Well, IB do their best to discourage inexperienced traders, and they succeeded in my case :-)
All those things like: 'you need to consider the trade rules of the exchanges your order may be routed to' don't sound like much fun. I understood, when I visited the Motley Fool, that you may have trouble buying odd lots, precisely because of this. But that was some time ago, and I don't know the current situation. And it may not bother you!
