Quote from opt789:
I have been told that the CBOE will use the standard settlement for the new binary options on the SPX, and that the AMEX was told to use the VWAP settlement to avoid possible manipulation. Personally I would like them to add something a little more interesting like touch/no-touch, but this is a good start.
Yeah, I'd prefer the American vs. European binary. They're following the CBOT here. The logic is that users want atm options. ATM touch exotics aren't terribly feasible.
