"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed.

IQFeed Developer Support » Reading feed into app Oct 20, 2017 09:51 AM (Total replies: 4)

I have a very extensive example of reading data from the feed using c#:

Updated, in addition to writing to postgres now can write csv files as well.

IQFeed Developer Support » forex: last always == bid? Apr 17, 2017 12:41 PM (Total replies: 5)

Hi Tim,

That makes sense, in general, but I wonder if there are any brokers who provide a feed of actual trades.

Jay,

Thanks for the clarification. Is there any way to capture actual forex trades?

Zane

IQFeed Developer Support » forex: last always == bid? Apr 16, 2017 02:24 AM (Total replies: 5)

what does last mean?


It appears to me, from some limited exploration, that the high and low values in historical seconds correspond to the max(last) and min(last) values from the preceding second's ticks.

Is that correct? If not what is the relationship?

Tia,

Zane

I've been working on a little tool so I can pull historical data and put it into a postgres database.

https://github.com/zanethomas/IqCommander

It can run as a REPL or execute a series of commands from a text file. Although I am using it for postgres it is, hopefully, very easy to add custom consumers of the iqfeed data as it streams from the server.

IQFeed Developer Support » Problem With HIT Interval Nov 15, 2016 10:53 AM (Total replies: 5)

Thanks Tim,

BTW, I see volume numbers in the HIT data. Are they meaningful and if so what is the meaning?

Zane

PS. IqFeed is awesome, thanks to all!

IQFeed Developer Support » Problem With HIT Interval Nov 15, 2016 10:43 AM (Total replies: 5)

Ah, I wasn't aware of that time limit, for some reason I thought per/second data was available for the past half-year.

Thanks!

IQFeed Developer Support » Problem With HIT Interval Nov 15, 2016 10:27 AM (Total replies: 5)

returns data:
HIT,AUDJPY.FXCM,3600,20161005 155500,20161006 155700,,,,1

does not return data:
HIT,AUDJPY.FXCM,1,20161005 155500,20161006 155700,,,,1

why?

Tim,

Thanks.

The docs really could use some work. :)

IQFeed Developer Support » missing .ffff in forex realtime feed Sep 22, 2016 09:46 AM (Total replies: 9)

Tim,

I think we're getting to the crux of the problem.

I believe the docs indicate that the protocol should be set on the admin port (9300). When, instead, I use 5009 things seem to be working differently, in a good way (iow I now see the expected resolution).

Is that all there is to it?

Zane

Hi Tim,

I believe I'm correctly selecting the current protocol, the server is returning:

S,CURRENT PROTOCOL,5.2,

Tim,

Sorry, I should have given a bit more information.

I'm using the FXCM forex feed. The IQFeed Watch Quote application displays time having millisecond precision, which I assume is coming from the feed and not being fabricated by the application.

IQFeed Developer Support » cannot access developer portal Sep 9, 2016 11:27 PM (Total replies: 2)

I just retried, after having been out for a few hours, and ... it works now. Don't know what changed but I'm happy again.



IQFeed Developer Support » cannot access developer portal Sep 9, 2016 06:00 PM (Total replies: 2)

I go to login, enter my username and password (which are accepted) but then I cannot access developer docs.

Support informs me that I should contact developer support, on Monday, I'm not happy.

IQFeed Developer Support » iqfeed on ubunto Aug 28, 2016 11:48 PM (Total replies: 1)

I have installed https://github.com/bratchenko/docker-iqfeed on an ubuntu server and running the image does result in a connect using my program id. However I am unable to get any response out of 5009 or 9100. Those ports are, according to the documentation, forwarded to 5010 and 9101 respectively. However neither of those ports are accepting connections.

Any help with this? Alternative ways to get the feed running on ubuntu?
