Any updates on this topic?

Is this project still being worked on, is it dropped?

IQFeed Developer Support » Java API + IQFeed Wine Jun 17, 2013 06:31 PM (Total replies: 5)


Well, this just to share my thought.
I have to admit, that I expected a direct and simple reply when I asked this
as most tools nowadays have free support forum, so one normally expect to get a lot
of help from non paid support

The main reasons I didnt follow up are
1- getting the API is more of a long term plan or idea for me, i am not in a hurry
2- I am expecting the answer to be a 'Yes" and I asked to just get a confirmation
3- luckily for IQfeed, they dont have a lot of competition for the price of the feed, so if i ever reached the point of having to use the API directly, I would have had to work around any limitation ... so Cpratt, if you need the API, you really dont have that many options

best regards to all

IQFeed Datafeed Wish List » R connectivity Nov 14, 2012 05:00 AM (Total replies: 8)

I also found out about seer

which hooks to R and can use IQFeed
I never used it, but it was praised by few on the elitetrader forum

What I understand, you dont need to pay extra to use the API
You pay the ~300 annual fee to get support and notification of updates, sample code, stuff like that

So if that github library works, you can just use it

Personally, I strongly recommend you look into charting application that allow you
to program your own indicators or studies

check amibroker, sierrachart, ensign, multichart ... and the list goes on

i cant recommend you use R if you dont already know it. if you will learn something new to
program your own indicator or studies ... learn to use one of the applications i mentioned above
you will pay extra for the package, but you will get much better support

R is not a fun language to learn or use .. according to my very very short experience with it

well, i dont know R

but check this link

i think it can help you, my conclusion would be that connecting to iqfeed from R wont differ much from connecting to it from any language using the tcp interface

also check this link

many articles about using R in trading or trading analysis

IQFeed Developer Support » Java API + IQFeed Wine Sep 23, 2012 07:18 PM (Total replies: 5)

Will I be able to use the Java API to connect to IQFeed if its running under wine

I understand (from other posts on this forum) that most people who run IQFeed under wine
just connect using the socket interface using any language

But would there be any benefit (or disadvantage) using the Java API provided by IQFeed?

Any updates on this topic,

IQFeed Developer Wish List » Platform Independent Java Version Aug 9, 2011 07:14 PM (Total replies: 10)

Greeting all,

I noticed mentioned in some older post (2010) by telvent moderators that a Java version of iqfeed is being worked on, but still in very early development

Is the Java version still being worked on? Is this initiative still alive? When can we expected a release 2011/2012?


IQFeed Developer Support » Socket Interface Documentation Feb 26, 2011 03:50 PM (Total replies: 3)

Thanks Jay for your prompt reply.

I just installed IQfeed under Wine/Linux, it seem to work, I was able to

> telnet localhost 5009

which i took as a good sign, it keeps sending records that look like this thought

I am not sure what this mean.
I hope I didn't break anything! If you can explain this please do

The next step for me would be to buy the developer registration to receive the full docs, I think I would need anyway no matter which route I decide to go

thanks again.

IQFeed Developer Support » how to insert large amounts of data Feb 25, 2011 06:13 PM (Total replies: 1)

This is a bit generic,
but when writing to a DB the only way I know of to make things faster is to use transactions and commit every 1000 or 10,000 or so rows, this is how its done for ETL jobs.

If you are using mysql you may also look into using their multi-insert insert into syntax
>> INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);
(copied from )

Also consider if possible dropping any primary keys and indexes constraints before the insert and building them afterward

IQFeed Developer Support » Socket Interface Documentation Feb 21, 2011 04:27 PM (Total replies: 3)

Where can I read or download the socket interface documentation?

I searched the IQfeed, but only found the quick start guide which wasn't really helpful
I intend to use it under Wine / Linux, so if anyone can also share examples in Perl or Ruby, that would be great too, as I will also be learning socket programming as I go

From what I collected online, I believe I will connect to a socket on the loopback IP and port 5009.

And that I should be able to send messages to query the feed, so I believe the documentation should include the message formats like how to specify a symbol or symbol list, a date range, how to request for delayed vs historical vs real time, does this detailed documentation exist somewhere?
