you are at the lower band. %B can exceed 100 or fall below 0, which occurs when the close is outside of the bands. At 110 you are 10% of the Bandwidth above the upper band and at -10 you are 10% of the Bandwidth below the lower band.
