LEAPS at IB?

Can LEAPS be traded at IB? Where to find the symbols?

Mainly index.

 

I would think anything listed can be traded. Why would you think otherwise? Nothing special about a leap, just time.

 

Can't find them in TWS.

 

What is the last date and month you can find for index symbol options?

For the symbol SPX TWS shows me DEC 2011 as the last expiration offered. DEC 2011 is as far as LEAPS go for SPX.
