There's just one question that many people along with me will ask you.
If you are so good at trading then why don't you trade yourself at first place ?
Why bother to trade for others when you can take the profits for yourself.
Even if you say that you don't have the funds to trade then you can simply take a loan and pay back from the profits you get.
Besides that, what are the proofs that you can show to justify your skills.
Well, he has already mentioned that he has no access to loans or funds and hence he cannot do trading on his own. However, it's hard to trust anyone especially if anyone is asking to manage the trading portfolio.
I know people who start giving such services because there is no loss in this type of service for them but only the person whom they are managing the account loses. As long as the trades go in profit, these people keep on earning free commission etc and one day they liquidate all the money due to any wrong trade and go away leaving the original investor in the loss.
