Thanks @CavaliereVerde for all the research, Equity is definitely a major factor to choose a good Darwin. We are not talking about millions of equity here, only a few thousand.
I will never invest in traders who only willing to put hundred of dollars in their own strategy. And I do not believe in such "poor" traders as well, poor people who don't have a few thousands can't even afford to have computers, they have to work everyday to make ends meet.
So it's easy to conclude that traders who put in only hundreds in their account are not serious in their trading business, who are not willing to put effort to work and save some capital for this business, there are no show of "Patience, Passion and Commitment" which is very important in this business.
