"I just wanted to say how happy I am with your service. I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email

IQFeed Developer Support » When was the market center field deprecated? Jul 28, 2010 03:14 PM (Total replies: 1)

Can somebody tell me exactly when field 26 of the update message (market center) actually stopped having valid data? Also, I'd like to know when it was deprecated?

Thanks, r.

IQFeed Developer Support » Ordering of concurrent update messages Jul 28, 2010 03:11 PM (Total replies: 1)

Hi, I'm wondering what I can assume about the original ordering of update messages with the same timestamp. I can see a few options:

1) no ordering can be assumed
2) updates from each market center are ordered with respect to each other only, however, trade, bid and ask updates must be computed separately based on the update type and the appropriate market center code (fields 63-65)
3) all updates are ordered correctly

Any ideas?

Thanks, r.

DTN.IQ Client Software Support » Unable to re-use a historical socket for requests Jun 10, 2008 03:38 PM (Total replies: 2)

That works. Sweet, thanks!.

DTN.IQ Client Software Support » Unable to re-use a historical socket for requests Jun 9, 2008 04:17 PM (Total replies: 2)

If I make a request using the TCP/IP interface such as "HT,ESV,1;" I will get the correct data terminated by an "!ENDMSG!" line. However, if I send another request on the same connection such as "HT,RIG,1;" I immediately get a "!SYNTAX_ERROR!" response. This occurs both within my Java program and from a telnet session.

Has anybody else seen this problem? Any ideas what could be going on?
