    common DLL for multiple indicators

    Hi!

    I am developing different Indicators (NT8 - I am using VS2019 launched from within the NT Script window), but have some methods that I do in all of them and am trying to figure out how to put these method in a separate class/DLL.

    It seems that I cannot just build a DLL and point to it Dependencies. Nor just put it in the \Documents\NinjaTrader 8\bin\Custom folder?

    Also I am aware of that I need to add the DLL into the distribution .zip (https://ninjatrader.com/support/help...tml?editor.htm) once I shall distribute.

    Does anyone have any direction to point me towards other than the helpguides?

    Appreciate any feed back, thank you.
    Regards K

    Hello Trasss_Kenneth,

    Welcome to the NinjaTrader Forums.

    You could consider using static methods in a NinjaScript AddOn. See the MySharedMethodsAddOnExample script in the forum thread below which demonstrates creating static methods in an AddOn.

    Let us know if we may assist further.

      You could create your own abstract base class,
      something like MyIndicatorBase, and put your
      common code in there.

      Study this example.

        Thank you very, very much for the two very useful yet different approaches

        Just did some testing with both - AddOn works fine but the abstract approach(which I find most suitable) gives me an issue when creating my own abstract indicator - when NT compiles the code it adds the "neither change nor remove" code, which it does not do on Strategies - any ideas?:

          Exit NinjaTrader

          Using a different editor, go into the abstract base class file and delete that code.

          Start NinjaTrader

          Try compiling a different file, something other than the abstract base class file.

          Does it still generate the wrappers?

          Can you attach your code?

            Also, try moving your abstract base class file to the Addon folder ...

              Hello Trasss_Kenneth,

              Thanks for your note.

              Abstract classes are a C# concept. There can be limitations when using advanced C# concepts in NinjaTrader.

              As of now, we do not have any documented or supported examples that can be used to navigate this path.

              You may find using partial classes to be helpful. See the attached reference samples demonstrating using partial classes.
