  • Welcome to the Investors Trading Academy talking glossary of financial terms and events.

  • Our term of the day isBollinger BandsBollinger Bands are volatility bands placed

  • above and below a moving average. Volatility is based on the standard deviation, which

  • changes as volatility increases and decreases. The bands automatically widen when volatility

  • increases and narrow when volatility decreases. This dynamic nature of Bollinger Bands also

  • means they can be used on different securities with the standard settings. For signals, Bollinger

  • Bands can be used to identify M-Tops and W-Bottoms or to determine the strength of the trend.

  • Standard deviations are a statistical unit of measure describing the dispersal pattern

  • of a data set. By definition, one standard deviation includes

  • about 68% of all data points from the average in what is referred to as a normal distribution

  • pattern, while two standard deviations include about 95% of all data points.

  • When working with Bollinger Bands, it is not necessary for you to calculate standard deviations

  • yourself. You need only understand the theory of how standard deviation sets the range for

  • a dispersal of rates when compared to the moving average, and how this information is

  • used to determine buy and sell channels in the chart.

  • The area between the moving average line and each band produces a range, or channel.

  • The area above the moving average is referred to as the buy channel as prices displayed

  • in this region remain higher than the moving average and suggest upward momentum. Conversely,

  • prices falling below the moving average are in the sell channel as the spot rate is declining

  • more rapidly than the moving average which suggests that the exchange rate has downward

  • momentum.
