• TMA (TriangularMovingAverage).
• TEMA (TripleExponentialMovingAverageTema).

To show the indicator for a series, add the required MovingAverage class descendant to the series’ collection of indicators, accessible via the XYDiagram2DSeriesViewBase.Indicators property.

To select whether to show a Moving Average, Envelope or both, use the MovingAverage.Kind property.
