IQFeed Developer Support » Consuming IQFeed APIs via C++ on Linux Yesterday @ 11:14 AM (Total replies: 2)

Apologies for the late reply; I've been on vacation.

I've been running IQFeed with Wine on Linux for years. Only once (back in 2015) have I had a significant problem, and Tim worked closely with me to solve it.


I don't have any information about the "Ping Failed" line. However, the rest of the log indicates that IQConnect started successfully but no app connected to the administration port (9300). IQConnect eventually shuts down if there are no connections to that port.

Before IQConnect shuts down, can you run one of the other IQFeed apps to see if it works properly? If so, the next place to look is in your app. If not, there are other possibilities; a firewall issue, for example.

One other thing occurs to me. You might be having trouble running IQConnect if Wine is in 64-bit mode. This happened to me in the past, and I worked around it, but I don't know if it's still an issue. To try the workaround, set the environment variable WINEARCH to "win32" before running IQConnect.


Install Wine. Then download the IQFeed client and install it (I used "wine iqfeed_client_5_2_5_0.exe"; just substitute the correct filename for the client that you downloaded).

You can start the IQFeed server (IQConnect) manually, or your application can start it automatically by executing the appropriate command with execl() or system(). The command will be something like "/usr/bin/wine /YOUR_HOME_DIRECTORY/.wine/drive_c/Program Files/DTN/IQFeed/iqconnect.exe -product YOUR_REGISTERED_PRODUCT_NAME -version YOUR_REGISTERED_PRODUCT_VERSION -login YOUR_LOGIN_ID -password YOUR_PASSWORD -autoconnect".

Once IQConnect has started your app can connect to the TCP ports and issue commands as described in the Developer Documentation.

Data and Content Support » Symbol Guide Changelist Is Stuck May 5, 2017 07:02 PM (Total replies: 1)

On http://iqfeed.net/symbolguide, the "U. S. STOCKS - ADDITIONS" page seems not to have been updated since April 21st.


Looks like it was nothing major -- just a few indexes.

Thanks!
Allen


I'll track down the symbols, then let you know. If they're just holdovers that I'm no longer using, there won't be any need to update the subscription.

Thanks!
Allen


I normally run an end-of-day tick history fetch for a few thousand symbols. Monday and today (Wednesday), about 95% of the fetch completed successfully, then it stopped because iqconnect returned "!ERROR! Unauthorized user ID." in response to the history request. Restarting iqconnect and re-running the fetch resolved the problem.

Tuesday there was no problem.

It might be coincidental, but the failure always occurred when fetching from the 148 servers and never when fetching from the 156 servers.

Running IQFeed version 5.2.5.0 under Wine on Linux.

Before I dive into debugging, did anything change on the 148 servers over the weekend that might account for this?

Thanks!
Allen

Data and Content Support » Old symbols appearing in symbol list additions May 10, 2016 01:13 PM (Total replies: 2)

Thanks!


Every day I grab a copy of the additions to the symbol guide from
http://iqfeed.net/symbolguide/display.cfm?eight=08011D32.cfm&six=0600036C&title=DTN%20-%20U.S.%20STOCKS%20-%20ADDITIONS

In today's file, I see a number of symbols that were retired after acquisitions. For example: AFFX, BDBD, CTCT, CYBX, DMND, DYAX (and there are quite a few more).

Assuming these companies haven't all been spun out again, it looks like there's a bug in the code that generates the symbol list.

IQFeed Developer Support » 5.2.0.5 Beta fails instantly under Wine Jan 19, 2016 07:05 PM (Total replies: 21)

Some of it's 4.9 and some is 5.1. No changes for 5.2 yet.

Looks like everything ran cleanly today. There were no disconnections, a large history fetch at the end of the day ran to completion, and the tick data appears to be correct.

My app connected without difficulty this morning and so far is running normally.

Looks good so far. We'll see how it does tomorrow when the markets are back in full operation.

Thanks for the fix!

Pardon; I can't tell if the attachment worked. Trying again.

There appears to be a call to an unimplemented function in msvcp110.dll. Crash information attached.

Looks like at least the "Additions" section of the Symbol Guide on iqfeed.net is stalled again -- stuck at 05/29/2015.

IQFeed Developer Support » 5.1.2.5 iqconnect failing under Wine Apr 25, 2015 11:06 AM (Total replies: 4)

I'm still seeing crashes with 5.1.2.5. Switching from the 64-bit Wine server to the 32-bit server reduces the number of crashes, but doesn't eliminate them. 5.1.1.3 works without crashing.

I've been working with Tim and Steve to narrow down the cause, but so far they haven't been able to reproduce the problem on their system with their tests. I'm extracting code from my app to create a minimal sample program that triggers the crashes, but that's going very slowly; testing takes a lot of time when we don't know exactly what prompts a crash.

It's also possible that the version of Wine I'm running doesn't match the version that Tim and Steve are running. We've coordinated to bring their release up to date, but it's possible that Wine built for Fedora (which I'm using) differs from Wine built for OpenSuSe (which they're using) even if the version numbers are the same. Checking this is also on the to-do list.

Following up: This appears to be caused by history requests, but not immediately after issuing them.
