The example shows how to use custom code and build in financial functions. In this case the chart displays different Range Indicators.
Bollinger Bands are drawn at a given number of standard deviations from a moving average of a price. Since standard deviation is a measure of volatility, the bands are self-adjusting: widening during volatile markets and contracting during calmer periods. Bollinger Bands were created by John Bollinger.
