Basically, you know, by some tricks, they can make a profit in a few months , even a year (it is normal : Martingale ... ) , but who know, your account (may be) can be blow away in next month. but i still believe in ea, so, you should research more about your ea , at least, you should know how it work, or, test it over a period of time (may be 6 month, or 1 year), see how ea manages risk , if it's safe, congratulations, you got good ea. "you can not fly , if never try", try it, and it will become your experience (that's just my personal opinion)
