撮合制：交易市场的核心机制

中文版

撮合制，又称为“对盘”或“匹配制”，是金融市场交易机制中的一种核心制度。在撮合制下，买卖双方通过交易平台进行交易，平台会根据价格优先、时间优先的原则，自动撮合买卖双方的订单，完成交易。

撮合制的核心在于“价格优先，时间优先”的原则。这意味着，当买方报价高于或等于卖方报价时，交易平台会优先撮合报价较高或时间较早的订单。这种机制确保了市场的公平性和效率，使得每个市场参与者都有机会按照自己的意愿进行交易。

撮合制广泛应用于股票、期货、外汇等金融市场。在这些市场中，交易平台会收集所有买卖双方的订单，然后根据价格和时间进行匹配。一旦匹配成功，交易就会立即执行，交易平台会通知交易双方。

撮合制为市场参与者提供了一个公平、透明的交易平台，促进了市场的流动性和稳定性。同时，它也降低了交易成本，提高了市场的效率。然而，撮合制也存在一些局限性，如可能导致市场的过度投机和短期波动。

The Matching System: A Core Mechanism in Financial Markets

The matching system, also known as "order matching" or "matching system," is a fundamental institution in financial market trading mechanisms. Under the matching system, buyers and sellers conduct transactions through a trading platform, which automatically matches orders between the two parties based on the principles of price priority and time priority.

The core of the matching system lies in the principle of "price priority and time priority." This means that when a buyer's quote is higher than or equal to a seller's quote, the trading platform will prioritize matching orders with higher prices or earlier timestamps. This mechanism ensures fairness and efficiency in the market, giving every market participant an opportunity to trade according to their preferences.

The matching system is widely used in financial markets such as stocks, futures, and foreign exchange. In these markets, trading platforms collect orders from both buyers and sellers and then match them based on price and time. Once a match is successful, the trade is executed immediately, and the trading platform notifies both parties.

The matching system provides a fair and transparent trading platform for market participants, promoting liquidity and stability in the market. It also reduces transaction costs and improves market efficiency. However, the matching system also has some limitations, such as potentially leading to excessive speculation and short-term volatility in the market.
