Probably a roundabout way to do this would be to use Rserver and write a 
Java app using the Rserver wrapper to issue command reqHistoricalData at 
X intervals (setup a Java timer object or loop) and place orders (via 
the same java program connected to the RS wrapper) using twsOrder and 

I'm not too familiar with callbacks and such in the IBrokers package.
