Pricing model in the securities market taken into account of investor stratification

This article develops the specified model, the relevance of which is undoubted, i.e. it describes the pricing process as an event that depends on the main factor in the pricing of the securities market - the composition and structure of investors and their strategies. The existing pricing models used are the expression, using mathematical expressions, of price movements during trading, which examine the dynamics and patterns of price movements without taking into account the stratification of investors. The main form follows from these models - in them prices are considered as a kind of independent stochastic process, described by the Elliott wave theory and Fibonacci numbers. However, behind the price movements during trading are specific market strategies of investors (participants). The behavior strategies of bidders depend on their personal interests: whether they want to sell instruments at a higher price or buy them at a lower price. And the prices of instruments depend on who is more on the market at a particular period of time or during a particular operation - sellers or buyers. It follows from this that the number of investors of one type or another actually determines the price of the instrument being traded at a specific period of time or during a specific trading session. If such a dependence can be traced, then the mathematical description (modeling) of this phenomenon of the securities market is indeed a relevant topic for research.
