Default data corrupted

Getting unable to read or write cached data when opening Ninjatrader8.

When trying to download period of corrupted data, I am not able to do so. Ninjatrader shuts down automatically.

Please help.

Thank you

patrisialobo, we will likely need your files via email support as there is typically not a 'one size fits all' solution for the general 'unable to write cache data' message which you, and others, have experienced. For example, a custom add-on could be causing the issue, or perhaps the cache or the data itself is corrupt, or maybe even you workspace or a window within it is the culprit. Having the unique information that is contained in your log and trace files regarding your specific PC and installation of NinjaTrader is critical most times in identifying the root cause of general error messages such as this one.

With that said, we may be able to learn some things by troubleshooting on the forums. Please answer these general questions:
  • What version of NinjaTrader 8 are you using? Please provide the entire version number. This can be found under Help -> About (Example: 8.0.X.0)
  • Are you able to reproduce the issue in safe mode?
So we can further diagnose your system, please delete your cache and start NinjaTrader in Safe Mode.To enable safe mode, please use the following steps:
  • Ensure NinjaTrader is shut down
  • Hold the CONTROL key and double click the NinjaTrader icon.
  • Keep the CONTROL key held down until you see the Control Center.
  • You can verify you are in safe mode by going to Help -> About.
Once NinjaTrader has started on just the control center, please connect to a data feed then open a new chart with no custom bar types/indicators/templates and test for issues.

If there are no issues on this new workspace, please try opening the previous workspace by going to the Control Center > Workspaces > Choose your workspace.

If there are no issues, restart NinjaTrader normally and test for issues.

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.

Please let me know the results of this test.

If you'd like to get more customized support based on the information in your files, follow Chelsea's instructions to contact us via email. Make sure to include a link to this forum thread and "1906767 ATTN Patrick G' in the email.
