Changing Line color

[ATMtrader0001]

I have added an SMA to my chart and I would like to change the color of it based on the direction of the movement.

I have added it using:
TrendLine = SMA(33);
TrendLine.Plots[0].Brush = Brushes.Red;
AddChartIndicator(TrendLine);

When I set it as above it is always Red.

If I try to set is OnBarUpdate() as below it does not work.
TrendLine.Plots[0].Brush = Brushes.Green;

What is the Proper way to set the color during OnBarUpdate()?
I've seen this done, but all my testing and searching hasn't helped.

Thanks.

Hello ATMtrader0001,

Thanks for your post.

PlotBrushes could be used to determine the color of a plot when certain conditions become true.

See the attached example script demonstrating how to change the color of a plot in a strategy when certain conditions become true. In the example script, we add the SMA indicator on the chart using AddChartIndicator(). Then, when we have an up bar, we use PlotBrushes to change the plot color to blue. When we have a down bar, we use PlotBrushes to change the plot color to pink.

Also, see this help guide page for more information: https://ninjatrader.com/support/help...lotbrushes.htm
