Default User Definable Color Inputs

Applies to NinjaTrader 7

User definable inputs do not need to be limited to numeric values. You can have colors as an input as well. To do this you will need to make a public property for a Color object instead of an int or double.

In the "Properties" region of your code, there is only a slight change in the code snippet you would normally use to create user definable inputs. You need an extra line above the Description field.
Code:
[XmlIgnore()]
[Description("Color for painted region")]
[GridCategory("Parameters")]
The second difference is in the next line of code:
Code:
public Color PaintColor
{
     get { return paintColor; }
     set { paintColor = value; }
}
This creates a color input for use in the dialog window when we try to add the NinjaScript to a chart.

Some additional extra code that is required for creating a color input is to serialize the color. Serialization is necessary for NinjaTrader to use the color input throughout the program. Please note that serialization is a general concept not exclusive to color inputs. There may be other struct/classes (e.g. TimeSpan) that you could use in your code that would also need to have their "value" properties serialized.
Code:
[Browsable(false)]
public string PaintColorSerialize
{
     get { return NinjaTrader.Gui.Design.SerializableColor.ToString(paintColor); }
     set { paintColor = NinjaTrader.Gui.Design.SerializableColor.FromString(value); }
}
Attached is a NinjaScript indicator sample that uses two user definable color inputs to determine the color of a drawn rectangle.

User definable inputs do not need to be limited to numeric values. You can have brushes as an input as well. To do this you will need to make a public property for a Brush object instead of an int or double.

In the "Properties" region of your code, there is only a slight change in the code snippet you would normally use to create user definable inputs.
Code:
[XmlIgnore()]
[Display(Name = "BorderBrush", GroupName = "NinjaScriptParameters", Order = 0)]
The second difference is in the next line of code:
Code:
public Brush BorderBrush
{ get; set; }
This creates a brush input for use in the dialog window when we try to add the NinjaScript to a chart.

Some additional extra code that is required for creating a color input is to serialize the brush. Serialization is necessary for NinjaTrader to use the brush input throughout the program. Please note that serialization is a general concept not exclusive to brush inputs. There may be other struct/classes (e.g. TimeSpan) that you could use in your code that would also need to have their "value" properties serialized.
Code:
[Browsable(false)]
public string BorderBrushSerialize
{
	get { return Serialize.BrushToString(BorderBrush); }
   	set { BorderBrush = Serialize.StringToBrush(value); }
}

Futures, foreign currency and options trading contains substantial risk and is not for every investor. An investor could potentially lose all or more than the initial investment. Risk capital is money that can be lost without jeopardizing ones financial security or lifestyle.

CFTC Rules 4.41 - Hypothetical or Simulated performance results have certain limitations, unlike an actual performance record, simulated results do not represent actual trading. Also, since the trades have not been executed, the results may have under-or-over compensated for the impact, if any, of certain market factors, such as lack of liquidity. Simulated trading programs in general are also subject to the fact that they are designed with the benefit of hindsight.
