"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 would just like to say that IQFeed version 4 is running very well and I am very happy with its performance.

"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

"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.

DTN has released an enhanced symbol lookup/search tool on our websites that will make it easier to find the symbols you are looking for. In addition to new search criteria and filters, we have also updated the format of the master symbol file we make available to our customers. The enhanced format master symbol file is updated daily and available for download by visiting and selecting “Symbol Look-Up”. The old format master symbol file ( will no longer be available after August 31, 2009.

Overview of the enhancements to the online Symbol Lookup tool:
The new search has multiple filter levels and search options.
• SIC/NAICS Code Search: Search by NAICS or SIC code and receive all the symbols that make up that industry segment
• Security Type Filter: Restrict the results to a single security type (ie. if you only want the futures, not stocks, options, etc, you should choose “Future”).
Search Options:
o Show Front Month Only: Restricts results to only the front month contracts as identified by the DTN Ticker Plant
o Show Combined Session Only: Restricts results to symbols starting with “+”
o Show Continuous Contracts Only: Restricts results to symbols ending in “#”
o Show E-Minis Only: Restricts results to Listed Market of CMEMINI, CBOTMINI and NYMEXMINI.
o Don’t Show Options: Eliminates Security Type of “FOPTION” and “IEOPTION” from results
o Don’t Show Spreads: Eliminates Security Type of “SPREAD” from results
o Output Symbols Only: Allows user to cut/paste the symbol list results from the webpage into DTN.IQ, ProphetX and other apps.
