SmaIndicator<T, D> class
Renders simple moving average (SMA) indicator.
A simple moving average (SMA) is an arithmetic moving average calculated by adding recent closing prices and then dividing the total by the number of time periods in the calculation average.
It also has a valueField property. Based on this property, the indicator will be rendered.

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.
