Call C/C++ DLL Functions from within my NinjaScript NT8 Indicator

[BlakJak888]

I have been trying to find out if it is possible to call C/C++ DLL functions from within NinjaSript.

I know it is possible from C# but after doing some Googling, I am seeing mixed messages on the subject and most posts are very old.

Does anyone know if this can be done, and if so, is the process exactly the same as doing it from C#?

Hello BlakJak888,

Welcome to the NinjaTrader forums!

From my understanding this is possible, but please note this is outside of what is supported by NinjaTrader Support.

The assemblies will need to be PInvoked using DllImport. (It will not be able to be referenced like a managed C# assembly)

Below is a publicly available link to the microsoft documentation.

A publicly available link to an educational site, StackOverflow.

And a link to an example.

Thanks. I am glad to hear that it is possible since the internet was extremely vague and had differing views on the subject. I can handle the coding provided the platform will accept the external calls to the DLL.
