This is such a broad question lol there is no holy grail, gotta learn - it your strategy isn't working go back to basics.
Yes it's true that there is no such thing as a holy grail EA or best EA for everyone as everyone would have a very different expectation on what kind of EA they want and what trading style they prefer. Some don't like martingale, some like hedging, some prefer grid trading, some expect to earn a 50% profit or more per month, some would only expect to earn around 10% which is good enough for themselves. So on and so forth.
As for me, there are two important factors in terms of finding a good EA:
1.) An EA that is able to perform reasonably stable and consistent over a long period of not just days but months and even years.
2. ) Finding settings that work well at least for myself in terms of not only earning profits but effective in managing risks over not just days but months and years.
Having said all that, to be honest until today I still haven't found one that has checked all the lists yet. But, I'm not giving up just yet, still keep on looking for one or two that could possibly be my favourite EA in the near or far future.
At the moment, I still believe that there should be some EAs that are reasonably good and reliable out there. The only thing matters is the setting. One of them is "Life Changer" EA. Many have been testing it and so far none have said that it is a scam EA. The only thing is that one would need to find is the settings that work well over long term.
