"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

IQFeed Developer Support » Missing Level 2 transactions... Or assumption is wrong! Jun 9, 2011 02:48 PM (Total replies: 0)

I am capturing level 2 data (TCP). I work under the assumption that the only way for a level 2 transactions to be canceled (ask or bid) is that a zero value be sent to the bid/bid size or the ask/ask size; or a replacement bid/bid size or ask/ask size.

At the end of the day I am left with maybe 10 to 15 unclosed u transactions on the ask side. Usually these exist on the ask side only, and they usually are less than 200 ask size quantity.

I am not checking reason code, condition code, bid info valid, or ask info valid. Are my assumptions correct so far?

The second part of the question when should I consider all transactions not accounted for as "no longer valid?". Should market close determine that... and should I be using the c<cr><lf> to trigger that in the 9200 TCP stream; or should I always expect a canceling "u" transaction?

IQFeed Developer Support » I would love to have all the c# examples you have... May 5, 2010 11:05 AM (Total replies: 3)

I have both 2010 and 2005 working on Sockets C#... I must assume that you have the c# examples.... The first one to work on would be connect to iqfeed... using sockets... 9300 admin... then 5009 and then 9100... Once you get 1 socket... the rest will follow... the only difference is you will need to understand that pieces of data will come to you... and you will have to ensure they are together... email me if i can be of further help... i will do my best...

IQFeed Developer Wish List » Increase the ability of your OCX to include history, etc... Mar 8, 2010 12:38 PM (Total replies: 2)

THE ABILITY TO SET THE FIELDS TO REDUCE PARSING... THE ABILITY TO GATHER TICK HISTORY.... ALL THE FUNCTIONALITY OF LOOKUP3.... THAT WOULD BE JUST WONDERFUL... IN THE INTERIM TIME... MAYBE SOMEONE CAN POST SOME MORE C# EXAMPLES... WHILE WAITING ON PRIORITIES FOR THIS ONE.... THANKS...

IQFeed Developer Wish List » Increase the ability of your OCX to include history, etc... Mar 7, 2010 04:04 PM (Total replies: 2)

The OCX is very nice for folks who are not professional programmers. It easily allows me to drop a control on a program and be up and running within 5 minutes..

The inclusion of history.. and other non supported areas outside of level I would be a great benefit for folks like me... I have spent two days trying to include Com (to have ticks) inside a c# program and I'm still missing the boat somewhere...

Thank you for any consideration given to this topic.

New to the board as well as new to the developer side... Please include me in on the c# examples... I would love as many that exist... It's not that I'm Stoop..... Id... but the more ways I see something... the easier it is... and the ole saying... Don't try to re-invent the wheel... cause it still works!!!!!
