NT app has stopped working

[gbrad]

Hi,

I'm getting the following message on startup of NT7:

NinjaTrader application has stopped working.
A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.
< Debug > < Close Program >

I just finished programming an indicator and NT crashed right after I inserted on to a chart. I'm pretty sure that caused the issue...I could see the memory spike up to 2g.

How do I go about getting back up and running?

Thanks,
gbrad

NinjaTrader 7 Application Stopped Working

Good Morning,
I received the same message today (Jan.9.18). I already sent all my Log and Trace files in a zip folder to platformsupport(at) ninjatrader (dot) com before reading this message.

The email was sent today.

Please advise if you received it.
Many thanks

To any future readers of this post, this error message can mean almost anything and it would be impossible to troubleshoot without further information. Please make sure to follow Drew's instructions to write into our support email so we may assist you individually.

Valdon, I do not see an email in our ticketing system from the email address which you used to register your forum name. Please make sure you're replacing the [AT] and [DOT] with the actual symbols. We write the email address this way in an effort to prevent spam emails.

So, to clarify, make sure to insert a ',' for [DOT] and '@' for [AT] when writing to:

How this issue was resolved

Valdon,

Below is the instructions that Drew sent me to resolve this issue. I only had to follow the steps regarding the workspace to get things working again.

Regards,
gbrad

I see that you're running an older version of NinjaTrader 7 and that this is occurring when a few workspaces are loaded. The newer version contains many critical updates to the database.

I would advise that you upgrade and then test without a workspace. Finally, I recommend you reset the instruments as a troubleshooter.

First, to upgrade NinjaTrader, please follow the steps below:

First get your license key from NinjaTrader under Help> License Key then exit NinjaTrader
Click on the link: http://ninjatrader.com/PlatformDirect
Enter your license key and press Submit
Select 'NinjaTrader 7'
Select 'Download'
Critical: Before running the installer, ensure NinjaTrader is closed.
Once done, as a test, please take the following steps to force NinjaTrader to start without your saved workspace. You will have the option to reopen these after our tests.

Shut down NinjaTrader

Navigate to (My) Documents\NinjaTrader 7\workspaces <--This Here

Delete the file named "_Workspaces.XML". DO NOT delete the 'workspaces' folder - only delete the '_Workspaces.XML' file within the 'workspaces' folder

After deleting this file, restart NinjaTrader which should start up without any workspaces.

Once NinjaTrader has started on just the control center, please open a new chart with no custom bar types/indicators/templates and test for issues.

*Please note this will not delete your workspace however the new blank workspace will be named Untitled1. If you have a workspace already named "Untitled1," however, you will not want to save the workspace when exiting NinjaTrader, otherwise, it will overwrite it.
If there are no issues on this new workspace, please try opening the previous workspace by going to File--> Workspaces--> Open workspace.

If this reintroduces issues, I would suggest rebuilding your workspace, adding 1 indicator at a time. Please keep track of what indicators you add back in so that we can narrow down what indicator is causing the issue if the issue returns. I also suggest making a backup of your workspace so we can restore a backup if the issue returns.

I have provided a link below to our Help Guide that goes over backing up and restoring.

http://www.ninjatrader.com/support/helpGuides/nt7/index.html?backup__restore.htm

Lastly, to reset your instruments, please follow the steps below:

Disconnect from your data feed: NinjaTrader Control Center> File> Disconnect> Select your data feed
Reset your Instruments: NinjaTrader Control Center> Tools> Options> Data tab> Reset Instruments>OK
Restart NinjaTrader> Connect (NinjaTrader Control Center> File> Connect> Select your connection
Please let me know if you continue to experience the same.
