Description
The MovingAverageLineStyle() function can be used to control the appearance of the moving average lines. The 4th argument shape controls the shape of the curve — smooth, polygonal or step-like; details can be found in Line Shapes. The stroke and color of the average lines can be varied using the arguments stroke, color and colorVariant. Unless otherwise defined, average lines are black, one-pixel wide lines.

Currently, three methods are available to calculate moving averages. Details can be found at the MovingAverageOptions() function. By calling the MovingAverage() function repeatedly, several moving averages can be represented at the same time for both different data series and for a different number of intervals.
