I'm a little confused, so the "Holy Grail" is what? A trading system, an expert adviser, an automatic trading program??
Theoretically, it could be all three and more. In other words, it is whatever would work for you as a Holy Grail so to speak.
It really boils down to what you expect from forex trading and what you are willing to do. For some they may dream of a system that you just set and forget, leave the system trading automatically while reaping the benefits. Others would want to play a more proactive role, doing the analysis within a systems parameters and trading accordingly.
Whatever their views and expectations, the fact is that the reason why it is a Holy Grail is because of its elusiveness and unlike the real Holy Grail, what appears to be THE SYSTEM now, could very well be passe' a few days, weeks or months down the road.
