"I am enjoying the feed very much - so superior to the broker provided feed I was previously using." - Comment from George
"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
"There is no doubt that IQFeed is the best data provider. I am very satisfied with your services. And IQFeed is the only one that I would recommend to my friends. Now, most of them are using your product in China." - Comment from Zhezhe
"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
"Interactive Brokers tick data was inconsistent, so I have switched to using DTN exclusively. It is great to no longer have to worry about my datafeed all day long." - Comment from Philippe
"I've been using IQFeed 4 in a multi-threaded situation for the last week or two on 2600 symbols or so with 100 simultaneous daily charts, and I have had 100% responsiveness." - Comment from Scott
"Very impressed with the quality of your feed - ******* is a real donkey in comparison." - Comment from A.C. via Email
"Thank you so much - awesome feed, awesome service!" - Comment from Greg via Email
"Everything is working great ! Very impressive client. The news refreshes better and is more pertinent than the ******* feed I paid $ 100/month for. I Also like the charts a lot." - Comment from Leon
"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues. I was on ******* for a few years before I made the switch over early this year, and wish I had done it a long time ago." - Comment from Ken

Can someone please tell me what the difference is between: - S,CURRENT UPDATE FIELDNAMES
- S,UPDATE FIELDNAMES
When I specify "S,CURRENT PROTOCOL,6.0" the response includes both of these, one after the other, and the first has less fields listed than the second. I can see that "CURRENT UPDATE FIELDNAMES" maps to a [P] summary message, yet "UPDATE FIELDNAMES" doesn't seem to map to an [F] fundamental message. Does this dual output have anything to do with the fact that I specified "trade-only watch?" Perhaps I'm misunderstanding.

<UPDATE FIELDNAMES> reports the full list of fieldnames that are potentially available from IQFeed in response to watch commands (currently about 65 fields). <CURRENT UPDATE FIELDNAMES> reports those fields that IQFeed currently includes in your watch messages. By default this includes only 16 fields out of the ~65 total fields that are potentially available. The process for selecting which data fields IQFeed includes in your watch messages is described here: http://www.iqfeed.net/dev/api/docs/DynamicFieldsets.cfm Note: I am not a DTN employee; my post reflects my personal opinion and not necessarily DTN's

Thank you, altmany. Between your explanation and looking at source examples, I understand.
