  GRAPHICAL ANALYSIS TECHNIQUES OF MARKET TRENDS

  The current research paper presents a comparative analysis of the various types of charts that are normally applied in trading financial instruments. Patterns that are applicable in European as well as in US and Japanese practices are systematized. The study systematizes the „price models” of trend analysis. The peculiar features of the „turning” ... The current research paper presents a comparative analysis of the various types of charts that are normally applied in trading financial instruments. Patterns that are applicable in European as well as in US and Japanese practices are systematized. The study systematizes the „price models” of trend analysis. The peculiar features of the „turning” and the „continuing” models are revealed. Some of those models are proved to bear prognostic authenticity.

A dynamic economic process is modeled, which occurs in conditions described by a stochastic differential equation. The dynamics of the process is subject to jump-like changes. Such systems are known as Markov jump linear systems. The target in the observed process is modeled through a functional which has to be minimized. The result is a linear quadratic stochastic model. The equilibrium search model is related to the numerical solution of a system of generalized discrete-time algebraic Riccati equations. Methods for finding the maximal solution to a system of discrete-time algebraic Riccati equations are investigated. Moreover, new methods and algorithms for computing of this maximal solution are proposed. The numerical characteristics of algorithms are analyzed in special cases of negative definite weighting matrices and indefinite weighting ones. Conclusions are derived of the applicability and efficiency of the proposed methods.
