I'm reworking my software on a computer different from the one on which I normally run IQFeed. Both computers are running 5.1.1.3. The code for setting up IQFeed is the same in both my old software and the new software (if they are different, it is inadvertent and I am not aware of it).

In the new software, after specifying v. 5, I receive from IQFeed:
"S,CURRENT PROTOCOL,5.0,"

Then I issue the command:
"S,SELECT UPDATE FIELDS,Symbol,Last,Change,Total Volume,High,Low,Bid,Ask,Bid Size,Ask Size,Open Interest,Open,Close,Delay,Market Open,TickID,Last Size,Last TimeMS,Message Contents,Last Date\r\n"

The response (no errors have been reported) is:
"S,CURRENT UPDATE FIELDNAMES,Symbol,Most Recent Trade,Most Recent Trade Size,Most Recent Trade TimeMS,Most Recent Trade Market Center,Total Volume,Bid,Bid Size,Ask,Ask Size,Open,High,Low,Close,Message Contents,Most Recent Trade Conditions"

This is different from what I requested, from what the old software requests, and even from anything I have ever requested. I am struggling a bit to figure out what I have done to end up here. All the fields seem to be valid in 5.0. And when I start up my old software on the other computer and request a different set of fields, it works just fine.

Hello Eric,

The 4.9 and 5.x protocols have significant differences, this being one of them.
'If you look at this page it will tell you what fields are no longer relevant and what they have been replaced with in newer versions.

http://www.iqfeed.net/dev/api/docs/Level1UpdateSummaryMessage.cfm

Also, you will probably want to look at dynamic fieldsets as some changes there may be required to get the full list of fields you need to support your application.

A more general information link that discusses our protocol system.

http://www.iqfeed.net/dev/api/docs/IQFeedProtocols.cfm

I would start with these links though and if you have any questions, feel free to let us know.

Tim

Thanks for the response. Actually, I had gone over the material at the first two links several times before I started this thread. All the fields I requested are valid fields. The only thing I hadn't changed was the version (from 5.0 to 5.1), but I have done that and I still get the same results. I'm going to try uninstalling and reinstalling IQFeed next, unless you have any further suggestions.

Are you getting back the S,CURRENT PROTOCOL return after setting the protocol? You should get back that and a list of current fields.

Tim

Oh, I see now, you get two messages back on a protocol set, not one like on most things. That is the issue.

Tim

I reinstalled 5.1.1.3 Client (first) and 5.1.0.5 Developer (afterward). During the 5.1.0.5 download I got a message that the Client was the wrong version for the Developer. Can this have anything to do with the problem I'm having?

Tim,

Sorry, I was composing my last post when your responses came in, and I didn't see them.

I think part of the problem was that I sent the field request after receiving the version response without realizing that there was a default field response coming after the version response.

I do get a correct field response after the first, default one now, but I wasn't previously (I discovered the problem when I got an exception trying to access a field that wasn't there). I have moved my field request to a point after I get the default field response, and everything seems OK now.

Thanks for your help.

Ok, glad we got it. Let me know if anything else comes up.
