Abstract:
1. A fluctuation of prices predicting device for market price time-sequence data of an open market, said device comprising: holding/preserving means for holding/preserving theoretical models of correlation functions, wherein said models are generated based on a price elasticity and market uncertainties; acquiring means for acquiring sampling data by sampling a local portion of the real time-sequence data; generating means for generating a real correlation function based on the sampling data; selecting means for selecting one of the theoretical models that best matches the real correlation function, and judging one of the states regarding the real market price time-sequence data; and indicating means for indicating a fluctuation of the real market price time-sequence data based on a relation established between the price elasticity and the market uncertainties of the selected theoretical model; wherein the theoretical model of the correlation function is generated based on the following: real time-sequence data having a virtual equilibrium price that is provided by multiplying the market uncertainties by a recent change value of the real market price time-sequence data; and a value of the real market price time-sequence data after a time Δt that is provided by multiplying the price elasticity by a difference between a value of the real market price time-sequence data in a current time t and the virtual equilibrium price.
