"I used to have *******, but they are way more money for the same thing. I have had no probs with data from DTN since switching over." - Comment from Public Forum Post
"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
"I'm very glad I switched to IQFeed. It's working perfectly with no lag, even during fast market conditions." - Comment from Andy via Email

"I just wanted to tell you what a fine job you have been doing. While *******, from what I hear, has been down and out, off and on, IQ feed has held like a champ this week." - Comment from Shirin

"I am keeping IQFeed, much better reliabilty than *******. I may refer a few other people in the office to switch as well." - Comment from Don
"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim
"As a past ******* customer(and not a happy one), IQ Feed by DTN is a much better and cheaper product with great customer support. I have had no problems at all since switching over." - Comment from Public Forum

Odd.

I'm trying to retrieve historical 1-minute bar data for SPX.XO, from 2007 - present. For example, using the following request:

HIT,SPX.XO,60,20160101 093000,,,093000,160000,1,SPX.XO_HISTORY_9b1j30oylux517pwdzq1,,s

...and the odd part is that I'm getting an early !ENDMSG! after only 2500 bars retrieved (the value of DatapointsPerSend; if I raise DatapointsPerSend to 5000, I get 5000 bars before the !ENDMSG!).

I'm *fairly sure* I've succeeded before in pulling much more than DatapointsPerSend before getting !ENDMSG!... so I wanted to check if anything changed on the IQFEED end?

same thing happening with HID, for example:

HID,SPX.XO,60,5200,,070000,170000,1,SPX.XO_HISTORY_mvfc3essif69izxqh4k9,,s

returns on 2500 1-minute bars, instead of all available.

It's not symbol specific, I see the same truncation with 'SPY' and 'AAPL'.

If I set the DataPointsPerSend to 5797440 (asking server to queue all/approximately 11 years worth of 1 minute bars before sending it all down the socket), then I got 6369 lines of AAPL history 1-minute bars, covering only 2007-04-27 to 2007-05-21. This was the query:

HID,AAPL,60,5200,,070000,170000,1,AAPL_HISTORY_cwzp8cavvynj49tywc0y,5797440,s

Similarly for SPY I got only 10618 bars, covering 2007-04-23 to 2007-05-31.

Perhaps the database is down for maintenance? I should expect it to be available all weekend, no?

Thanks.

This is not an IQFEED issue but rather something to do with my code, since I can checkout an earlier version of my code and the earlier code retreives symbols far beyond the 2500; it works correctly.

Still puzzling over what the problem could be, so suggestions welcome.

Yep, Nevermind. This was all user error on my part.
