"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum

"My broker in Davenport suggested I give you a try as he uses your service and says its the best." - Comment from Bill via RT Chat

"IQ feed works very well, does not have all of the normal interruptions I have grown used to on *******" - Comment from Mark

"I had always used ******* but for the past 2 weeks have been trying DTN IQFeed. Customer support has been extraordinary. They call just to make sure your problem hasn't recurred." - Comment from Public Forum

"You have an excellent feed. Very few spikes for Spot Forex." - Comment from Public Forum Post

"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob

"I have to tell you though that using the IQFeed API is about the easiest and cleanest I have seen for some time." - Comment from Jim

"Thanks for all of your help. Great customer service deserves to be recognized which one the reasons I've been a customer of DTN for over 10 years!" - Comment from Stuart

"I'm very glad I switched to IQFeed. It's working perfectly with no lag, even during fast market conditions." - Comment from Andy via Email

"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

Author	Topic: Dropping support for older versions of IQFeed (3 messages, Page 1 of 1)
dhakme -DTN Evangelist- Posts: 150 Joined: Sep 17, 2004	Posted: Oct 19, 2010 07:19 AM Msg. 1 of 3 We are aware of emails sent out by Telvent DTN with the following message: "We are going to be upgrading our servers in the near future & the version of IQ you are using may not be compatible with the new server sets, and will no longer work." The emails don't give any details of the impending Server upgrades nor which versions of IQFeed will be compatible. I did reply to one of the emails but got no response. It would be very helpful if you could answer the following: 1) When are the Server upgrades planned? 2) Which versions of IQFeed will be compatible with the new servers? Thanks

All versions of IQFeed older than 4.5 should no longer be able to retrieve history once the changes are made. There is no definate cut-off date yet set for this change. There are still a couple of details outside the realm of IQFeed users that have to be addressed. Meanwhile we are pro-actively contacting customers who are still using older versions in an effort to get them to upgrade (or find out exactly why they wont).
