Interesting. I wonder if it will attract much interest or end up another dead product. Speaking of which whatever happened to those real estate contracts? Did they ever get any volume.
Doubtful the digitals will see any volume. A exchange offering of path-dep exotics; touches, doubles and various knockouts/ins with fixed-strikes and expirations would be a major development.
a bit late innit... binaries on USDJPY, EURUSD etc swap rates would be more interesting and likely to attract longer interest i'd think... good development though...
