"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob
"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
"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 am keeping IQFeed, much better reliabilty than *******. I may refer a few other people in the office to switch as well." - Comment from Don

The Options Symbology Initiative (OSI) is an industry plan to change the symbology used in representing options listed contracts. The OSI is being coordinated by Options Clearing Corporation (OCC). As a result of this initiative, DTN will be changing its Options symbology for all DTN platforms and begin disseminating the new equity and index symbol format in accordance with the OCC and Options Symbology Initiative.


OCC Implementation Schedule:
• September 2009 - January 2010 - Scripted industry testing of the new environment under OSI pre and post symbol consolidation.
• February 12, 2010 - Mandatory cut-over for use of explicit data elements by all market participants .OPRA codes become obsolete and will be suppressed from all data interfaces on this date. (Symbols will not be consolidated at this time but all explicit data elements must be used).
• March 2010 – May 2010 – Execution of the symbol consolidation strategy that mitigates operational risk and ensures an efficient consolidation of all open interest.

Anticipated DTN implementation date: January 30, 2010
