IB Help

["Joe Landry" <jelandry@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>]

Would appreciate some help in identify the ticker symbols for the common indices to 
use in IB.   For example I find that COMP works in IB as the NASDAQ composite 
but when I enter this symbol in AB and try to access it via the AB IB plug in
 I get the message that COMP is an invalid ticker.  

What am I missing?  How does on go about setting up a standard set of tickers in AB RT/IB plug in?  

Thanks
Joe
