"DTN has never given me problems. It is incredibly stable. In fact I've occasionally lost the data feed from Interactive Brokers, but still been able to trade because I'm getting good data from DTN." - Comment from Leighton
"Thank you so much - awesome feed, awesome service!" - Comment from Greg via Email
"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 have been using IQFeed now for a few years in MultiCharts and I have zero complaints. Very, very rare to have any data hiccups or anything at all go wrong." - Comment from Public Forum
"IQFeed version 4 is a real screamer compared to anything else I have seen." - Comment from Tom
"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

Hi,

I noticed "Open Interest" is missing from the 5.2 update/summary message docs at:

http://www.iqfeed.net/dev/api/docs/Level1UpdateSummaryMessage.cfm

but I didn't see it mentioned in the upgrade guide. Is this field part of the 5.2 protocol?

Hello Brad,

I am sorry, I must have accidentally deleted the field when I was updating the documentation in a recent release. I have added it back into the documentation. Thanks for posting and letting me know.

No problem

Please also note that while you have removed the ordinal column, the descriptions still reference fields by number, which is likely to be confusing for developers that haven't seen the 5.1 docs.

Good observation, I'll take care of that this morning as well.

Thanks for the feedback!

Hi Tim,

Fields 10, 11 and 12 of regional messages are indicated to be type String on the following page:

http://www.iqfeed.net/dev/api/docs/RegionalMessageFormat.cfm

As far as I can tell, they are always integer fields. Is the documentation wrong? Or could these potentially not contain price/mkt index codes?

I certainly cannot think of any place those would be a non-int. I have updated the docs accordingly. Thanks for the heads up.

Tim
