A friend of mine is thinking about opening a Bitcoin exchange and I told him I'd see what the community is looking for. I know a lot of the exchanges have problems so I'm wondering what you would like to see in the 'perfect' exchange?
Two things I would want to see in a new exchange:
1) Lots of volume!
Not sure how an exchange could compete with Mt Gox on that, maybe with lower fees, awesome data/trading interface?
2) Stop Loss Orders!
Mt Gox to their shame does not have this most basic trading function...arrrghhh!
