The term "mouse pool" refers to the practice of influential players or institutions in the stock or other securities trading markets using their financial advantages to seek personal gain by manipulating market trends through advance buying or selling. This kind of behavior often comes at the expense of other investors, and is considered unethical.

In the stock trading market, the "mouse pool" typically involves institutions or insiders with significant funds. They can use their financial strength to engage in heavy buying and selling, thus controlling market trends. When market conditions are good, they may buy heavily to drive up share prices, and when market conditions are poor, they may sell heavily to depress share prices. In this way, they can reap huge profits, but also cause losses to other investors.

The "mouse pool" practice is unethical because it comes at the expense of other investors. This kind of behavior not only violates market rules, but also undermines the fairness and stability of the market. Therefore, the practice of the "mouse pool" should be firmly resisted in order to maintain market fairness and justice.
