CS0118 Indicator is a type - used as a variable - PriceTypeSupported

[giogio1]

This thread is mainly to inform people of how I resolved the error code CS0118 as I couldn't find the solution anywhere. Yet I still have questions on why do I need the line
PriceTypeSupported = true;
to resolve the error.

The offending line is in the indicator that includes MyIndicator:
MyIndicator manyEma = MyIndicator();

and in MyIndcator I basically have:
protected override void Initialize() {
Add(new Plot(Color.Green, "EMA"));
Plots[0].Pen.Width = 2;
Plots[0].Pen.DashStyle = DashStyle.Dash;
PriceTypeSupported = true;
}
[Browsable(false)]
[XmlIgnore()]
public DataSeries EMAflat { get { return Values[0]; }

Obviously the NinjaTrader generated code for the cache needs to be re-generate for the error to disappear.
