"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim

"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues. I was on ******* for a few years before I made the switch over early this year, and wish I had done it a long time ago." - Comment from Ken
"Everything is working great ! Very impressive client. The news refreshes better and is more pertinent than the ******* feed I paid $ 100/month for. I Also like the charts a lot." - Comment from Leon

Two brief disconnections (of about 10 seconds) over the last couple days. But at 03:13:36 (ET) this morning it disconnected and hasn't been able to reconnect; attempted reconnections approaching 7000 at 05:10.

Now I'm getting P records with no data. Do you do maintenance on Saturday mornings, perhaps? That might explain today's problems.

Here we go again: About a half hour after startup, we got a disconnect.

It happened again this morning: Disconnect reported at 10:24:41; Seconds Since Last Update is currently 99685; Attempted Reconnections is somewhat lower at 98300; Reconnections is 1.

We're still good: 2 Reconnections during the night on 16 Attempted Reconnections; total of 14 seconds lost.

Thanks, Tim. I received the link and am now running on 5.1.3.199. Time will tell if it resolves the reconnection issue; it didn't solve the previously reported problem of not connecting on the first attempt, which requies me to stop and restart my software.
Eric

A Disconnect occurred again this morning at 2:03:22 (Eastern). It's now 6:30 and Reconnections is 0, and Attempted Reconnections is at around 15900 and still climbing. Our Internet connection is fine, as you can see. I have logging turned on and will send the file (or part of it) if you wish. I will just leave things as they are for now until I hear from you.

Tim,
Things have stabilized now. We have been up for almost three and a half hours. Reconnects and Attempts have not changed since my last post.
Eric

Tim,
I’m using 5.1.3.1. Sorry, I didn’t think to check for reconnections before restarting. But since the restart about an hour and a half ago we have 2 reconnections and 64 attempted reconnections. Seems like quite a lot of attempts.
Eric

IQFeed Developer Support » Disconnects Aug 21, 2015 08:00 AM (Total replies: 22)

Disconnected again. Reconnected automatically, but took 53 seconds.

We have had several disconnects this morning, after one of which IQFeed Connection Manager did not reconnect. After a couple of tries we were able to get reconnected, but then got another disconnect followed by the error message "Socket Error: 10054 (WSAECONNRESET)."

Steve,
Thanks for the response. The firewall has been open for IqConnect for several years on this computer. Otherwise I would not be able to get data after the second or third try--or for the last several years. Something else is going on that is relatively new. As I said, it is not crippling, but is a nuisance.

Patrick,

Thanks for the information. My network is hard-wired, and I am trying to connect with only one computer at a time; so that doesn't seem to be the solution for me.

I hadn't noticed the new version, so just installed it; Still getting the same result. Guess I'll have to wait for DTN to look at the logs. It's a minor nuisance, but fortunately doesn't interfere with operation here.

Best wishes,
Eric

I had been hoping to see something further about this, since I have been having the problem too. In my case, it fails frequently on the first attempt to start IqConnect, but succeeds on the second attempt. Sometimes I can get it to work when it appears to fail by clicking on Connect, but most times this doesn't work.

I have had another problem with the 5.1.2.5 hanging when I disconnect, preventing me from subsequently starting up. In these cases I must kill the IqConnect process in Task Manager, but this is not usually the problem.

Here's a partial log when it fails:

Steve,

Thanks for taking the time to explain the cause of this message. Understanding what's going on in the code behind sometimes-cryptic error messages is an immense help.

Best to you and Tim this holiday season.

Tim,

Put this one on hold for a bit; I may have found the source of the problem.

When I ran my software on a faster computer this morning, it appeared that some of the lookup data were getting processed out of order. Since I put all data in a queue as soon as it comes in, this seemed impossible. I have since traced the problem to a too-small lookup buffer; data were being truncated, not rearranged. Because we have upgraded our LAN and Internet speed lately, data are coming in and filling the buffer more quickly. I doubled the size of the buffer, and the problem disappeared. My suspicion is that this was also causing the problem connecting to the history socket, although it may take a day or so to make sure it too has gone away.
Eric

Tim,

I added code to track my requests and IQFeed responses, but for a while I thought it was going to be a variant of the Heisenberg principle: observation changes the behavior. But on a restart this afternoon I got several examples (attached). One is an expired or expiring contract, but two are high-volume contracts. I'll appreciate hearing if there's something I am doing wrong. As I mentioned earlier, however, the majority of the requests succeed without this error. (Note that I have added a horizontal rule to separate the contracts, and in the successful responses an ellipsis [. . .] to shorten the file.)
Eric

IQFeed Developer Support » Could not connect to History socket. Dec 18, 2014 10:29 AM (Total replies: 8)

Tim,

Since I had never seen this error before, I don't have any code to log it to disk. I'll put something in today, but it may be tomorrow before I can get you results.

It happened again a few minutes ago on another startup. It occurred to me that it might be a connection problem, but IQFeed didn't report a disconnect, and the Connection Manager showed no Reconnections or Attempted Reconnections.

Thanks for the quick response.
Eric
