Thanks for your response Jerry,
This is a time chart. As soon as the bar timer gets to 100%, AB
advances the chart one bar and redraws the previous complete bar, then
draws the incomplete new bar, and does not update it again before the
bar closes. The chart is running just fine other than that, updating
the RT data, but nothing associated with changed bar data.
I also have another simpler chart running on the same database. It
runs in 0.05 seconds and has the same behavior.
The market has been slow and steady most of the day.
I just gave Zero a try and no better.
I have a quad 2.8 GHz with 4 GB RAM. The CPUs are barely running, and
they are running XP in a virtual machine. I don't run anything but AB
on my VM. It is clean as a whistle. So, I think I am clean on these
items.
Best regards,
Dennis
