If we talk about Fondex, it's a great cTrader broker with the best trading conditions. I trade manually, I don't use advisors.
Have you ever flown a plane without pilots on full autopilot? Of course not! Imagine that the security of your account is in full control of your advisor. By launching it, you give it the full right to use your account! I often see ads and offers to buy Expert Advisors, and there are a lot of stories about making money on free Expert Advisors in two days! Think about it, what kind of fool would give his brainchild for nothing, especially since the more people try it, the less effective it will be.
