recomended american trading sites

Good morning

After a couple of years subscribed to a renewable energy newsletter and following their recomendations without trading I am ready to start trading.

I need some help or recomendation on how to, for newby, trade in american stocks from the UK. Can anyone recomend a site or should I speak to my bank Barclays?.

many thanks

tradestation.com

and for futures, try infinityfutures.com
they have a demo version of a trading ladder you can try out - scary stuff !!

Thestreet.com and Marketwatch.com are extremely useful.

Currently I'm bullish on Visa, Transocean and National Oilwell Varco Inc.
