    Hello glivv,

    Thank you for your patience.

    The solution as of now is to use a solid brush color.

    I have attached a script which will hold its color.

    Code:
    [XmlIgnore()]
    		[Display(Name = "FillBrush", GroupName = "NinjaScriptParameters", Order = 1)]
    		public SolidColorBrush FillBrush
    		{ get; set; }		
    		
    		[Browsable(false)]
    		public string FillBrushSerialize
    		{
    			get { return Serialize.BrushToString(FillBrush); }
       			set { FillBrush = (SolidColorBrush)Serialize.StringToBrush(value); }
    		}
    Please let us know if you need further assistance.

    Hello Allan

    even if I use code per your suggestions, i.e.:

    Code:
    namespace NinjaTrader.NinjaScript.Strategies
    {
    	public class TstBrush : Strategy
    	{
    		private	Brush boxColor = Brushes.Green;
    		
    		[XmlIgnore()]
    		[NinjaScriptProperty]
    		[Display(Description = "BoxColor", GroupName = "Parameters", Order = 4)]
    		public Brush BoxColor
    		{
    			get{return boxColor;}
    			set{boxColor = value;}
    		}
    		
    		[Browsable(false)]
    		public string BoxColorBelowSerialize
    		{
    			get{return Serialize.BrushToString(boxColor);}
    			set{boxColor = Serialize.StringToBrush(value);}
    		}
    		
    		protected override void OnStateChange()
    		{
    		}
    	}
    }
    I still see that BoxColor input is reverted back to default value after run in Strategy Analyzer.

    That is, open Strategy Analyzer, choose TstBrush strategy, change BoxColor from Green to any other value, White for example, select symbol/timeframe/period and press Run. When backtest finishes, BoxColor input is reverted to Green. It doesn't stay at White.

    Hello glivv,

    If you add the print statement in the screen shot within SetDefaults and open an output window, then pull up a strategy analyzer and queue up the strategy, run the analyzer, you will see how often this block is ran. Setting the value within SetDefaults is going to cause the brush to be set back to this value.

    You should set the value of the brush outside of State.SetDefaults.

    Please let us know if you need further assistance.

    So, unlike any other (like integer or string) properties, Brush property cannot be set in "State == State.SetDefaults" branch in OnStateChange()?

    Hello glivv,

    Thank you for your note.

    I revised your script and provided the correct way to go about taking a brush input as well as serializing it.

    Code:
    private	Brush boxColor = Brushes.Green;
    		
    		[XmlIgnore()]
    		[NinjaScriptProperty]
    		[Display(Description = "BoxColor", GroupName = "Parameters", Order = 4)]
    		public Brush BoxColor
    		{
    			get{return boxColor;}
    			set{boxColor = value;}
    		}
    		
    		[Browsable(false)]
    		public string BoxColorBelowSerialize
    		{
    			get{return Serialize.BrushToString(boxColor);}
    			set{boxColor = Serialize.StringToBrush(value);}
    		}
    Please let us know if you need further assistance.

    Brush field in Strategy Analyzer

    Hi,

    I'm having problem with Brush field resetting to default value after run in Strategy Analyzer.

    See attached sample strategy.

    I open Strategy Analyzer window, change integer and Brush values (before_pressing_run screenshot) and press Run. After completion (after_pressing_run screenshot) integer value stays but Brush value reverts to default one.

    What am I doing wrong?
