well of course he is guilty, but actually is he legally liable probably not..
you gave him him your accounts to trade however they liked, why would you even do that, they are not a registered finacial services firm. Their website is full of the typical get rich quick stuff and I quote
"You Can Have 10% to Over 50% Huge Mind-Boggling Returns, or More, Weekly... Most Weeks. It is True when You use Our EA. Try us And See For Yourself What Our EA Can Really Do For You."
did you really believe that?
I will voting guilty because it is so obvious but please please please will people learn from this..... Nobody, least of all non-registered individuals or bucket shop companies are going to trade your money for you and return you loads of cash.
Companies trade other peoples money for the churn - the turn over - because they make on every trade and of course with the bigger more reputable companies the annual management fees as well. Nobody is going to hand anyone 10% profit per week.
