Hi, Patrick,

I follow your instruction and problem still exists, please see attached picture for more information. I create a new workspaces and shut down Ninjatrader, then delete cache folder, then restart Ninjatrader and open a new chart, only add Order Flow Cumulative Delta indicator, and problem still exists on the same time(11/27). What do you think if I re-install Ninjatrader ?

Thank you.

I can't reproduce this issue on my end, so we need to troubleshoot further to find out what is unique on your end that is causing the gap in your chart.

Can the issue be reproduced on a new chart window with no custom add-ons or templates? Just the data series and Order Flow Cumulative Delta (like my screenshot)?

If so, please clear your cache and then test:

• Shut down NinjaTrader.
• Open the Documents > NinjaTrader 8 > db folder.
• Delete the sub-folder named 'cache'.
• Restart NinjaTrader and test.

Still persist even use reload all historical data.

If you right-click on the chart and select 'reload all historical data', does the issue persist?

Hi, PatrickG

I am using 8.0.16.3 64-bit , but I remember previous version also has same issue.
Data source is Ninjatrader continuum.
I never saw any error message on screen or log about this issue.
Always happened around midnight, but I have never seen it happening, only when I run program and found data missing again on last day.
Seems only happen on NQ, I just checked ES/RTY/6E using 5 min. data and serveral days, only NQ has problem.

Thank you.

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.X)

Who are you connected to? This is displayed in green on lower left corner of the Control Center window.

Does this occur on any other instrument? Or is it isolated to the NQ?

If I am reading your chart correctly, this occurred right around midnight on the 26th/27th GMT+8? Are there any steps you can take to correct the issue? Or do these gaps remain regardless of any efforts to correct it?

Do you receive an error on screen? Are there errors on the Log tab of the Control Center? If so, what do these errors report?

Why is order flow cumulative delta randomly missing data around 23:00~24:00 (GMT + 8), not everyday, sometimes start from 23:10 and sometimes from 23:30. Thanks.
