"I use IQ Feed, Great stuff as far as data analysis information, storage and retrieval is concerned." - Comment from Public Forum

"With HUGE volume on AAPL and RIMM for 2 days, everyone in a trading room was whining about freezes, crashes and lag with *******, RealTick, TS and Cyber. InvestorRT with IQFeed was rock solid. I mean SOLID!" - Comment from Public IRC Chat

"I have been using IQFeed now for a few years in MultiCharts and I have zero complaints. Very, very rare to have any data hiccups or anything at all go wrong." - Comment from Public Forum

"DTN feed was the only feed that consistently matched Bloomberg feed for BID/ASK data verification work these past years......DTN feed is a must for my supply & demand based trading using Cumulative Delta" - Comment from Public Forum Post

"It’s so nice to be working with real professionals!" - Comment from Len

"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

"Can I get another account from you? I am tired of ******* going down so often" - Comment from George

"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

"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

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).
