Ann: Successful launch of US Trading, page-5

10% was my conservative assumption, for boost to trades. It looks like they will probably reach that before long. >10% of active traders have signed up for a US account. Not to say that they'll all trade, since a lot would just want to option to be available in their account. But it seems to be going nicely anyway, and it's boosting regular sign-ups, which should help to keep sign-ups near record levels for a while longer, instead of pulling back somewhat.
