Would be any type of strategy that could be traded across a basket or markets or just a few markets with relatively low drawdowns and consistent returns relative to the markets volatility. Also, something simple and not overly complex
My guess is that the only time that you will separate all of your emotions from any activity you engage in is when you are no longer among the living. However, I imagine that you will engage in relatively few activities at that time, so it may be a moot point.
The term "holy grail" in its usual interpretation means 100% wins, "perfect" system. Anyone with half a brain understands that noone needs such a holy grail to be a successful or very successful trader. Noone needs to have 100% wins to make tons of money. OK? Obvious. So what IS needed? What is needed is an edge (a method) that gives you CONSISTENT PROFITABILITY. CONSISTENT PROFITABILITY is when you look at your equity curve over last 5 years and it's nice and smooth and looks like a 45 degree diagonal or steeper. That's what we all are trying to achieve. Anything that provides us with that result *is* the best we can achieve. Again, noone needs 100% wins.
Added by Sunnyskies: The HG does NOT need to win 100% of the time but DOES need to have a smooth equity curve "like a 45 degree diagonal."
