I'm just
speculating here. But all minute bars are made up of tick data, compressed
to the time period you select. There are cases where in a slow marketa
stock may not have any activity at all during a particular time frame, say 1
minute. So I would imagine there would be no ticks to make up a bar.
In this case, there should be an empty space between bars which represents no
activity.

If your data came
in 1 minute bars as opposed to tick data, then I would imagine the chart is
going to zoom down to zero when it hits that data.

Good
question about how Amibroker handles this.

Time Data - IntraDay Data Question...I was wondering
how AB treats no trade records for a giving time interval. For
example, a kind donor of 1 min QQQ data from 1999 to present from QCharts
in ASCII format had record in it with Date, Time, 0, 0, 0, 0, 0.
Each zero representing O,H,L,C,V for a time interval where there wasn't
any activity.Some software place the previous trade record's O,H,L,C
and V...thus distorting all indicator calculations...so How can we filter
these records from an importing data point of view and how does AB treat
real time 1min (for example) bars if there aren't any
trades...Thanks Your
