Mark Fisher, Richard Dennis and surely others have taught others. These guys do not worry about losing any "EDGE". Mark also says it helps his clearing business by getting traders to follow his methods and stick around.
I, as stated before, thought Marks method was like "MINE" so i bought the book to review his ACXD method. YEP, quite like my own ideas. The point being that my "PERSONAL" discoveries in the mkt are NOTHING NEW. Another sameness of methods also appears in another persons works, naturally with some different wrinkles and twists, but in GENERAL, the same stuff. That working method is from John Clayburg called the Directional day Filter.
My simple version of trading off the open range, open bar, open price (take your pick) is basically as theirs and others methods.
The fun part of my method was NOT discovering it in someones book, but to come up with the method on my own from actual trading under live fire. That is the only way to learn, that is the best teacher, good ole "OJT" on the job training......
In a old war movie the other day: "A wing and a Prayer" the navel Officer says to the other guy who was questioning an ORDER from the superior officer. The Commander said to the guy: "Your duty is NOT to question any order, Your duty is to FOLLOW the order WITHOUT question"........
Can that be taught in a non-military situation? i think so, but it is harder to drill into someones head that trading is also a life or death situation and orders ar to be followed.
