Missing dates

[flexi]

Hi,
I am experiencing some missing dates in my ES minutes chart. I have history imported
since 2003 and everything is fine but some times there are missing dates. As can you
see from the picture bellow dates from 6.5.2003 until 6.13.2003 are simply missing
on the chart although they are imported and I can see them in historical data manager.
The thing is that the future for 6-03 contains all the dates until 6.11 but they are not displayed.

Any solutions?

Hi flexi would rollover dates have you setup for those older expiries? Per default NT would only have the contracts going back until 2005 setup. So I would check how you have defined the prior expiries here.
