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.

The !NONE! message is sent when history data was not received. Thanks! Natalie Natalie Hannan DTN Market Access, LLC.

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.

kdresser -Interested User- Posts: 71 Joined: Nov 25, 2004	Posted: Jun 9, 2005 12:49 AM Msg. 8 of 8 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. ###
