error message CS1501 problem

[joemiller]

I created an indicator with no input parameters and it compiled with no errors.
I changed nothing in the indicator code meaning I did not replace the “Plot0.Set(Close[0]);” statement in the “OnBarUpdate()” section [reproduced below in larger font].

protected override void OnBarUpdate()
{
// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.
Plot0.Set(Close[0]);
}

I added an “Add(joeHACindicator());” statement to my strategy
expecting a line to appear on a strategy analyzer chart passing
thru the close of every bar.

However , the strategy failed to compile with the error CS1501 “no overload for method ‘joeHACindicator’ takes ‘0’ arguments.”

I have absolutely no idea what that means or where to start trying to resolve the problem so will greatly appreciate any help.

Hello,

We would need to see the joeHACindicator in order to know how to reference it correctly.

indicator code is attached, i think? thanks Matthew

code was > 10,000 so had to attach it.
after several attempts to save a Word doc in acceptable format I think it finally is happy with a pdf file which is what I think is attached.

for future reference what procedure should I use to attach a file?

[NinjaTrader_Matthew]

In the future, you can always just upload the actual cs file contained in Documents\NinjaTrader 7\bin\custom\Indicator\<your indicator name>.cs

Your indicator is expecting input from the following parameter:

[Description("")] 
[GridCategory("Parameters")] 
publicint MyInput0 
{ 
get { return myInput0; } 
set { myInput0 = Math.Max(1, value); } 
}

You will either need to remove this area in the code, or you can simply pass a dummy value to the indicator in the strategy:

Add(joeHACindicator(1));

creating a new indicator when the indicator has no input parms:

regarding use of the wizard to create a new indicator when the indicator has no input parms:

I tried deleting the automatic specification of MyInput0 and Plot0 resulting in a skeleton code for the indicator [ie] appeared to contain no prebuilt code which means the wizard did nothing of use to me.

so is the following the best way to create an indicator which has no input parms using the wizard?
1. change nothing, just use the wizard defaults for MyInput0 and Plot0.
2. then do as suggested below [ie]
Your indicator is expecting input from the following parameter:
Code:
[Description("")] [GridCategory("Parameters")] publicint MyInput0 { get { return myInput0; } set { myInput0 = Math.Max(1, value); } }
You will either need to remove this area in the code, or you can simply pass a dummy value to the indicator in the strategy:

new indicator which uses in its definition an existing indicator

I am trying to create a new indicator [joeHAOindicator] which uses in its definition an existing indicator [joeHACindicator3] created previously by me.
I am getting the old familiar cs error messages [ie] cs1501,02,03,19 & 21. As before I cannot figure out how to fix the problem. I have read the error messages and unsuccessfully experimented with various attempted fixes.

Code for joeHAOindicator is attached. Hate to dump it on you but I am doing it anyhow.
Your help will be much appreciated.

Please post the region for joeHACindicator3.

this is what joeHAOindicator looks like:

// This namespace holds all strategies and is required. Do not change it.
namespace NinjaTrader.Strategy
{
    public partial class Strategy : StrategyBase
    {
        /// <summary>
        /// trash    temp for test

        [Gui.Design.WizardCondition("Indicator")]
        public Indicator.joeHAOindicator joeHAOindicator(int myInput0)
        {
            return _indicator.joeHAOindicator(Input, myInput0);
        }

        /// <summary>
        /// trash    temp for test

        public Indicator.joeHAOindicator joeHAOindicator(Data.IDataSeries input, int myInput0)
        {
            if (InInitialize && input == null)
                throw new ArgumentException("You only can access an indicator with the default input/bar series from within the 'Initialize()' method");

            return _indicator.joeHAOindicator(input, myInput0);
        }
    }
}

Did you try as NT_Mathew suggested earlier?

You will either need to remove this area in the code, or you can simply pass a dummy value to the indicator in the strategy:

Code:
[I]Add(joeHACindicator(1));
[/I]

Your constructors require a parameter.

        public joeHAOindicator joeHAOindicator(int myInput0)


        public joeHAOindicator joeHAOindicator(Data.IDataSeries input, int myInput0)

[joemiller]

yes, I did do as Mathew suggested which is why joeHACindicator finally compiled and worked successfully when plotted on a strategy analyzer graph.

should public joeHAOindicator joeHAOindicator(int myInput0) and
public joeHAOindicator joeHAOindicator(Data.IDataSeries input, int myInput0)
go in joeHAOindicator or joeHAC3indicator, or both?

HAOindicator fails to compile, with error code cs0542

joeHAOindicator fails to compile with error code cs0542. Clicking for info gives no further info.

I have not a clue what is meant by the error description "joeHAOindicator' member names cannot be the same as their enclosing type".

Any help will be greatly appreciated.

A program listing is attached.

I added two lines of code at lines 27 & 28.

Please remove lines 27 and 28.

I only quoted that code, because I was showing you the ninjatrader generated constructor for your other indicator, trying to show that it takes a number as a parameter, and what NT_Matthew suggested (put a number) would make it compile.

thanks Sledge.

one of my problems is I have no idea what a 'constructor' is.
I will work on that problem now.
