"I was on the phone with a friend who uses CQG and right after the Fed announcement, CQG was as much as 30 seconds behind DTN.IQ. Some quotes were off by as much as 15-18 cents. Your feed never missed a beat." - Comment from Roger
"Thank God for your Data Feed as the only Zippers I see are on my pants (LOL), and no more 200 pip spikes to mess up charts." - Comment from Spiro via Email
"Previously I was using *******. IQFeed is WAY more economical, and for my charting needs is just as good, if not better." - Comment from Public Forum Post
"Very impressed with the quality of your feed - ******* is a real donkey in comparison." - Comment from A.C. via Email
"I was with ******* for 4 years at $230 a month, this is a huge savings for me, GOD BLESS YOU PEOPLE," - Comment from T.S. via Email
"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
"The service is great, I see a noticeable improvement in my volume profiles over [broker]'s data feed" - Comment from Larry
"If someone needs the best quality data and backfill beyond what their broker provides at a rate that is the best in the industry, I highly recommend IQFeed." - Comment from Josh via Public Forum
"This beats the pants off CQG, I am definitely switching to the ProphetX 3.0!" - Comment from Stephen
"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

Trying to get the S&P500 stock components with below logic:
history(q,char(stocks(n)),{'01/01/2011','08/23/2013'},'Daily');
where stocks is a cell array with all 500 components.
put this in a loop, with 4 sec delay, and the history command will stop returning the total amount of days for a specific symbol.
For example:
Symbol: EXPD, Nr.of days collected:665
Symbol: EXPE, Nr.of days collected:665
Symbol: F, Nr.of days collected:1
Symbol: CVS, Nr.of days collected:665
Symbol: CVX, Nr.of days collected:1
Symbol: CBE, Nr.of days collected:665
Symbol: CBG, Nr.of days collected:14
each time the program will reach these particular symbols, the history will stop returning the proper amount of days requested.
The workaround is to close-down Matlab (IQF connection may remain open) and open it again.
Are there any troubleshooting means, any diagnostic commands that could help - for example assess if the connection to IQFeed is still operational ?
I assume I'm not the only one trying to download the components of an index from within matlab - are there any working samples available anywhere?
Thx
