"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum
"I just wanted to say how happy I am with your service. I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email
"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

"DTN feed was the only feed that consistently matched Bloomberg feed for BID/ASK data verification work these past years......DTN feed is a must for my supply & demand based trading using Cumulative Delta" - Comment from Public Forum Post

IQFeed Developer Support » IQLink/DDE problem Jun 11, 2018 08:43 AM (Total replies: 18)

It seems to have happened :)

I sent 'w@ADN18' to port 5009, and i received a fundamental message about this symbol.

I think, the problem is solved, thank you! :)

Tim, good morning!

I downloaded and installed the latest version of the API (instead v5.1.1.3).

Which port do i need to connect with telnet, that would get data on the symbol expiration time?

I can't reply to your letter, in response to sending the letter I received:

SMTP error from remote mail server after initial connection:
host []: 554 client's country is banned

Tim, good morning!

Can you help me compose a fundamental message to get the symbol expiration time? I can not understand from the help page how to compose it. For example, symbol @ADN18.
And what interfaces do I need to use, ILevelOneGeneral2 will be sufficient?

Good morning Tim!

Yes, we have development account, and I see the page 'Fundamental Message Format'.

Ok, thank you! I'l try this way.

Can I get the exact expiry date by the symbol from other channel (TCP\COM)?

IQFeed Developer Support » IQLink/DDE problem Jun 6, 2018 02:43 AM (Total replies: 18)

Hi all!

I'm trying to get data over DDE channel from IQLink. C++\WinAPI.

::DdeConnect passes without errors, but ::DdeClientTransaction returns an error 0x4009 (DMLERR_NOTPROCESSED).

HSZ hszField = ::DdeCreateStringHandle(dwIDInst, "Exp Date", CP_WINANSI);

DWORD nDDERes = 0;
HDDEDATA hData = ::DdeClientTransaction(NULL, 0, hConv, hszField, CF_TEXT, XTYP_REQUEST, 1500, &nDDERes);
// hData is null
// DdeGetLastError returns DMLERR_NOTPROCESSED

What am I doing wrong?
IQFeed v5.1.1.3
