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.
