Just a comment on the lack of a direct R API for non-IBrokers
brokerages: of course its possible to put something together using
rJava or a direct C interface, but it's not the smoothest thing if
you've never delved into the R internals and it's not quite the
fastest thing in the world if you are doing particularly
time-sensitive work. At lower frequencies, this becomes less of an
issue and simple work-arounds like using a csv file as an intermediate
can make everything much easier.
On the other end of the trade process, once you start getting into
more HF domains, there's also the inverse problem of real-time
processing: I'm not particularly interested in the question so I
haven't thought much about it, but I don't see a particularly R-ish
way to deal with a live data feed, though it's been dealt with in the
R-SIG-Finance archives a couple of times.
