Long time lurker, first time poster. Basically, I developed a model for the implied volatility smile that works well on S&P500 and crude oil options. Before I start trading, however, I want to see if this also works on other markets. So I need live (or slightly delayed, 15 mints is ok) option quotes for several international indices. Such as FTSE, DAX, CAC, Nikkei, Hang Seng. Anybody knows where can I find data for these? If it's free it would be nice, but pay service is OK too. Any help is appreciated.
