Calling value calculated by an indicator (NOT PLOTTED) in a strategy

[AndreaBhs]

Dear Support,

I'm trying to get value from my custom indicator into my strategy.
I can access to plot value without problem using another indicator (like SMA(), VOL(), ecc), but if I try to access to these variables like below i can't.

Variables check1, check2, check3 and trendS are public in my custom indicator, so i have not compiling problem.
but if I Print this values they are wrong., whie in my indicator are correct.

I think problem is that this 4 variables aren't Plot[] Values in my indicator, this doesn't plot any Values[], just do some calculations and render some line

How can I access to these variables?

thank you, best regards

Hello AndreaBhs,

Thanks for your post.

If I understand correctly the issue is not accessing the values but getting the correct values.

Please see the help guide here: https://ninjatrader.com/support/help...t8/?update.htm

In your strategy, in the OnBarUpdate() try: myRitracciamento.UpDate();

Dear PaulH, thanks for your reply.

Yes, I need to get the correct value in real time.

If try myRitracciamento.Update(); I haven't compile error, but I have this error:

Error on calling 'EventHandlerBarsUpdate' method: Object reference not set to an instance of an object.

What's the problem?

Hello AndreaBhs,

Thanks for your reply.

Please remove that line.

In your indicator, you will need to modify the public properties as shown in the help guide example in post #2.

Hello AndreaBhs,

I had meant to also provide this educational example: https://ninjatrader.com/support/help...alues_that.htm

Hello Paul H.,

in my indicator I have:

// Variables 

bool check1 = false;

OnBarUpdate()
{
   check1 = true;
}


#region Properties
public bool Check1
{
   // We need to call the Update() method to ensure our exposed variable is in up-to-date.
   get
   {
   Update();
   return check1;
   }
}
#endregion

in my strategy I deleted the line

myRitracciamento.Update()

and i have write

Print(myRitracciamento.Check1);

It compile without any error, but in the Print I have again the previous error:

Strategy 'TestRitracciamento': Error on calling 'EventHandlerBarsUpdate' method: Object reference not set to an instance of an object.

I don't know where is the problem

sorry and thank you for your help

Hello AndreaBhs,

Thanks for your reply.

I would need to see all of your scripts to best assist.

Can you post the cs files (easier to plug in and test with) for both your strategy and indicator ?
