Before revision:  This work make a substantial progress toward the solution of ultimate market dynamics problem: an evidence of existence (or a proof of non--existence) of an automated trading machine , consistently making positive P L trading on a free market as an autonomous agent , i.e. to decide whether market dynamics equation exist.
