点差是什么啊？

中文版：

点差，也称为差价或价差，是金融市场中常用的一个概念，主要出现在外汇、差价合约（CFD）等金融产品的交易中。点差代表了买入价与卖出价之间的差额，也就是投资者为进行交易所需支付的成本。

在外汇交易中，点差通常表示为货币对的两个汇率之间的差额，例如，EUR/USD的买入价为1.1000，卖出价为1.1002，那么点差就是0.0002，也就是两个小数点后的第四位。点差的大小会受到多种因素的影响，包括市场的波动性、流动性、交易时间、交易平台的差异等。

点差对于投资者来说是一个重要的考虑因素。较小的点差意味着投资者进行交易时需要支付的成本较低，从而提高了投资效益。因此，许多投资者在选择交易平台或经纪商时，会将点差大小作为一个重要的参考指标。

What is Spread?

Spread, also known as difference or price gap, is a commonly used concept in financial markets, especially in trading financial products such as foreign exchange and Contracts for Difference (CFD). Spread represents the difference between the buy price and the sell price, which is essentially the cost incurred by investors to conduct transactions.

In forex trading, spread is typically expressed as the difference between the two exchange rates of a currency pair. For example, if the buy price of EUR/USD is 1.1000 and the sell price is 1.1002, the spread would be 0.0002, which is the fourth decimal place. The size of the spread can be influenced by various factors, including market volatility, liquidity, trading hours, and differences in trading platforms.

Spread is an important consideration for investors. A smaller spread means lower transaction costs, thus improving investment efficiency. Therefore, many investors consider spread size as a key factor when choosing a trading platform or broker.
