I'm seeing some messages arriving with odd data in the first field.


In some cases the "Q" is simply missing, for example:

,@NQM5,10,1548.00,-2.5,-0.001612383,6796,5,1552.50,1547.50,1548.00,1548.50,10,180,183,,5.,09:05t,319595,1550.00,1550.50,0.5,,1549.00,,,,,,,06/06/2005,,1548.00,06/17/2005,,,-2.5,0,,,0.5,0.5,-2.,1,0.003229974,,12,2,10,,,1550.00,0,0,0,920,,,,,
06,05,05,453,NQ

In other cases, the Q is prepended with the character 0x0D.

Are you seeing this issue with one of the IQFeed apps, or your own? How many, and which symbols were you watching at the time? How often are you seeing this issue?

Any other information you can give me to re-recreate the issue would be great. Thanks!

My own app. Just implemented the beta API this weekend.

Watching a total of 59 tickers. I'll post a list later if you need them. As best I can tell this happened between 9 & 9:30 EST, but I'll know more when I anyalyze my log file after the mkt close today.

If you have a test app you can modify, I'd suggest putting in a trap to catch any instances where the field length is not equal to 1. I also saw this on a time message:

,20050606 09:14

Looking at my log I find the missing Q for @YMM5, DIA, @ESM5, @NQM5, CMCSA in pre mkt this morning. I don't like to disturb my app during regular trading hours.

Hope you don't mind my ticker list as a code snippet.

Thanks for the info. I'll try to recreate this here, by looking at IQFeed's log file. If you would like to do this too, that would be great.

The registry settings for logging are found in the registry in HKEY_CURRENT_USER\Software\DTN \IQFeed\Startup. Use LogPath to set the path to the log file, and set LogLevel to 1. The log file is named IQConnectLog.txt, and will be placed in the path that you have set.

I'll try setting the log level to 1. Please check your PM, I'm sending some more info there.

FYI - still working on this.
