"This is an excellent value, the system is generous (allowing for 500 stocks) and stable (and really is tick-by-tick), and the support is fantastic." - Comment from Shirin via Email

"Thanks for following up with me. You guys do a great job in tech support." - Comment from Phelps

"IQ feed works very well, does not have all of the normal interruptions I have grown used to on *******" - Comment from Mark

"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

"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

"I just wanted to let u know that your data feed/service is by far the best!!! Your unfiltered tick data is excellent for reading order flow and none of your competitors delivers this quality of data!" - Comment from Peter 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

"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 noticed that ******* quotes locked up shortly after the interest rate announcement yesterday while yours stayed stable." - Comment from Ron in Utah

"Just a thank you for the very helpful and prompt assistance and services. You provided me with noticeably superior service in my setup compared to a couple of other options I had looked at." - Comment from John

Front-month symbols will remain unchanged. NOTICE: DTN.IQ users who have workspaces or watchlists setup using the month/year code symbols for these symbols will need to update thier workspaces and watchlists to the new symbology! Examples: Currently the symbol for the CORN MAR 2010 contract is CH0. On January 31, 2010 this symbol will become CH10 Currently the symbol for CORN MAR 2010 Call at 110.00 is CH0C1100. On January 31, 2010 this symbol will become CH10C1100 Currently the symbol for CORN MAR 2010 / SEP 2010 spread is CH0-CU0. On January 31, 2010 this symbol will become CH10-CU10 Currently the Symbol for the CORN Front-month contract is C#. This will remain unchanged and continue to be C# after the transition.

DTN_Jay_Froscheiser -VP, Product Operations- Posts: 1746 Joined: May 3, 2004 DTN IQFeed/DTN.IQ/DTN NxCore	Posted: Mar 12, 2010 11:07 AM Msg. 3 of 3 In order to ensure the best support for futures, futures options and spreads contracts that trade further out than 10 years, DTN.IQ/IQFeed has transitioned its futures symbology to a 2-digit year-code format. Although this change was released to customers on March 1, 2010, we have continued to support the old 1-digit year-code format in order to provide a smooth transition for our customers and 3rd party software providers. Effective April 5, 2010, DTN.IQ/IQFeed will only support the new 2-digit year-code symbology. In order to ensure your charts, watch lists, spreadsheets, etc continue to function beyond April 5, please modify your software to utilize this new symbology now. Using the older 1-digit year-code symbols after April 5 will cause you to receive an "Invalid Symbol" or similar error. Examples: If you currently use @ESM0, you must change to @ESM10 If you currently use QCLJ0, you must change to QCLJ10 If you currently use @CZ1, you must change to @CZ11 If you currently use +CK0, you must change to +CK10 If you currently use any "front month" symbology that ends in "#", there is no change needed.
