[amibroker] intraday data missing bars



PureBytes Links

Trading Reference Links

I use QuoteTracker plugin to import intraday data and notice that, for
some stocks, especially the ones are not actively traded, there are
often missing several bars in between.
For example,(just an example)
FFIV	11/29/2005 9:48:00 AM	52.15	52.19	52.19	52.1	2100	
FFIV	11/29/2005 9:47:00 AM	52.18	52.11	52.3	52.11	10574	
FFIV	11/29/2005 9:45:00 AM	52.19	52.13	52.22	52.01	8892	
FFIV	11/29/2005 9:44:00 AM	52.17	52.18	52.23	52.14	3499	
FFIV	11/29/2005 9:42:00 AM	52.22	52.2	52.25	52.12	10782	
FFIV	11/29/2005 9:41:00 AM	52.23	52.19	52.23	52.18	4003	
FFIV	11/29/2005 9:38:00 AM	52.19	52.23	52.23	52.19	1100	
FFIV	11/29/2005 9:37:00 AM	52.23	52.25	52.25	52.11	7200	
FFIV	11/29/2005 9:36:00 AM	52.25	52.35	52.37	52.1801	4519	

There is no data for the periods 9:43:00 AM, 9:39:00 AM and 9:40:00 AM.

My questions are:
1. Do you think the row for 9:41:00 AM cover all the missing period
from 9:39:00 AM to 9:41:00 AM?

2. Is amibroker able to handle the situation like this where there is
missing bars? in other word, do I need to repair the data with the
missing bars?

thanks,
