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.

Please let me know if you have any other questions.

Thank you. This is exactly the information needed.

[Browsable(false)]

public string MyBrushSerialize

{

get { return Serialize.BrushToString(MyBrush); }

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

}

Hey Gaby

If I created this "MyBrushSerialize", I need to manually call it for it to be effective correct? Otherwise It has no use? Can you provide an example for how to use this specific property?

PS: NVM I understand, so basically the default behavior of NT8 is to serialize all the public properties and deserialized all of them when reload, hence when NT8 try to serialize MyBrushSerialize, it calls its get function, and when it deserialized it calls its set function.
