Hi,
I had a hard time with Amibroker and IQFeed support, both being
useless. Although they both tryed their best. I think it is
Amibroker to blaim otherwise IQFeed would have been out of business.
You are right that when I restart AB all thata gets filled correctly,
but it is ONLY in that moment when it starts. From that moment on
the chart is not updating unless I do "force backfill".
I have AB installed on my laptop and my desktop and I get exactly
the same problems, with exactly THE SAME symbols.
My chart timings are less than 0.01sec so no problems here.
I also have some delay in the datafeed, it varies from symbol to
symbol but it is in the order of a few seconds, usually no more than
5sec. I think this could be because IQ servers are in US and I live
in UK. I am not happy with that delay but at the moment I have
bigger problems than that.
And most symbols are updating correctly but to me it makes AB
useless for day trading if I can't see the volume or the chart is
completely frozen.
I get all sorts of other problems with AB detabase, like each symbol
backfills to a different historical date. For example BRCM has
quotes going 31 days back while RIMM only 20. And that all is with a
database setting of 72 days.
I did try to delete the database, create a new one and backfill it
with data but that doesn't help.
