class libraries and NinjaScript

[andrewbee]

Hi,

I am considering porting a large, object-oriented Java ATS to NinjaScript.

My main question is, does the script editor support compiling and linking many classes each in their own source file? (Good) Or do you have to cram all classes used by a strategy into its source file (Bad). Or can you write the supporting classes in an external tool such as Visual C# Express and link to them from the strategy?

Thanks

You can do what you want, but it is unfortunately outside the scope of what we can support. Visual C# Express is not supported. Visual Studio Standard or higher versions are compatible.

So the built-in editor does not support multiple compilation units for a strategy?

[NinjaTrader_JoshP]

Cross strategy communication is beyond the level of what we can support here on the forums.

[andrewbee]

I'm not talking cross-strategy, just splitting up the functionality into multiple classes. Yay or nay?

[NinjaTrader_JoshP]

Unfortunately we cannot support this level of programming on the forums. Just give it a try. You will see what works and what does not work. The editor is a very powerful editor and you will find it to provide a lot of flexibility in all areas.

I'm just talking about using OOP, which is intrinsic to the language that NinjaScript is based on. It's as advanced (relative to the language) as the GOTO statement in BASIC. Do you honestly not know the answer? Does anybody here know the answer??

andrewbee,

Please understand the nature of these types of questions. From our experience they quickly spiral into areas of OOP that we just do not have the bandwidth to support. As such we leave it up to the user to try.

Since you have been persistent in trying to get a yes or no response and I understand where you are coming from so the answer is yes, you can create your own classes. Unfortunately this is to the extent in which we can assist you in this matter. Good luck.

andrew,

It can be done. Do you have visual studios?

breaking things up into multiple classes in what way?

can you give me some more info?

thanks

How to compile VS Form.cs&LINQ Dataclasses into strategy
mrlogik,

I created a form in the Windows Form Designer in Visual Studio. The form will display in the Initialize() method and then be closed before the actual strategy starts running. Plus, I created Language Integrated Query(LINQ) DataClasses for accessing a SQL Server Database from my custom strategy. How do I go about compiling/including the custom form and dataclasses source code files created in Visual Studio 2008 Professional along with the NinjaTrader assembly/files? I'd prefer to copy and paste files from folder to folder and add the necessary "using" directives as opposed to copy and pasting actual source code into my custom strategy file. I tried copy&pasting the actual files into the NinjaTrader/Custom/Strategy folder but it's not compiling successfully from the NinjaTrader script editor. The files compile successfully from within Visual Studio 2008 Professional. Is there a way to do it all from Visual Studio while allowing VS to handle it?
