I think: Those profound principles, the correct interpretations of these subtle principles, and the associated know-hows for aligning oneself with them are All 'hard-to-find' Edges, aren't they? lol
My post wasn't about semantics. Generally speaking, when people refer to edge (at least here on ET), there is a connotation about it being something esoteric, hard to find, etc. Perhaps some of those who are successful feel the need to make it sound difficult. This is no surprise, as the same tendency exists in Religion and Academics. This creates a culture of searching for tactics and tools rather than expending effort in understanding the market. My point wasn't about whether aligning oneself with principles is easy or hard or whether they are subtle and profound. They may or may not be. The understanding that one is on a sailboat may encourage the explorer to stop rowing the boat with his hands. Such an understanding may actually encourage him to expend his energies on learning how to unfurl the sails. He may then start noticing the phenomenon of 'wind'. Hell of an 'edge'. This does not mean that it will all be smooth sailing with never a storm. But hey, we are at least out of the harbor and on the high seas. I believe this was what Acrary realized and shared with us.
I just realized that this above quote by Keynes is a brilliant answer to the question 'What is Technical Analysis?' or 'Does Technical Analysis work?'.
Ten years ago and further back I designed complex systems cause I thought wrong, I wanted to beat the Professionals, I thought that is how the game is played to make profits. Cause of medical reasons, I had to radically change to KISS systems as I no longer have speed, hands shake and recent memory comes and goes, but KISS systems simply do far better. And beating the Pro's is all wrong, whether very Long term or Scalping, I just coat-tail them. BTFD
