Abstract: The nonlinear science not only widens our sight and liberates our idea, but also
had become a effective means to solve complex systems problem. The trade price
fluctuation in finance market (stock and futures) is nonlinear. It can but a nonlinear
equation group to describing the price, and solitary wave is just the key of the seeking
group. The speculation model on trade price fluctuation in finance market is the seeking
approach Keynes’ “beauty contest”. The finance epoch will be come forth on the theory
of complex systems and nonlinear dynamics in new century.
