UNABLE TO WRITE CACHE DATA ERROR

How to fix  NT8 error " Unable to write cache data ":

1-DELETE CACHE

1)  Please delete your cache, hide your locally stored historical data

Follow the steps below to delete the cache and hide your historical data.

  • Shut down NinjaTrader.
  • Open the Documents > NinjaTrader 8 > db folder.
  • Delete the sub-folder named 'cache'.
  • Rename the 'day', 'minute', and 'tick' folders to 'dayOLD', 'minuteOLD', and 'tickOLD'.

2- 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 open a new chart with no custom bar types/indicators/templates and test for issues.

If there are no issues with 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 problems.

If this reintroduces issues, I would suggest rebuilding your workspace.

4- REBUILD YOUR WORKSPACE:

- adding 1 indicator at a time.
Please keep track of what indicators you add back in so that we can narrow down which indicator is causing the issue if it returns.
