AB only stores data that is there. If there were no trades for those
times then there will not be any data stored.
AB shows what data there is on the screen, so if no data then no bars.
If on the other hand you knew tha there were trades at those times
then it means that AB did not import the data. I run a scan over all
the stocks to make sure that AB imports the data. I also turned off
theoptimised retrieval of data in the databse settings as this limited
data im porting to the most recent in QT and not all of the days data.
