Threading issue

[ETFVoyageur]

I get an exception.

An exception of type 'System.InvalidOperationException' occurred in WindowsBase.dll but was not handled in user code

Additional information: The calling thread cannot access this object because a different thread owns it.

The exception comes from the following line of code. darkBullColor and darkBearColor are both of type System.Windows.Media.SolidColorBrush.

if (isUpTrend) PlotBrushes[rIndicatorPlot.index][0] = darkBullColor; else PlotBrushes[0][0] = darkBearColor;

What am I doing wrong?

--EV

P.S. I think it is irrelevant, but rIndicatorPlot.index = 0, and PlotBrushes has 2 entries.

Freeze() the brush after you create it.

Freeze() the brush after you create it.

Thank you. That seems to have solved the problem.
