What you're talking about is the holy grail, and it simply doesn't exist. You may have an EA that can pass 10 year back tests, but that is still no guarantee it will continue to profit into the future. Every EA has weaknesses. Let me repeat that ... Every EA has weaknesses. Just like every trader wins and loses trades because no trading method is infallible. Of course my EA can wipe out an account, but I've taken a lot of precautions to avoid that. It has several parameters that can be changed to make it run safer or more dangerous, depending on the mind set of the trader.
I'm sharing this because I think it has potential to be very profitable. I'm not trying to sell it, people can use it, or not use it at their discretion.
Of course I don't use it, bc i don't need it as u easily can see on my portfolio.

My systems are full adaptive after many years of development together with trader friends. They contain marty elements and hedges instead of stop loss.
What i try is to give u some of my experiences with marty systems. Not less, not more. If your ego doesn't allow this, sorry, I had good intentions..
I wish u the very best and good luck on trading!
