摘要翻译：
在本文中，我们继续系统地分析了以前在经济背景下提出的操作方法，并讨论了一个简化股票市场的{\em混合}玩具模型，即一个以股票价格为输入的模型。我们推导了市场上各种交易者的投资组合的时间演化，以及其他{\em可观察}量的时间演化。与前文一样，我们用{\em类不动点}近似求解运动方程。

英文摘要：
  In this paper we continue our systematic analysis of the operatorial approach previously proposed in an economical context and we discuss a {\em mixed} toy model of a simplified stock market, i.e. a model in which the price of the shares is given as an input. We deduce the time evolution of the portfolio of the various traders of the market, as well as of other {\em observable} quantities. As in a previous paper, we solve the equations of motion by means of a {\em fixed point like} approximation.
