"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

Its' use is limited to launching the executables and using the COM interfaces or TCP/IP socket to request and receive data. It is not a development library and no option is provided for direct connections to our servers or including components of the API into your own developed code. Two types of interfaces are used in the IQFeed API: a socket based interface for streaming data, and COM or TCP/IP based interfaces for lookups and historical data/news retrieval. Essentially, there are TCP connections and protocol definitions for you to use. Your app talks to IQFeed client software, not the servers directly. Jay Froscheiser DTN Market Access, LLC.
