市场中有N个交易主体（Agent）对同一支股票进行交易，根据采用的市场策略将市场交易者分成三类：基础分析交易者，乐观主义交易者和悲观主义交易者。

市场环境的变化会引起交易主体行为模式的转变。由于不同市场策略之间的利润差异， 交易主体会由一种交易策略(如乐观主义交易者)转变为另一种交易策略(如基础分析交易者)。

个体交易者行为(体现在交易者类型及交易者类型的转变)及其相互作用形成整体市场现象，而市场环境又影响个体交易者调整自己的行为模式，形成不断演化和发展的复杂适应系统。

-There are N trading agents in the market to deal with the same stock. According to the adopted market strategy, the market traders are divided into three categories: basic analysis trader, optimist trader and pessimistic trader.

Changes in the market environment will lead to changes in transaction behavior patterns. Because of the difference in profit between different marketing strategies, the transaction subject is transformed　one trading strategy (eg, optimist trader) to another (such as the fundamental analysis trader).

The behavior of individual traders (which is reflected in the change of the types of traders and the types of traders) and their interactions form the overall market phenomenon. The market environment also influences the individual traders to adjust their behavior patterns and form a complex adaptive system that evolves and develops.
