Some forex brokers like Oanda offers the options of opening more than one account under the same client name. From what I see, is this going to invite abuses? I can think of 2 examples. 1) Create track record. Open two accounts under the same name and do the opposite trades. One side wins and the other loses. The winning side will have a "track record" after say 1 - 3 years. 2) Money Laundering. Again, open 2 accounts and do opposite trades. The winning account can be used to prove that wealth is created from trading gains. Any thoughts why the options of having 2 or more accounts are even allowed given the potential abuse?
