OK thanks Tomasz. Maybe it is hopeless then to wait
for IQFeed and I will consider switching to eSignal as well.
Also IQFeed told me that they would implement the
"second stamp" to their data in the spring. I don't think it has been
implemented yet.

Subject: IQFeed has now the status of
unsupported beta until the release of API 3.0 was: Re: [amibroker] Re: IQFeed
Problem; Open & Low = O for last day
Ed,
Frankly speaking IQFeed API is populated with "issues" that
I have reported to IQFeed staff ONE YEAR ago.
NONE of those "issues" were fixed till now. I have
heard lots of promises from IQFeed that they will bring
API 3.0 that is supposed to fix the problems for months but
no upgrade was released for one year now.
I have really way more important things to do
than
trying to implement tens of workarounds that only partially
fix problems in IQFeed.
If you say that QT works with IQFeed correctly then you are
wrong. I have QT running too and it experiences
the whole bunch of problems running with IQFeed (especially
problems with logging in, with working in multiple
application mode, with disconnections, bad
ticks, etc, etc).
If you got the access to the IQFeed developer group you will
see HUNDREDS of developers pointing out the SAME problems
with IQFeed.
For that reason effective immediatelly I change the
status of IQFeed plugin.
Current status of IQFeed plugin is "UNSUPPORTED BETA" and
will remain so until DTN IQ staff releases the IQFeed
API 3.0
that was promised one year ago.

Hi Brian,
I can understand your
frustration and I am not yet very happy with how IQFeed works with
AB either. What I understand from Amibroker is that IQFeed does not
really cooperate but I let Amibroker comment on that. Thing is that
IQFeed does not provide the dll files, Amibroker does. The
errors you see are due to errors in the Amibroker dll file.
If this is caused by the fact that Amibroker is not getting sufficient info
from IQFeed I don't know but Amibroker told me that fixing the problems
has low priority because there are only 6 IQFeed users.

Further I am not a specialist on
these matters but I made several databases next to each other and never have
problems. When I had my eSignal trial I had a database based on 1-Minute and
a database based on "tick" data. If I wanted to use the ticks I just
switched to the other database. So<FONT face="Courier New"
color=#0000ff> I do not really understand why you have these problems.
If you make a database for IQFeed and you make a seperate database for
Lycos EOD then you should be able to switch from one to the other.
I think maybe you should address
your questions to <A
href="">support@xxxxxxxxxxxxx
Herman v Bergen has mentioned
the problem about not being able to use historical EOD data (of for
instance the Lycos database) to incorporate the data inside the intraday
database in order to calculate 200 EMA etc. See his posts for the
solution they came up with. It is not an easy solution I believe ....
it involves work ....
<FONT face="Courier New"
color=#0000ff>
But I have to say
that IQFeed only provides the data. They have a charting package as
well but you have to pay extra. I think the data they provide are OK
but the way Amibroker treats them is not OK yet. If this is
because Amibroker does not get enough or proper information from IQFeed
I don't know. But eSignal does not come with any documentation for Amibroker
as well so there is basicly no difference in that respect. eSignal is also
just a dataprovider. Documentation on how to use these data inside Amibroker
is not the responsibility of IQFeed or eSignal it is the responsibility of
Amibroker. If Amibroker offers their program to work with IQFeed but that it
doesn't work properly in practice it is not the responsibility of IQFeed in
my opinion. If the reason that it does not work properly is caused by IQFeed
then Amibroker should not offer it to work with their program. But
QuoteTracker also offers their program to work with IQFeed and apparently
this seems to work fine ...
So I am waiting for an upgrade
of the IQFeed plugin which Amibroker will provide in the future. I notified
Amibroker about several problems: 1) the scan or explore rarely completes
and gets stuck during a backload 2) the newest plugin had a real strange
problem of plotting the same sequence of numbers on the chart without
stopping. These are my main problems. Further it would be nice to have some
way to reduce the spikes in the chart because some charts are unreadable due
to all these spikes.
I tested eSignal and IQFeed and
the data of IQFeed come in just fine. The advantage of eSignal is like I
mentioned earlier: 1) the eSignal chart shows pre and afterhours data 2) the
backloaded data of eSignal are stripped from spikes.
good luck,
rgds, Ed
<FONT
face=Arial size=2>1) You cannot create more than one unique
database in AB as long as the database accesses IQFeed. This means you
have to choose between a unique EOD database, or a unique intraday
database, but not both (and I am not suggesting combining these two
databases into a single database, here).2) I tried using a free
Lycos EOD feed to use with a unique EOD database in AB, but as long as I
have created a unique intraday database in AB setup to use IQFeed, I
cannot access the Lycos feed for EOD data. It may work the first time,
but if you shut down and try it again, it will not work the second
time.3) IQFeed is limited to 35,000 1-minute bars (24 days) or 1,000
daily bars (choose one of these, or choose hourly, 15-minute,
weekly, etc.). The 24 days worth of 1-minute data makes it difficult
to use 200-day or 50-day MAs (not enough data). Since you cannot use
an EOD database alongside an intraday database, you essentially
cannot do any reasonable EOD indicator analysis if you already have
created a unique intraday database. In essence, the best approach
seems to be to use 1-hour or 15-minute data, although that may be
too confining as well.4) I created a unique AB EOD database with
IQFeed, using 200 symbols. I created another AB intraday database with
IQFeed, using 300 different symbols (200 + 300 = 500 max symbols in
IQFeed). Since IQFeed does not allow multiple databases, the test
failed.All of this left me with a bad taste in my mouth. First off,
I can't believe none of this has been previously documented, anywhere,
by the IQFeed service. In addition, IQFeed's DLL files have a tendency
to corrupt AB when you test certain data scenarios. This means
repeatedly uninstalling, and then reinstalling AB and related
components, in order just to test the limitations of IQFeed.
Nevermind losing all of your custom charts and layouts in the
process, since a full AB reinstall (i.e., a complete deletion of the
previous install) won't understand your backup chart and layout
files for whatever reason (someone smoking too much crack?).I
feel IQFeed is probably a good deal for the money, but without proper
documentation the service is a complete and absolute waste of time. If
everyone has to go through what I just went through to understand the
real limitations of the service when it's used with AB, there are going
to be a lot of ticked off IQFeed customers. Time = money. You'd
think the IQFeed people would figure this out and use this high-level
conceptual thought in their basic product marketing strategy. Monkeys
behind the wheel, over there, apparently. Got any over-ripe bananas I
can chuck at their freakin' hollow heads?Let me know if anyone
can confirm any of my findings. I was using the IQFeed.DLL plugin
version 1.4.1 with IQFeed client version 2.2.7.2.Spending the
$100 or $150 a month for eSignal (500 symbols) is probably entirely
worth it, based on what I am finding with IQFeed. Send BUG
