NinjaScript must be in a compilable state to create or edit Strategies error

[markdshark]

So yesterday one of my strategies would uncheck itself when applied in the strategy window. Although the strategy compiled fine and even ran fine in the strategy analyzer the error I was getting was something about accessing an index out of range. I searched the forums and followed some advice to enable debug mode and open the strategy script in Visual Studio where I compiled it, set a breakpoint and reviewed it, then removed it and successfully ran the strategy with no error for hours with no changes made.

Today however again, no changes made whatsoever but when I fire up Ninjascript editor I get the above error and was unable to open any of my scripts. I had however saved the workspace with a few other scripts open and when trying to compile those I get this error:

Source file '\\Mac\Home\Documents\NinjaTrader 8\bin\Custom\obj\Debug\.NETFramework, Version=v4.8.AssemblyAttributes.cs' could not be found. The error code in the next column is CS2001.

I checked and yes, there's no such file.

Besides wondering how I can resolve this issue, my questions is also why did this error start happening? What happens between the handoff to VS Studio 2002 and then closing that solution that now breaks NinjaScript Editor so effectively.

Things I have already tried which have not worked:

1. Making sure the Debug Mode is unchecked on all open scripts and recompiling
2. Opening the code back in VS Studio 2022 and recompiling - it builds fine with no errors but the NinjaScript Editor remains broken.

Edit: now tried building the entire NinjaTrader.Custom in VS Studio and I get 662 conflict warnings CS0436. Pic attached.


Any suggestions?

Hello markdshark,

Attempting to compile in Visual Studio will break NinjaTrader by generating an AssemblyAttributes.cs file.

Do not compile in Visual Studio. Compile only in NinjaTrader's Ninjascript Editor.

The NinjaScript Editor also monitors files for changes. If you save 'Ctrl + s' a script in any editor, including Visual Studio, while the NinjaScript Editor is open, this will automatically trigger NinjaTrader to compile.

Just save the script in the external editor while the NinjaScript Editor is open. Do not compile with an external editor.

To resolve the error delete the 'Documents\NinjaTrader 8\bin\Custom\obj' folder.

Hello ChelseaB,

I'm getting the same error ('NinjaScript must be in a compilable state to create or edit strategies'), on a newly installed version of NT8, and on the first attempt to create a strategy in Strategy Builder.

I'm relatively new to Ninjatrader and unfamiliar with much of the usage terminology. I don't know what "Visual Studio" is, and as far as I know I haven't compiled anything there.

I've also accessed the 'Documents\NinjaTrader 8\bin\Custom' folder, and there is no 'Job' folder in there.

Any suggestions?

Update: I've fixed the problem. It was caused by me bypassing the correct path to import a third party indicator. I had purchased and used this indicator in a prior version of NT8.

After installing the new version of NT8 I wanted to import this indicator but I had lost it's zip file-- so I was unable to import it using the Control Panel/Import/NjinjaScript Add-On path.

So; I bypassed the NinjaScript Add On path and copy/pasted the indicator's .cs & .dll files from the "OLD" NT8 folder into the new NT8/bin/Custom folder.

The indicator worked fine but bypassing the import path in this way apparently caused the error code. After deleting the indicator's .cs & .dll files from the NT8 folder, the error code went away and I can now use Strategy Builder.

That indicator cost me $150 and I really don't want to purchase it again so I'm wondering if there is another way to import it, since all I have of it are it's .cs and .dll files. I'm guessing that the original zip file contained a third/instruction file which didn't save into the NT8 bin/Custom folder.

Does anyone know how to do this?

Hello Jazzman53,

If you can provide the files, I may be able to create an export out of it.

Hello Jazzman53,

Thanks for indulging my inexperience, and for that generous offer to help but I was finally able to zip those files back up and import them the correct way, and everything works now!
