"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

Using the new beta DLL. TCP/IP history requests for yesterday's minutebars. Done this morning around 0730h for top 900 naz symbols. Roughly 1/3 returned "!NONE!"+blankline+"!ENDMSG!".

Today, there were no "!NONE!" results to my history requests. I tried both old and new connectors.

This evening, around 9:30 PST, history requests for top 900 Nasdaq symbols returned 450 as !NONE!.

I used the new beta connector.

Is there something significant about the time of day that affects this? Each request was asking for 2 days of 1 minutebar data to ensure getting today's tradng data.

I reran the job 1 hour later and things worked fine.

How many days of minute data did you request when you saw the problem? The !NONE! message is sent when history data was not received. Thanks!

Sorry, I see that you are requesting 2 days of data. How long does your process take to run? Thanks!

I usually ignore it while it is running, so the execution time is a guess. About 30 - 40 min.

Here's a zip file of the request commands and responses. The "CTL,.." stuff is my own control info. 64.69.78.24\tmp\h050606a.zip

Thanks for looking at this.

Today, at 0830pm - 0900pm PST, a minutebar history pull worked fine. It was asking for one day and got today's data (050608).

At 0930pm PST I reran the job, asking for 2 days of data and most of the symbols failed with a !NONE!. I got the same results manually from the C++ History Socket demo. I.e, asking for 2 days got nothing, but asking for 3 days got 050607 only, missing the 050608 for what is by now yesterday and of course none for 050609 which hasn't happened yet.

At 1045pm PST I reran the job again and it worked fine. It asks for 2 days and gets 050608 as expected.

So, all this looks like interference from some end-of-day processing. If you know what times to avoid, I'll follow your lead. Otherwise, trial and error will rule.
