"Previously I was using *******. IQFeed is WAY more economical, and for my charting needs is just as good, if not better." - Comment from Public Forum Post

"I've never had DTN go out on me since switching. ******* would go down a couple times every month when I was using them." - Comment from Bryce in AL.

"I just wanted to tell you what a fine job you have been doing. While *******, from what I hear, has been down and out, off and on, IQ feed has held like a champ this week." - Comment from Shirin

"There is no doubt that IQFeed is the best data provider. I am very satisfied with your services. And IQFeed is the only one that I would recommend to my friends. Now, most of them are using your product in China." - Comment from Zhezhe

"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

"Excellent datafeed !!!" - Comment from Arely

"You have an excellent product !!!!!!" - Comment from Arely

"Awesome response, as usual. It is a sincere and refreshing pleasure to do business with DTN, compared to your competition." - Comment from Ryan

"I'm satisfied with IQFeed. It's the most reliable and fastest quote feed I have ever used. Although I'm a resident in China, it's still very fast!" - Comment from Xiaofei

"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

Author	Topic: Connection error when using IQFeed in Linux Wine (4 messages, Page 1 of 1)
phaser -Interested User- Posts: 3 Joined: Apr 2, 2019	Posted: Apr 2, 2019 03:01 AM Msg. 1 of 4 I've been reading about how IQFeed can run reliably under Wine-Stable, so I've been testing it out for the past 2 days. Below is a description of the issue I'm facing, any help would be highly appreciated! ISSUE: - After installing IQClient under Wine, I opened IQLinkLauncher.exe, entered my username and password on the pop-up box. - I ran a simple Python script to download historical data but it said IQFeed is not connected. - I then ran Diagnostic.exe. Out of 10 times I click on the 'Test' button, I only succeeded once or twice in getting data but in those rare occasions, after the initial batch of data is received, the connection fails again. - Thinking of debugging the issue, I clicked on the 'Connectivity' tab, which says: ======= login.interquote.com Trace route to 66.112.148.213 Hop Min RTT Avg RTT Max RTT IP Could not get a valid ICMP handle ======= - To confirm that there is nothing wrong with my internet, I re-ran the above using the IQLinkLauncher installed on my host Win8.1 and everything was fine. The connection was very stable and never needed a re-login. I really have no idea what is wrong. My setup: (1) Debian Jessie 64-bit Virtualbox VM running on Win 8.1 host Steps I took for Debian VM: (1) Installed Wine (NOT: Wine-Development) based on the instructions here: https://wiki.debian.org/Wine. I started from Step 1, then step 2: Standard installation (2) Ran 'winecfg' (3) Installed iqfeed_client_6_0_0_5.exe (in the process, it installed vcredist_x86_2012u4) in Wine Edited by phaser on Apr 2, 2019 at 03:02 AM Edited by phaser on Apr 2, 2019 at 05:08 AM Edited by phaser on Apr 2, 2019 at 05:08 AM

Try the latest which is 6.0.1.1, I believe. Try building your VM with Stretch. Although describing a container build, the same wine configuration can be used in a regular VM (you may need to copy and paste the link rather than clicking on it): http://blog.raymond.burkholder.net/index.php?/archives/950-Gui-using-Wine,-X2Go,-LXDE-in-a-simple-LXC-container.html There might be an issue with the news service. If so, see the following for a fix: http://blog.raymond.burkholder.net/index.php?/archives/747-DTNIQFeed-Gecko-Problem-in-Wine-from-WineHQ.html To get IQConnect 'locked in', I run the SnapQuote application twice. The first time starts IQConnect, and the second time actually makes a connection after choosing a symbol. I then close the first SnapQuote application.

To connect to the IQFeed API, you only need to launch IQConnect.exe. The "IQLink" tools in the IQFeed client software are for manually starting DDE, and they aren't necessary in modern versions of Excel. They're only included for legacy reasons.
