Call an indicator inside another indicator

[stupiddove]

I called an indicator(test) inside another indicator (test2). I found that test's OnBarUpdate was not called. Only test2's OnBarUpdate was called. I expected both OnBarUpdate should be called. Did I make a mistake?
The scripts are attached here. Thank you.

Hello,

Thanks for your post.

A good reference would be to check the example in the help guide here: https://ninjatrader.com/support/help...alues_that.htm
While the example is mainly about exposing a bool series, it also shows how to expose a variable.

In test.cs, at the class level you could add: private int value = 10;

Below the OnBarUpdate{} section you could add:

#region properties

public int TestValue
{
get { Update(); return value; } // put the private int value into public Test Value.
}
#endregion

In test2.cs, just change myTest.value to myTest.TestValue.

Thank you for your help.

I slightly modified the scripts. I did not call the update() for the variable value, but I added a Series<int> object in test.cs, OnBarUpdate was called. Does the Series<T> object trigger OnBarUpdate ?

My scripts are attached here.

Hello,

Thanks for your reply.

Yes, the series would call the OnBarUpdate for the hosted script.

We've recently updated the help guide to clarify "Hosted indicators will need to be accessed by the hosting script to ensure OnBarUpdate functionality. This can be done by: 1) Calling Update on the hosted indicator within the host script, 2) Including a plot in the hosted indicator and accessing the plot in the host script, 3) Including a plot in the hosted indicator and adding the indicator to the chart with AddChartIndicator (strategies only)" Reference: https://ninjatrader.com/support/help...nbarupdate.htm (Accessing the series would do the same as a plot in terms of the hosted script).
