Referencing an Indicator that has an enum input

[Lost Trader]

I created an indicator that has one input variable, which is an enum as I wanted the user to select from a list. It works great. I also exposed certain values, for example:

        [Browsable(false)]    
        [XmlIgnore()]        
        public DataSeries HIST
        {
            get { Update(); return Values[2]; }
        }

Now I am writing another indicator in which I wish to use the first indicator. Yet when I wrote

DataSeries HistValues = IndName(eValue).HIST;

I get an error = The name 'eValue' does not exist in the current context.

DataSeries HistValues = Indicator(eName.eValue).HIST;

resulted in the error = An object refernce is required for the nonstatic field, method, or property 'NinjatraderIndicator.Indicator.IndName[eName]'

The enum is public in the original indicator file but outside the namespace NinjaTrader.Indicator as I thought that would make it available to all.

How do I use my indicator?

[Lost Trader]

OK, I added new

DataSeries HistValues = new Indicator(eName.eValue).HIST;

and now the error = No overload for method 'IndName' takes 1 arguments.

There is only 1 input variable under parameters -- none of the others are required for code usage (they affect display appearance only).
What does it expect and how to I fix it?

Lost Trader,

You can't create DataSeries like that. Please see this documentation on how to use DataSeries objects: http://www.ninjatrader-support.com/H...taSeriesObject

[Lost Trader]

You are missing the point, Josh. The same error occurs when trying to access the int exposed variable:

private int testJosh = new ERG(ERGType.Trading).PrimeState;

error = No overload for method 'ERG' takes 1 arguments.

If ERG is an indicator, you have to fill in a value for all public properties (I guess). In your case, there seem to exist more than just one.

Doesn't make sense, Ralph. I've checked the "do not change" section of NT code and all the routines have this expression

public ERG ERG(ERGType type)

No other input should be required.

Lost Trader,

You are using techniques that we do not support. You are welcome to try, but we cannot assist you with unsupported techniques. If you want to access a value, use [] indexing to get the value.

[Lost Trader]

Josh, exposing variables IS supported. In fact I believe it was YOU who told me to access an exposed variable, write the expression like this

[B]double indVal = IndicatorName().exposedVariable;[/B]

Fine. But it doesn't WORK. Are you now going to claim NT doesn't support exposed variables if the indicator requires an input?

[Ralph]

Doesn't make sense, Ralph. I've checked the "do not change" section of NT code and all the routines have this expression

public ERG ERG(ERGType type)

No other input should be required.

I agree with you.

If the compiler claims an illegal signature, there must be a reason? I am still confused about the new-statement in your example. Maybe because of that the compiler considers ERG(ERGType type) to be the class's constructor, wich doesn't exist with a single parameter?

[Lost Trader]

Well, Ralph, if I remove the new and

private int testJosh = ERG(ERGType.Trading).PrimeState;

it is back to the error = An object reference is required for the nonstatic field, method, or property 'NinjatraderIndicator.Indicator.ERG[ERGType]'

I would prefer this version to work, for sure.

[Ralph]

Yes, funny error message. Could you try the more expicit version, even if it should work as you describe?

private int testJosh = base.ERG(ERGType.Trading).PrimeState;

Does your custom-indicator inherit from Indicator()?

Regards
Ralph

[Lost Trader]

Well it is different. Error = Keyword 'base' not available in the current context

Don't all indicators created in NT inherit ?

[Ralph]

Don't all indicators created in NT inherit ?

Not automatically, you have to declare it:

public class ERG : Indicator
{
}

Regards
Ralph

[Lost Trader]

Actually this is automatic when created with NT.... (and yes it is there)

public class ERG : Indicator

I would have never known to add it, but I checked and it is there.
I'd love more suggestions - I need a solution.

[Ralph]

My impression about the error message is that the compiler recognises method ERG() in baseclass Indicator() correctly, but in your code it suspects a static application (not bound to a class instance).

Where did you place ERG(...) in your code? Is it OnBarUpdate?
Do you use own namespaces?
Would this code compile: private ERG testJosh = ERG(ERGType.Trading);
