"I am a hedge fund manager here. It’s funny, I have a Bloomberg terminal and a Bridge feed, but I still like having my DTN feed!" - Comment from Feras
"I am enjoying the feed very much - so superior to the broker provided feed I was previously using." - Comment from George
"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've been using Neoticker RT with IQFeed for two months, and I'm very happy with both of the products (I've had IQFeed for two years with very few complaints). The service from both companies is exceptional." - Comment from Public Forum
"I've been using IQFeed 4 in a multi-threaded situation for the last week or two on 2600 symbols or so with 100 simultaneous daily charts, and I have had 100% responsiveness." - Comment from Scott
"The service is great, I see a noticeable improvement in my volume profiles over [broker]'s data feed" - Comment from Larry
"I started a trial a few weeks back before the market went wild. DTN.IQ didn’t miss anything and beat my other provider. I decided to stay with you because of the great service through all the volatility." - Comment from Mike
"You are much better than lawyers or the phone company because you answer the phone when I call! I just love your customer service." - Comment from Isreal
"This is an excellent value, the system is generous (allowing for 500 stocks) and stable (and really is tick-by-tick), and the support is fantastic." - Comment from Shirin via Email
"IQ feed works very well, does not have all of the normal interruptions I have grown used to on *******" - Comment from Mark

I have subscribed IQFeed for nearly 3 months, the big connection issues is here:

IQFeed Data connection did not works in China and the connection drop repeatted and IQFeed frequently automatically logout with an error message " Sorry, your Product and/or Service for the attempted login are incorrect. If you have recently changed products you may also need to change your type of service. Please contact DTN customer support for assistance. (1)" Then IQFeed will automatically close in about 15 seconds. After that, IQfeed process is dead, and automatically reconnect will failed. So i must terminate the previous IQfeed process and restart it. please refer to the attached screenshot.


I tried and tested on the two main ISP in China, China Telecom and China Unicom. China Telecom seems a little more stable than China Unicom. But the result is same. I also tried on my two worksations , there are same error result.

So i think there is a connection problem on IQFeed connection from Shanghai, China to US server. Then I start to run IQfeed on VPN connection, it became more stable than direct conneciton. but there will be some connection drop too. As you guys may know China Great Firewall aways disrupt VPN connection, that means VPN connection is not stable. But at least, there are less drop when IQFeed running on VPN connection.

I have report this issue through live chat, but it looks there are few users in China so there is no good solution.

If any guys here have such similar problems and know any solution please let me know.

Thanks
Aaron

Hi Aaron, the "sorry, your product and/or service for the attempted login are incorrect" is not typically associated with a bad connection. While a connection problem can trigger it, more often it means that there is a problem communicating with an application/software, i.e. either the software is unsupported or there is a process hangup between the two products.

It's certainly possible that you have an internet connectivity problem that is outside the scope of IQFeed support. However, you may also want to reach out to us again in chat so that we can get more details from you, to determine if something else is happening here.
