AccelerationBands: Indicator Documentation
Syntax
DataSeries AccelerationBands( Bars bars );Parameter Description
Description
The Acceleration Bands indicator created by Price Headley serve as a trading envelope that factor in a stock's typical volatility over standard settings of 20 or 80 bars. These bands tend to be a bit wider than Bollinger bands which makes it even more significant when a stock breaks out above them. The author uses the 20-day bands as a general rule. See his book "
Big Trends in Trading" for the formula.
Example
This example illustrates how to construct and plot the Acceleration Bands.
