Is it possible to set PlotBrushes in hosted indicator?

[fx.practic]

Hello.
I made a strategy. And I want to set PlotBrushes propertie of hosted indicator:

MACD Macd = MACD( 10, 20, 30);

AddChartIndicator( Macd );


OnBarUpdate{}
{
   Macd.PlotBrushes[0][0] = Brushes.Green;

   TriggerCustomEvent( (o) => {Macd.PlotBrushes[0][0] = Brushes.Green;}, null );

   Macd.TriggerCustomEvent( (o) => {Macd.PlotBrushes[0][0] = Brushes.Green;}, null );
} 

Any of these ways not work.
Is it possible?

Hello,

I show that this syntax would work, is there a need for TriggerCustomEvent in this case?

Also, have you correctly stored the instance of the macd as a variable?

private MACD Macd;
protected override void OnStateChange()
{
	if (State == State.DataLoaded)
    {
		Macd = MACD( 10, 20, 30); 
        AddChartIndicator( Macd ); 
	
    }
}

protected override void OnBarUpdate()
{
	Macd.PlotBrushes[0][0] = Brushes.Pink;
}

I look forward to being of further assistance.

I am sorry, my fault.
Just, return triggered before color setting.

Thank You, and sorry again.
