1st off, thanks to ThinkDecoded for converting my TOS code over to NinjaTrader 8. It works properly when I hard code the colors for up/down conditions.
Example:
// Cambiar colores según la tendencia
PlotBrushes[0][0] = emaSeries[0] > emaSeries[1] ? System.Windows.Media.Brushes.White : System.Windows.Media.Brushes.Black;
PlotBrushes[1][0] = smoothingLine1[0] > smoothingLine1[1] ? System.Windows.Media.Brushes.LightGreen : System.Windows.Media.Brushes.Red;
PlotBrushes[2][0] = smoothingLine2[0] > smoothingLine2[1] ? System.Windows.Media.Brushes.LightGreen : System.Windows.Media.Brushes.Red;
PlotBrushes[3][0] = smoothingLine3[0] > smoothingLine3[1] ? System.Windows.Media.Brushes.Blue : System.Windows.Media.Brushes.Purple;
However the color selection inside the setting dialog for each EMA does not work. I tried to message ThinkDecoded about it, but haven't received an answer.
Here is the code. Any help would be greatly appreciated, Thanks!
Code:
#region Using declarations

using NinjaTrader.Gui.Tools;

using System.Windows.Media; // Necesario para Brushes

{
if (State == State.SetDefaults)
{

AddPlot(System.Windows.Media.Brushes.LawnGreen, "EMA Line");

AddPlot(System.Windows.Media.Brushes.Blue, "Smoothing Line 2");
AddPlot(System.Windows.Media.Brushes.Black, "Smoothing Line 3");
}
else if (State == State.DataLoaded)
{
emaSeries = EMA(Close, Length);
smoothingLine1 = EMA(emaSeries, SmoothingLength1);
smoothingLine2 = EMA(emaSeries, SmoothingLength2);
smoothingLine3 = EMA(emaSeries, SmoothingLength3);
}
}
protected override void OnBarUpdate()
{
if (CurrentBar < Math.Max(Length, Math.Max(SmoothingLength1, Math.Max(SmoothingLength2, SmoothingLength3))))
return;
// Asignar valores a los plots
Values[0][0] = emaSeries[0];
Values[1][0] = smoothingLine1[0];
Values[2][0] = smoothingLine2[0];
Values[3][0] = smoothingLine3[0];
// Cambiar colores según la tendencia
PlotBrushes[0][0] = emaSeries[0] > emaSeries[1] ? System.Windows.Media.Brushes.White : System.Windows.Media.Brushes.Black;
PlotBrushes[1][0] = smoothingLine1[0] > smoothingLine1[1] ? System.Windows.Media.Brushes.LightGreen : System.Windows.Media.Brushes.Red;

}
}
