The iqfeed package provides a basic TCP/IP interface between R and DTN
IQFeed. It requires TCP/IP access to IQFeed. The package only contains
a few basic functions for historic LI stock and equity options. We plan
on added Level II and more Level I functions in the near future. The
packages returns all time series data in xts format.
Example:
require(iqfeed)
iqConf()
t0 <- "2010-01-18 15:25:00"
t1 <- "2010-01-22 10:00:00"
trades <- HIT("MSFT",interval=60,start=t0,end=t1)
daily <- HDX("XOM",days=14)
daily
# Options chain lookup example
symbols <- CEO("MSFT")
