Add Indicator with Expandable Property

[Zeos6]

Hi,

I am trying to add an indicator to my strategy. The indicator has an expandable property. How does one specify the input values for the expandable property inside the strategy? Any advice would be greatly appreciated. Thank you.

Hello Zeos6,
Thanks for your post.

Alot of the time you just need to include that input inside your call to the indicator. For example, we'll call my custom indicator "AAA" , if I have a boolean drop down selector inside my indicator AAA's parameters, I would set that by doing something similar to the following in my strategies code.

else if (State == State.DataLoaded)
{
	AddChartIndicator(AAA(true));
}

If you have multiple selectable parameters you will need to make sure you are setting the correct one. For that you can use the built in intelliPrompt inside the NinjaScript editor. I am including a link to that help guide page below. intelliPrompt will let you know what order your inputs are in and the type of input.

Please let me know if you have any questions.

Thanks for the reply Josh but this is is not answering my question. I know how to set the values of simple indicator properties.

The issue is how to set values for an expandable property created via a class. The property will generally not have a [NinjaScriptProperty] attribute. If the attribute is added, then I get the error:

The type or namespace name 'MyPropertyClass' could not be found (are you missing a using directive or an assembly reference?)

How exactly does the [NinjaScriptProperty] attribute work?

Hello Zeos6,
Thanks for letting me know.

I believe the following forum post is what you are looking for. It discusses how to create user defined input parameters. The second link goes over parameter sequencing.

If this is not what you are looking for please provide a sample of the code.

Let me know if you have any questions.

Thanks Josh.

However, this does not even touch the core of my question. The question deals with Expandable properties. Specifically, with how to set the expandable property values from a strategy.
