Did the Import process really delete my minute data?

[zacharydw00]

I importing a tick data file for only one day 8/16/2010, to replace a few missing Minute bars. I enabled "Generate Minute bars from imported tick data". As my Historical Data window shows the minute data for 8/16 was created, BUT all the minute data for the rest of Aug. and Sep. is now gone.
My question is, did the Import process really delete my minute data, or is the Historical Data window broken/incorrect? I ask because a 1 minute chart of 8/17 and 8/18 still shows bars.

I did close and restart NT before taking this image.

Don't bother trying to import it yourself, this tool automates it. Been using it for a while, importing fed fund rates, tick data, etc. https://ninjatraderalgos.com/products

Hello zacharydw00,

Can you please send me your log & trace files and .txt file with the historical tick data so that I may investigate and test it on my end.

You can do this by going to the Control Center-> Help-> Email Support.

Ensuring 'Log and Trace Files' is checked will include these files. This is checked by default.

Click in the Attachment field to attach the .txt file with historical tick data.

Files sent.

Things are getting stranger. I took another look at the Historical Data window, and now all of Aug. is missing. But, I can open a minute chart of the first 2 weeks of Aug. 2010 and the data is there.
