I sat with FXF and EUO for about 2 years waiting for this to happen. It seemed inevitable.
When the dust from SNB's move settles in a week or so, I think it is almost surely correct to write EUR puts, perhaps 4 or 5 handles out of the money, and pocket the premium. For SEVERAL months, unless the psychos at ECB decide to do a Bernanke and print the hell out of Euro.
Frankly, just now, I'd much rather sell coffee puts. Look at the 160 March puts expiring 2/13, for example.
Good trading to you!
