Hello,
in the meantime DTN has officially released new versions of the
IQFeed API. The current live release is IQFeed 4.0.0.2. It is now
an official release and no longer in beta testing stage.
Apparently the backfill problem got finally fixed with the new API
version.
Can we Amibroker IQFeed users expect an updated version of the
Amibroker IQFeed plugin, Thomasz?
