Several times today and yesterday, I've gotten a "not found", reissued the request, and gotten a valid response. For example, just now:

HD,SUNW,500;
!ERROR! !NONE!
HD,SUNW,500;
!ERROR! !NONE!
HD,SUNW,500;
!ERROR! !NONE!
HD,SUNW,500;
<data received as normal>

We havent (yet) recieved any other reports like this.

You mentioned that this has been the last 2 days. Was yesterday the first time you saw this?

Initially this seems as though you might be getting an extra character in your request buffer

Can you post an IQConnect Log for when this happens?

Last night around midnight eastern. I thought it was simply the midnight maintenance causing the problem, but when I saw it again today during trading hours, I got suspicious.

Is the log available on my disk now, or do I have to turn something on?

I wouldn't think it's an extra character--it's the same TCP/IP code which has worked perfectly for the last 6+ months. :-)

I appreciate this as it would initially be my reaction as well...but on the other side of the coin, our history servers handle hundreds of thousands of requests a day and this is the only report we have heard as of yet. This seems just as unlikely.

Perhaps this is simply the "tip of the iceburg" and the issue simply hasnt developed enough to gererate a lot of support tickets on it but right now, there isnt enough evidence to make that jump.



IQConnect logging can be turned on via the registry. Check your documentation section titled Logging or registry settings.

Indeed! Given the wide variety in customers' code, looking there first is a logical choice, so I'm with you.

I'll turn on logging and hope (sort of) that it happens again.

Well, it just happened again today. My log is some 180MB, so I've just included the relevant parts. If you need the whole log, I can zip it up and put it somewhere.

Hi Steve,

Just checking to make sure you got my last post. Do you want a copy of the log? Do you have enough?

Thanks!

We are looking into this. Have you seen it happen with other types of requests? both examples you have posted show it happening with a daily request.

Can you tell us a little more about the type of activity you are using the feed for at the times it happens?

How many symbols are you watching?
How often does your app make a History request?
Is it only Daily Requests?

any extra information you can provide will help figure out what is causing the issue.

I've only seen daily, but that may have more to do with the frequency of my requests than anything else. I rarely request history for sub-daily data (probably 50:1 daily to sub-daily).

You posted while I was editing. Just wanna make sure you noticed the extra questions.

In general, this seems to happen more frequently in the last hour of trading.

The problem occurs as I'm looking at opportunities or going through my portfolio. I'm retrieving the daily data and charting it to determine if I need to make adjustments.


Probably between 75 and 100, including the symbol for which I requested history. My app both watches the symbol and requests the history more or less simultaneously.


I have a caching ability to prevent making lots of history requests, but it will require at least 1 bar to get an overlapped bar to look for splits/etc.

In general though, it requests history as frequently as I click. (Perhaps every 5-10 seconds if the chart isn't interesting, every minute or 2 if it is)


So far, but really, my decisions are based mostly on the daily chart. Ocasionally, I'll get the higher frequency data, but, as I said in my other post, it's probably 50:1 daily to sub-daily requests.


- The issue does seem more prevalent in the last hour of trading.
- Sometimes a single re-request of the daily history will be successful, sometimes it takes 4-5.
- I see similar activity if I'm requesting historical data during midnight maintenance (known good symbols come back as unknown)
- There doesn't seem to be any particular pattern to the symbols which have a problem (CSCO, IOTN, various options)
- It happens pretty infrequently, but is persistent when it does (i.e. several queries are required to get data, and often other symbol failures occur at the same time)

I hope that helps!

Please send me a Private Message (or an email to the developer support email) with your username you log into the feed with and we will look into it on the server side.

Hi Steve, I presume you got my email to the developer email list--if not, let me know, and I'll resend.

This just happened again just a minute ago:
HD,GRMN,500;
!ERROR! !NONE!

Our server team has looked into this and we can confirm this is an issue with the servers. There is some "wierd stuff" happening that we haven't been able to track down yet. Part of the wierdness is that we still haven't recieved any other complaints on the issue.

During the evenings when I do my downloads, I'll experience the same thing. It happens only sometimes. I download 1 minute bars and daily stuff simultaneously, about 10 or 15 symbols at a time, with a total of about 2900 symbols. The 1 minute bars seem to come down ok, but I'll get the ERROR NONE on groups of daily bars. When I run the daily bars by themselves, all seem to come down fine.

On a possibly related note, many moons ago, I also related an issue where if I download too many too fast and run the download up to 100% of my bandwidth, some symbol downloads won't complete. I don't know if this is related or not.

I'm getting TONS of these "Error None" announcements today. At least 6 in the last few minutes on different symbols (ranging from options to equities)

Quite a few today as well. Several at 2pm eastern, and a few near market close.

This problem seems to be getting worse?

We believe we have identified the source of this problem, unfortunately it cannot be resolved with a "quick fix". As a result we will continue to monitor the issue and adjust its priority accordingly.

Just FYI, this is still occurring. Today, while the market was open:

HD,VG,500;
!ERROR! Invalid symbol.

HD,VG,500;
!ERROR! Invalid symbol.

HD,VG,500;
!ERROR! Invalid symbol.

HD,GE,3;
!ERROR! Invalid symbol.

HD,VG,500;
!ERROR! Invalid symbol.

The next try gave me VG.

Will this be fixed in the server release next weekend? I just had to request AIG 8 times.

Unfortunately this will not be resolved with the server release. I have brought this back to the attention of the server team.
