Thought I'd chim in since I have both right now.
I must admit that for pricing reasons I have been trying to move all
my subscriptions to IQFEED for over a year now. I previously had a
ton of problems w/ the prior IQFEED link to AmiBroker but that seems
to be working better since a new IQFEED adaptor was released by
AmiBroker in the fall.
Here are the two items I consider major issues:
1. you can not have a mixed database unless something has changed.
Therefore you can not see longer term charts on daily or weekly basis
in the same database. Maybe this has changed or will change.
2. despite repeated requests to iqfeed (see their user board) their
backfill is substantially slower then esignals backfeed; or at least
it appears that way because esignal backfills from the current day
back, so you see the current day on the screen whereas iqfeed
backfills forward so it appears to take much longer. if have so far
found it too annoying when I want to backfill a bunch of stocks.
I'd very much like to switch to iqfeed but those are 2 major issues
for me.
