Trading Hours Error Message

[dmking]

Recently, when I start NT8 I get a series of error messages - around 4 for various never traded instruments - to the effect, "Unable to load trading hours from file 'liffe gilt futures.xml' system.xml.exception: root element is missing...". there are about 4 error windows for different instruments. I just "x" them to close them, but I don't know why these are showing up.

Any ideas?

TIA

This is a known symptom from a program called 'Acronis' running on your PC. This program accesses NinjaTrader's files and prevents NinjaTrader from accessing them causing the error. Is 'Acronis' running on your PC? Check your Windows Task Manager and make sure to check the 'background processes' as well.

Arrrrrrrrrrrrrrggggggggggggggghhhhhhhhhh!

Yes, it's running... SOAB! Any suggestions for making everyone play nice?

[NinjaTrader_PatrickG]

There are two known solutions and one probable solution. The solution you'll want to try will depend on if you're using Acronis purposefully or not:

• Uninstall Acronis
• Click on your start menu > Type "run" then press enter > Type "msconfig" then press enter > Disable all instances of Acronis services then make sure Acronis does not startup in the startup menu.
• Add exceptions to Acronis so that it does not interfere with NinjaTrader
  • https://kb.acronis.com/content/36429
  • Relevant locations of NinjaTrader files/folders on your PC:
    • Documents > 'NinjaTrader 8' folder
    • Program Files (x86) > 'NinjaTrader 8' folder
  • If you choose this step instead of the other two, please follow up and let us know if it worked or not - we do not yet have confirmation from any users that this resolves the issue.

Patrick,

Thanks for the suggestions. I tried both. Added Exceptions to Acronis. and Uninstalled Acronis. In each case, the behavior persisted. I even shut down Windows Defender and my Main Antivirus program. I believe that the problem lies in NT8. So this weekend I'm going to Uninstall NT8 and reload it. Strange.

This goes along with one of my recent posts where NT locks up and can't be shut down after a period of sustained inactivity. Task Manager shows the Status as 'Suspended'.

I don't know if these are related or different issues.

"Unable to load trading hours from file 'liffe gilt futures.xml' system.xml.exception: root element is missing..."

Should not NinjaTrader fix the .xml files so that they contain a root element?

Would not that solve the problem?

[dmking]

OK, I got everything working, but I don't like the fix because there is no closure.

I uninstalled/reinstalled NT8 and the problem remained. I looked in the Documents Folder for NT8, found the Templates folder and found the 3 files that were causing the problem. Oddly, they were all zero byte files. I had a recent backup of this Template folder and copy and replaced the offending XML files. Restarted Ninja and the problem was solved.

So were the zero byte XML files 'corrupted'? If so, what caused the corruption? Why only 3 files? Why these 3? Was this random? Did something else happen? Was this a ninja only problem?

I'd like an answer on this? Am I the only one to have experienced this?

This is a mission critical piece of software. There should be an answer. Things like this make me nervous.

[NinjaTrader_PatrickG]

Yes, it sounds like you experienced a combination of two issues - Acronis may have caused the XML files to install incorrectly, so a 'soft' uninstall/reinstall likely would have resolved after making those changes to Acronis.

Thanks Patrick,

I think that you misunderstood. The "soft" uininstall/reinstall did NOT resolve the problem. It was AFTER that the problem STILL persisted.

I looked at the template folder and found the zero byte files and manually replaced them. I have been using Acronis for over a year with no problems (maybe a minor one earlier in the year) and the problem popped up out of the blue. Even after completely uninstalling Acronis and doing the "soft" procedure the problem persisted.

I don't think it was Acronis.

[NinjaTrader_PatrickG]

Acronis is known to affect NinjaTrader's files in this exact way and produce this exact symptom. I misspoke previously - the reason the 'soft' uninstall/reinstall does not work, is that the installer sees that the files are there (but doesn't check the integrity of those files) and moves on.
