Outside of the US, what are the most active option markets? Thinking about dabbling with some foreign option exposure.
If you include index options, Kospi200 is by far the the most active issue, and it is available through IB.
I don't follow the options, but it's worth remarking that Kospi futures are now "legal" - http://www.cftc.gov/newsroom/generalpressreleases/2008/pr5574-08.html
I looked into this too, and as far as I could tell the only index or index futures options available that us legal residents are allowed to trade are n225 options on the Singapore exchange. If somebody knows differently please let us know.
Looks like Interactive Brokers offers equity option trading on international exchanges. Does anyone do that with IB? If you want to trade on the DAX, do they convert your USD balance into Marks?
