AtrIndicator<T, D> class

This class holds the properties of the average true range indicator.

ATR indicator is a technical analysis volatility indicator. This indicator does not indicate the price trend, simply the degree of price volatility. The average true range is an N-day smoothed moving average (SMA) of the true range values.

Provides options for series visible, axis name, series name, animation duration, legend visibility, signal line width, and color to customize the appearance of indicator.

Properties

animationDelay → double
Delay duration of the technical indicator's animation. It takes a millisecond value as input. By default, the technical indicator will get animated for the specified duration. If animationDelay is specified, then the technical indicator will begin to animate after the specified duration.
