### Abstract

In this paper it was developed a modification of the known multiagent model Minority Game, designed to simulate the behavior of traders in financial markets and the resulting price dynamics on the abstract resource. The model was implemented in the form of software. The modified version of Minority Game was investigated with the aim of reproducing the basic properties of real financial time series. It was proved that such properties as the clustering of volatility, the Levy distribution and multifractality are inherent for generated by this version of the Minority Game time series of prices. PACS 89.65.Gh 1.

Fractal dimension In the definition of fractals, the main idea by Mandelbrot =-=[13]-=- has been related with the notion of selfsemilarity. In other words fractals are scale invariant objects. This scale invariance may be exact or statistical. It can be shown [13] that for fractals obje... |
