See chart, When you have time check out Wyckoff “Composite Man” method. Wyckoff proposed a heuristic device to help understand price movements in individual stocks and the market as a whole, which he dubbed the “Composite Man.” ”…all the fluctuations in the market and in all the various stocks should be studied as if they were the result of one man’s operations. Let us call him the Composite Man, who, in theory, sits behind the scenes and manipulates the stocks to your disadvantage if you do not understand the game as he plays it; and to your great prot if you do understand it.” (The Richard D. Wyckoff Course in Stock Market Science and Technique, section 9, p. 1-2).
