Try www.mytrack.com . I can quote it in myTrack, but I don't know what it takes to be able to trade it there. I do know they have a UK partner, so they probably have some solution for you.
Too bad IB doesn't add the AIM stocks - there's a lot going on there.
Anybody else trading London or German stocks?
How do you see the activity or lack thereof compared to US? Same kinds of movements? More expensive to trade, yes?
