Out Params for a Function

Can you do out params for a MultiCharts.Net function? I mean like ByRef parameters in EasyLanguage?

Other than the programming guide, is there other beginner tutorial on MultiCharts.Net?

Thank you very much!

Hello ivanyu,

That is possible to do that.

Our Wiki section provides detailed up-to-date information about current MultiCharts functionality.
As for the .Net programming guide - MultiCharts .Net is oriented to experienced programmers. In case you have any questions regarding C# coding we recommend referencing MSDN for information. Interfaces and classes available in MultiCharts .Net are described in MC .Net help file (PowerLanguage .Net Editor->Help tab-> PowerLanguage .Net Help). You can also find the code examples in the source code of the prebuilt MultiCharts studies (PowerLanguage .Net Editor->File tab->Open).

Thank you for the reply.

I am not an expert C# developer but an average one. I have to admit that the C# classes are somewhat more complicated than it needs to be, primarily because (I think) it needs to mimic Easy Language and attempts to provide a wrapper classes/interfaces on top of it, as opposed to a brand new clean set of classes. Quite a few things can be encapsulated to a larger extent, rather than passing the complexity over to the developer.

When I look at the other trading software C# API (not implying it is better), it is much simpler because it does not need to wrap and build on top of anything.

e.g. MC.NET does not seem to make use of operator overloading to make the syntax easier, but chose to use interface and templates extensively.

Back to my question on reference parameters on a function, do I need to do something like below?

public IVar<Double> operiodopen { get; set; }

Then openiodopen will be a pass by reference param?

Thanks again for your help!!!

Thank you for your feedback. We will do our best to make using classes in C# as easy and straight forward as possible.

public IVar<Double> operiodopen { get; set; }

That is correct. You can also have a look at the prebuilt DMI indicator that uses the DirMovement function.

This is a very good observation. I am an advanced C# programmer and I still find it hard to code MC.NET mainly because the interfaces are not described in reference to objects that are readily available in CalcBar. I think you are correct that trying to adhere to EasyLanguage history is what has made this so difficult. I posted elsewhere that with some more glue-documentation they could tie some of the interfaces to objects and it then is really not as hard.

MultiСharts team,

Carry on and release a better, simpler C# API please! Otherwise, it is difficult to compete with others that also offers C# API.

Thanks.

Can somebody explain me why I have to use IVar<T> type instead of standard int or double types
Similar example we have in: https://www.multicharts.com/trading-sof ... Commentary

And where I can find description to DirMovement type. I don't see it in the PowerLanguage.NET help.

Hello MaRCHeW,

Please see #14 of MultiCharts .NET FAQ and Variables in 4.5_Functions_and_Special_Variables of the programming guide.
