persistence of custom brush colors / settings

[mohawkTrader]

Hi, I'm trying to get custom brush colors (set from the indicator settings) to persist when the NinjaScript reloads. This appears to impact Templates as well.

For example, the default color is Blue, but I add an indicator and change the color to Red. When I save as a template, and then load the template elsewhere, the color reverts to blue.

Here some sample code that draws a simple line at certain times. Bolded parts are the likely important lines. Can someone help me here or point to some documentation which would lead me in the right direction? Thanks.

Hello mohawkTrader,


Thank you for your post.


In order to properly serialize the Brush, you will need to add code to convert the public "MyBrush" to a string type which can then be processed by the serialization routines, meaning it can be saved and then loaded from a template.

[Browsable(false)]

public string MyBrushSerialize

{

get { return Serialize.BrushToString(MyBrush); }

set { MyBrush = Serialize.StringToBrush(value); }

}

Please see the following Help Guide page.
