I can't reload all historical data of my Renko chart (future FTI 05-16) anymore. It's greyed out.
I am now missing yesterday 17-5-2016, this day I didn't have NT7 running that day. But the previous week I also could not reload historical data.
However, in all my other charts it is still possible to reload historical data.
I already tried a
- restart,
- disconnect/connect
- load smaller Renko and then back to larger Renko
- load 5 Minute and then back to Renko
- and a DB repair
but so far no cure.

How can this problem be solved?
