Custom indicators let you define your own calculation logic using AnyChart's data table computer API and render the result as any stock series type. This extends the built-in indicator library with proprietary formulas, composite signals, or experimental algorithms tailored to specific trading strategies.
This sample plots CSCO daily closing prices as a line series and overlays a custom indicator that adds a random increment to each data point, demonstrating the createComputer/addOutputField/setCalculationFunction workflow. The computed series is rendered as a semi-transparent orange (#ffa000) line on the same plot. The chart features dual Y-axes, a synchronized line scroller, a range picker, and a range selector.
See the Technical Indicators documentation for all configuration options.
