Since the author of the EA recommended the broker OctaFX for his EA, I went to check the Client Agreement from this broker. It raised my concern on clause 4.9. With this clause the broker has the right to null all profits earned by the EA.
4.9. In exceptional cases short-term orders lasting less than 180 seconds can be cancelled should they be considered an abuse.

Closer look at the closed trades done by the EA. Most trades closed shorter than 180 seconds, giving room for broker to null these trades, if they wanted to.
I'm not against this wonderful EA, but on the choice of the broker. Hope the author could test and recommend other brokers that his EA could run profitably on. Thanks.
