Can a strategy or indicator have more than a single source file?

[alex.nt]

Sorry, probably this question is already answered but I could found it through the search.

Is it possible to have multiple sources for a strategy/indicator?

Thank you.

Hi Alex, what would you mean please by mutiple sources? Do you mean data series / instruments?

[alex.nt]

Hi Bertrand,

No, I mean multiple cs files. For instance, to use partial class definition or even different classes, because sometimes strategies get quite big for a single source file.

I see, strategies could not call other strategies, but you could call for example methods from UserDefinedMethods.cs or other indicators of course.

Can I use partial class definition for an indicator/strategy? Can I use a non-indicator class from within a separate cs file?

I mean, there must be ways to split the code of an indicator/strategy into several files.

ninjascript is all C#. just create your custom namespace and do whatever you like. Strategies/Indicators are partial class by itself (see UerDefinedMethod.cs file).

yes you can use multiple C# files and partial classes.

Only limitation are Indicator derived classes. For these Ninja generates a custom script a the bottom of the file. Having 2 source code files for the same indicator derived class will probably mess that mechanism up. But try it, as you will see errors at compile time.

I guess a little example would be helpful. I will try to split the code into different cs-files and hopefullt report the results here.

Did this ever get resolved? Seems like a pretty straightforward request/need. Not sure I have ever written a C# program in just one source file. Multiple source files for a single indicator in NinjaScript may not be possible, as I sure don't see a File/New option anywhere. Am I missing something?

For full disclosure, I am using the demo version. The features this thread addresses may be available in the paid version. It would be nice to know if this is the case.

When you write a NinjaScript class, you are writing an object to be used by the NinjaTrader program: you are not writing a program.

I do not know of any language which allows you to write a single class in multiple files, unless you use partial classes. Ninjascript does allow that.
