My experience with DTN is that DTN cannot fix problems.
Evidently they do not employ capable code writers on their regular staff, and
for some reason are reluctant to employ outside help.
Whatever the real reason is, it is more likely that you will
have changed data vendors by the time they will have the problem
fixed.

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.

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.
