Cannot Open NT8

[jpkulkarni]

So I was making changes to my strategy code and the compiler was stuck for sometime. I ended up closing al the windows and then finally had to kill the NT process to exit the app. In past when I had done this (the compiler getting stuck without any error is really painful).. restarting had worked for me. This time, I am getting below error. I get couple of these prompts and then NT exits without starting. I tried to rebuild the solution in Visual Studio but its not useful. Still cannot start NT.

Please help.

Hello jpkulkarni,

Delete the Documents\NinjaTrader 8\Config.xml file and uninstall and re-install NinjaTrader and you should be able to launch NinjaTrader and correct any reference or compile errors in the NinjaScript Editor.

Note, the error will still appear, but NinjaTrader should launch.

I had a saved copy of the bin/Custom folder that I restored and tried to add back my indicator.. It is doing the same thing (aka infinite loop of compiling without any errors).. Anyway I can see the output of the compiler?

Also if I re-install NT then does it change my Machine ID? Will I need to get (aka pay for) licenses for my already paid indicators/strategies again?

Hello jpkulkarni,

Once NinjaTrader is started open the NinjaScript Editor, right-click and select compile. This will show the compile errors.

Re-installing NinjaTrader will not change the MachineID but other factors can cause the MachineID to change.

Ok.. I have tried uninstall, reinstall and resetup NT8.. There is literally nothing in this new NT8 installation other than 1 custom indicator code that has been working till this afternoon and I didn't even make any changes to it for it to stop compiling.. Any new suggestion on why the compiler keeps running without any messages etc.. These all processes/threads running under NT.. What is the blank one? Is that normal ?

Also everytime this happen I get Pacing Violoation and then connection lost message in Log



I am pretty sure its not my code but something else.. Sincerely appreciate pointers on how to get to the bottom of this..

Hello JK,

The long compile times are being experienced by other developers and is something our development team is working on.

Below is a link to a forum post with a discussion.

https://forum.ninjatrader.com/forum/ninjatrader-8/add-on-development/1280116-version-8-1-2-freezes-chart-and-keeps-compiling-forever

May I have you send an email to scriptingsupport[at]ninjatrader[dot]com with a link to this forum thread?
I'd like to investigate further with you.

Thanks Chelsea. I am good for now. FWIW, i have noticed that slow compilation (aka never-ending compilation) completes after I close Script Editor, Output Window and Visual Studio. Frustrating but I can live with this workaround till the team figures out a permanent fix. Also if it helps, I am using a VPS with AMD processor.. in case that is an issue.

Alright.. Cannot start NT8 again. The last message it gave me was "unhandled exception trapped" - not enough memory resource available to process this command. Under Documents\Ninjatrade 8\trace folder I found a file with following error. I have not been able to start NT8 since. Here is all I have done

1/ Tried removing Config.xml
2/ Tried removing obj and bin folders under Custom
3/ Tried removing Cache folder
4/ Tried removing db folder

Still cannot start NT8. Please help. I just installed this 2 days ago based on above issues.

Finally - i am not sure why this is a memory issue. I am running on 32GB machine and i barely see NT using more than 2-3GB. If my code has issue, I should see memory usage go up but its not something I am noticing. Also not sure why it cannot even load now.

Can I downgrade to last stable version? These issues are really slowing down progress.

Please help.
JK

2024-02-27 18:54:02:616 Shutting down NinjaTrader​

[NinjaTrader_ChelseaB]

Hello jpkulkarni,

Have you tried starting without a saved workspace?

To start without a saved workspace:

• Shut down NinjaTrader
• Navigate to (My) Documents\NinjaTrader 8\workspaces
• Select all files in this folder -> right-click one of those selected files -> select Cut
• Navigate to the Desktop -> right-click the Desktop -> select New -> Folder
• Open this folder -> right-click in the folder -> select Paste
• After moving these files, restart NinjaTrader which should startup without any workspaces
• Once NinjaTrader has started on just the control center, please open a new chart using 1 minute bars and try reproduce the behavior.
  Do not load a template on this new chart or any 3rd party indicators.
  
  * Please note this will not delete your existing workspaces. However the new blank workspace will be named Untitled1. If you have a workspace already named Untitled1, rename the workspace in the Workspaces menu by clicking Save As > and give a name for the workspace like TestingWorkspace. Then do not save Untitled1 when shutting down NinjaTrader (otherwise it will overwritten).

Please let me know if on this new 1 minute chart if the behavior continues when all other workspaces are closed.

[jpkulkarni]

Thanks Chelsea. That worked. Sincerely appreciate quick response.
