There happens to be ONLY ONE HOLY GRAIL in the world of Investing and Trading. That holy grail is that there IS NO HOLY GRAIL. Certain rules/formulae work in certain markets during particular phases, others don't. The key lies in recognizing WHEN what strategy/formula is effective and when it isn't. With hindsight and with a statement like "I cannot reveal the secret formula" it is easy for one to prove almost any movement in mkts and how one could have profited from them. It is not my intention to be offensive, but if you can prove the same results in real-time, I truly, truly and whole-heartedly salute you.
