Interactive Brokers

To go further, you can cross-reference some of this stuff with the IB 
API docs. 

I'll underline this statement.  The IBrokers package is 'just' an R
wrapper for the IB API.  Things like valid message types, contents of
messages, data formats, etc. have been wrapped for R, but the *values*
are those defined by IB's API.

Cheers,
