"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
"With HUGE volume on AAPL and RIMM for 2 days, everyone in a trading room was whining about freezes, crashes and lag with *******, RealTick, TS and Cyber. InvestorRT with IQFeed was rock solid. I mean SOLID!" - Comment from Public IRC Chat

"I am enjoying the feed very much - so superior to the broker provided feed I was previously using." - Comment from George

"It’s so nice to be working with real professionals!" - Comment from Len
"I've been using Neoticker RT with IQFeed for two months, and I'm very happy with both of the products (I've had IQFeed for two years with very few complaints). The service from both companies is exceptional." - Comment from Public Forum
"I just wanted to let you know how fast and easy I found it to integrate IQFeed into our existing Java code using your JNI client. In my experience, such things almost never go so smoothly - great job!" - Comment from Nate

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
