"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

Thank you, very much. It was the filter to log the records with only 't', 'a' and 'b' codes. All works now.

Have a nice day,
Andrew

No, no, I'm not using breakpoints. I will update the client to the latest version and check again and let you know.

Hi!

I'm switching application from 4.9 to the latest protocol (it is late, I know) and can't recognise the correct way to determine which filds were updated in "Q" message, trades, asks or bids. Previously it worked well with depricated field "Last Trade Time" but now I have to use "Message Contents" field.

The problem is that I'm getting only "a" or "b" or "ab" messages and no other types.

Updated fields:
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.
**********
QQQ, I put below two messages where Total volume is different (i.e. the trade occured), but both have "ba" status.

Thank you,

Then we have the problem....

IQFeed Developer Support » Lookup of expired symbols May 9, 2013 09:03 AM (Total replies: 2)

Hi!

The query to lookup for expired symbol returns NO_DATA. Tested this using SymbolLookupSocket_VC.exe, IQFeed 4.6.1.0 and symbol @ESM12.

Can it be fixed somehow?

Andrew

IQFeed Developer Support » ISymbolLookup Jan 8, 2007 03:09 PM (Total replies: 3)

Thank you for your answer. I'm not often visiting this forum unfortunately and forum search is limited to 90 days only :)

I hope in the next version of the API it will be corrected.

IQFeed Developer Support » ISymbolLookup Jan 8, 2007 11:45 AM (Total replies: 3)

The LookupSymbol method returns found symbols in <symbol>space<description> format.

We need to extract from each found string symbol and its description as separated strings.

For symbol like MSFT MICROSOFT CORP we can simply subsrtact symbol as chars left of first space.

For symbol like MQF AO MSFT JAN 2007 C 17.0 we have to substract all left of the second space.

So, there is no one algorythm for extraction symbol from the result string.

Do you have any work-around?

Hello!

I have found messed data for few symbol. It is eturned just one daily bar.
Symbols:
GCG5
FVH5
FVM5
EUH5

It is tested with our software and history.exe from SDK. We are using 2.3.0.1.

Best regards,
Andrew Nazarov

IQFeed Developer Support » Wrong data for LHZ4 Dec 8, 2004 03:36 PM (Total replies: 6)

DTN Client 2.3.0.1, all software including SDK test applications have the same.

Andrew

IQFeed Developer Support » Wrong data for LHZ4 Nov 14, 2004 08:43 AM (Total replies: 6)

My cusomer reported that the data for this symbol is bad time-to-time. The testing at our side showed the same. For example, the 1 minute data 8 Now 12-00 and 12-01 PM (EST). Open record is 33689.85600, high record is 1812856.83300. The data 10 Nov 11-15,11-18 and 11-20 (AM) are wrong.

The supports says that there is no problem at the server data base, but error shows two possible reason: or database error, or IQFeed API error. I'm ready to give you additional information if you need.

Best regards,
Andrew Nazarov

As far as I know it is not possible.

IQFeed Developer Support » Detecting if IQConnect is running May 11, 2004 12:28 PM (Total replies: 4)

The only problem which you should expect then, when the 1st application will be closed, it will close IQConnect too because it doesn't know about your 2nd application.
