...And? Good experience? bad? Good liquidity? Good prices? Good interaction with customer service? Good statements?
It's pretty new, so liquidity isn't all that great. They don't take the other side of your bet. You can place a bet, or look and match another user in the order book.
They just made some alliance with the CBOE to increase traffic. They give you first 30 days free from transaction costs, after that it's like a buck fifty(less if you trade size). The spreads are pretty tight from my experience.
I have not had interaction with customer service(haven't needed to), their statements are good. You get email'd fills, orders, statements, and can trade many macro events, housing #'s, employment, etc.
Overall, this is a good primer for the binary market w/out getting involved with the I-banks to place trades, where the notionals are out of reach of most of us retailers.
Liquidity needs some work, but you can start with very little capital. I give it a B.
