"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob

Hi, I'm a new IQ Feed API user.

I just built the API in VB, and started up the Market Summary Socket. When I tried to Request End of Day, I get a response of "No file available".

I am using: Request: EDS,1,1,20200720,1.

Any idea what is wrong?

Also, is there a timeline of when the market summaries are available each day (except 5MS of course)?

Thanks!

Reposting response from Support to help other noobies:

The EDS command uses the exchange group ID, not the exchange ID. If I send the command SLM to the API, you can see the distinction:

SLM
1,NGM,Nasdaq Global Market,5,NASDAQ,
2,NCM,National Capital Market,5,NASDAQ,
3,OTC,Nasdaq other OTC,5,NASDAQ,
4,OTCBB,Nasdaq OTC Bulletin Board,5,NASDAQ,
5,NASDAQ,Nasdaq,5,NASDAQ,

NGM is exchange ID #1, but it belongs to exchange group #5 (it is part of NASDAQ). EDS accepts the latter. There is no group #1, which is why your EDS,1,1 returns "no file available."

EDS doesn't use the exhange ID (the first number), it uses the group ID (second from the last). NGM belongs to exchange group ID #5, NASDAQ. So if you want that exchange, you would send EDS,1,5,20200724. Please note this will include all the NASDAQ exchanges, not just NGM.

EDS files are compiled promptly after market close. I don't have an exact schedule of how long it takes, but a few minutes should be enough to wait.

Let me know if this does not answer your questions!

Sincerely,
Gary Stephen
