Can I end up owing the broker money?

Ive been reading a lot here and been practicing on different accounts for a couple of months (I really like the forex.com software). Before I go trading real money Ive got one question… can I end up owing the broker more than my investment if I wreck my account? If not then I think I will give a real account a go. :). Also can anyone recommend a broker for the UK that I wont owe more than an initial investment to if different brokers have different policies regarding this?

Thanks.

Most brokers will close your trades out before that happens.

BUT, should you make a foolhardy trade, and leave it open over the weekend, and for some reason, the gap is larger than your margin allows, yes.

However, if you practice good money management, and religiously employ stops, you should never have an issue arise such as that.
