trendie said:I have asked this precise question to them a short while ago.
They said you cant have multiple accounts, and segregate monies.
( I wanted to separate a "live" trading account from a smaller "system test" account where I could mess about with new ideas with real money. )
They said NO.
I am sure I read somewhere( may have been CMC ) that the other person can open their own account and give you written permission to access and trade their account for them.
I have two accounts with CMC for the reason that I do some short term trading in one and longer term stuff in another.
