AnyStock includes built-in math functions for technical indicators such as Bollinger Bands, which can be rendered as a range spline area series. A data table computer calculates indicator values on the fly, keeping chart code clean and data-driven.
This sample loads CSCO daily prices from CSV, computes 30-period Bollinger Bands with a 5-deviation multiplier using preset BBands math functions, and draws the upper and lower bands as a shaded range spline area. An OHLC series overlays the same plot so price action is visible against the volatility envelope.
Follow the step-by-step OHLC Chart Tutorial to learn how stock charts are built. See the AnyStock documentation for all configuration options.
