i'm answering in a perspective of an end-user within the united kingdom. most stockbrokers won't provide real-time information without 'level 2' access, however this comes free for most who trade over a certain threshold. if you're like me, who trade within their isa holding each year, you need to look elsewhere.  i personally use ig.com. they've recently began a stockbroking service, whereas this comes with realtime information etc with a paid account without any 'threshold'. additionally, you may want to look into cfds/spreadbets as these, won't include the heavy 'fees' and tax liabilities that trading with stocks may bring.
