User Definable Color Inputs

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.

The second difference is in the next line of code:
public Brush BorderBrush |
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 (for a TimeSpan example, please cross reference this page) that you could use in your code that would also need to have their "value" properties serialized.

Attached is a NinjaScript indicator sample that uses two user definable brush inputs to determine the color of a drawn rectangle.
