[amibroker] IWM and QQQQ for IB plugin

["sursod" <sursod@xxxxxxxxxxx>]

My Amibroker IB plugin tells me the symbols IWM and QQQQ are no longer 
valid. IB tech support is not answering and I cannot find answer in 
thier online Help. The weird thing is my TWS continues to get quote 
from these symbols.

Does anyone know the new symbols for IWM and QQQQ for use in the IB 
plugin, may be we have to type strings now? 
Thanks,
Sursod
