how to choose forex advisor from Metatrader

Paulo Oliveira  
 Have  bought several  EAs and none really worked, then I started studying a  strategy  mine  and brief  I am go to request in job section of  MQL5 Community.

So,  I believe that an EA can work very well, and the better, in the  MQL5 Community, I will only pay after to  test and to check that it is as my request. 
Now one thing: have to know to ask!

"Once a man found a lamp with a genie, He was entitled to one asked, then he does: "I want the best woman in the world."
The Genie snapped his fingers and the mother of the man appeared." :D
