A profitable EA doesn’t mean he/she can make you rich. At the end of the day, you can only rely on yourself. If the scheme/tactic works, why bother sharing with you? He/she will keep that in the dark and keep you in the dark. Anyway…

i bought different ea’s over the course of six months because of the ads and promises of gigantic gains only to find out the hard way of loosing half of my account. i should have known better, the ea’s i got (which happens to be one of the top five) just buy and sell like crazy, absolutely no logic.

The trouble with an EA, as mentioned in the video, is a transfer of responsibility for trading decisions from the person to the EA. So why would a person do this? Lack of experience and understanding would be my first reply. A person in that situation has two choices. Trust an EA or put in the study and hard work required to develop your own approach. In that respect, it’s not a question about EA but a more general approach to life.
