"After all the anxiety I had with my previous data provider it is a relief not to have to worry about data speed and integrity." - Comment from Eamonn

"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

"I've never had DTN go out on me since switching. ******* would go down a couple times every month when I was using them." - Comment from Bryce in AL.

"And by the way, have to say this. I love the IQFeed software. It's rock solid and it has a really nice API." - Comment from Thomas via RT Chat

"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum

"I'm very glad I switched to IQFeed. It's working perfectly with no lag, even during fast market conditions." - Comment from Andy via Email

"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

"I'm satisfied with IQFeed. It's the most reliable and fastest quote feed I have ever used. Although I'm a resident in China, it's still very fast!" - Comment from Xiaofei

"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 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

IQFeed users can watch 500, while DTN.IQ can watch 1300. Other than the above limit, Level II doesn't have any other specific limit. However, in practical use you won't be able to watch more than say 10-20 level II symbols at a time due to sheer volume of data and updates. It is definately dependant on the users machine. I have had upwards of 50 level II screens running as a test, but it wasn't too pretty. You can tell how many symbols your account is authorized for by looking at the connection manager (in the system tray) after you login. It will show Maximum Symbols as well as other stats that may be of use. Jay Froscheiser DTN Market Access, LLC.
