Strategies in NT8 operate in the same AppDomain

[roblogic]

Hello,

I would like to know if custom Strategies in NT8 operate all in the same AppDomain? I am wondering as I would like to know the behavior if I create a static field in an AddOn partial class Strategy. Will the static field hold the same value across all instances of my custom strategies ? Thank you.

Hello roblogic,

Thank you for your post.

Yes, they get compiled in the NinjaTrader.Custom.dll when open source or when it is included in an assembly.

I would like to know the behavior if I create a static field in an AddOn partial class Strategy.

Static classes are possible, however please note that we generally advise against using them, as using a static property to share information between scripts could break during backtesting / optimization.

That said, we do have an example script demonstrating static methods within a partial class. Please note static classes and methods are not officially supported:
