I am currently trading four accounts now of 'friends & family' now and perhaps do more if I can get around the autotrading part without any glitches.Its a good idea for any trader as trading different strategies on different accounts keeps the cash flow healthy.Have sent you a PM in this regard, mind you I am very picky
If you are looking to manage a large account I would suggest a PMS service than a broker, most brokers are just salesmen without an iota of understanding of markets.
Good luck..
