Busiest Electronic Option Markets

[enterthe]

What are the most active electronic option markets.

I've been looking at the Eurostoxx options on Eurex, but none of the volume seems to go through the order book and I believe that most of the action is done over the phone.

Enterthe,

Attached is an Excel file with yesterday’s DAX volume plus another day’s chosen at random (10 Sep). Pretty good volume (better than LIFFE’s/Euronext’s index options).

See the two attached pdf files re Eurex’s options trading procedures.

Grant.
