I am trying out MC.Net from AMP, but it turned out that I have to be paid user to post on MC.Net's official discussion forum. So I hope that I can get help in nexusfi.com (formerly BMT) instead.

I programmed my first really simple indicator CurrectionBar modeling off C_Hammer_HangingMan.Function and .Indicator

But when I ran it, I got this error message. I checked 10+ times on what is different between my indicator and the C_Hammer_HangingMan but got no luck. Could you please help to check it out what I did wrong?

That's normally not a very hard error message to solve. Can you post your code in a .txt file? I'm not a big fan of importing .pln files with unseen code.

Thanks for the reply.

I found the reason now. It is because in C_Hammer_HangingMan.Function.CS, for some unknown and strange reason, it declares the two output objects, but do not initialize them.



and it depends on the C_Hammer_HangingMan.Indicator.CS to pass in an empty object.

Do you happen to know what is the good on handling this way? to me it is much simpler to declare this way:

 

Code

private VariableSeries<double> m_ohammer; public ISeries<double> ohammer{ get { return m_ohammer; } }

and below is my whole function of correction bar:

 

Code

using System; namespace PowerLanguage.Function { public class C_CorrectionBar_Up_Down : FunctionSeries<Double> { //Declare variables private VariableSeries<double> m_oCB_Up; public ISeries<double> CB_Up{ get { return m_oCB_Up; } } private VariableSeries<double> m_oCB_Down; public ISeries<double> CB_Down{ get { return m_oCB_Down; } } //Declare structurer public C_CorrectionBar_Up_Down(CStudyControl ctx) : base(ctx) {} public C_CorrectionBar_Up_Down(CStudyControl ctx, int data_stream) : base(ctx, data_stream) {} //create function, which initiatializes classes needed for the class protected override void Create(){ m_oCB_Up = new VariableSeries<Double>(this); m_oCB_Down = new VariableSeries<Double>(this); } protected override void StartCalc(){ } protected override double CalcBar(){ m_oCB_Up.Value = 0; m_oCB_Down.Value = 0; if (Bars.CurrentBar > 2){ if (Bars.High[1]>Bars.High[0]) { m_oCB_Up.Value = 1; } else{ if (Bars.Low[1]<Bars.Low[0]) { m_oCB_Down.Value = 1; } } } return 1; } } }

I always use an automatic property in Visual Studio since that's easier to code (with the `prop` code snippet) and is the same as MultiCharts uses in their programming manual.

I don't know if this is the 'good' or 'best' way, I don't think it matters that much as long as both compile and are recognised by MultiCharts .NET as an input.

Speaking of Visual Studio, I do like VS better, but I found that the solution only includes indicators and signals; it does not include functions classes. Such as ADX, ADX.Function.cs is not in the solution.

Do you have "hacks" around it?

It would be nice if there were 'hacks' around, but I don't know of any. What I do know is that functions are built-in the PowerLanguage .NET Editor (see MultiCharts: Trading Software for Automated Trading and Backtesting ? View topic - MultiCharts .NET FAQ), so I don't expect them to be available in the VS anytime.
