RsiIndicator<T, D> class
Renders relative strength index (RSI) indicator.
The relative strength index (RSI) is a momentum indicator that measures the magnitude of recent price changes to evaluate overbought or oversold conditions.
The RSI indicator has additional two lines other than the signal line. They indicate the overbought and oversold region.
The upperLineColor property is used to define the color for the line that indicates overbought region, and the lowerLineColor property is used to define the color for the line that indicates oversold region.

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.
