I'd say it's not a bug, but simply the conceptual design of Amibroker.
Amibroker's ability to run more than one instance at a time is already
a powerful feature compared with other charting programs.
It would be an interesting question, whether (and how) the conceptual
design could be improved, in terms of how databases are handled.

We have to distinguish here between
(1) missing features, data quality issues etc. of IQFeed
(2) bugs in the IQFeed API or IQFeed client launcher programmed by
DTN, and related things such as implementation, conceptual design
issues or inadequate API documentation.
(3) potential bugs in the IQFeed plugin programmed by TJ
I too would appreciate very much if the "Open & Low = 0" problem of
the IQFeed plugin could be fixed. As charts based on histories with
daily bars were correctly displayed by the DTN charting application, I
assumed that it could probably a problem out of category 3. But I
have not yet purchased the IQFeed API yet (will perhaps do if DTN
implements the bad tick filters).
