Hello, Precisely. If you actually read API docs: http://www.interactivebrokers.com/en/software/apiReleaseNotes/api_84.php?ib_entity=uk#84_intraday
you would see what are the limits of backfill and that they are set by IB, not AmiBroker. See the table in the document pointed out above. 2000 seconds is maximum backfill length when timeslice duration is 1 second (finest available @ IB). Therefore you can not get more than 2000 seconds in one request when your database is set to Base time interval of "Tick". The only way to get more than 1 day of backfill data is to use base time interval of 1-minute.
