什么是外汇交易？
外汇交易，简称 FX 或FOREX，即 Foreign Exchange 的缩写，简单说就是将一种货币兑换成另一种货币。外汇市场是目前全球规模最大、波动性最强的金融市场，每天的交易量约为5万亿美元。
外汇交易跟股票交易有些相似，如果股票交易者认为某支股票的价格将会在未来上涨，他就会买入这支股票，而他认为某支股票的价格将会在未来下跌，他将会卖出这支股票。同样地，如果外汇交易者认为某货币对的汇率将在未来上升，他就会买入该货币对，而他预计某货币对的汇率将会在未来下跌，他将会卖出该货币对。
外汇市场产生的原因
外汇市场，是指从事外汇买卖的交易场所，或者说是各种不同货币相互之间进行交换的场所。外汇市场之所以存在，是因为：
贸易和投资
进出口商在进口商品时支付一种货币，而在出口商品时收取另一种货币。这意味着，它们在结清账目时，收付不同的货币。因此，他们需要将自己收到的部分货币兑换成可以用于购买商品的货币。与此相类似，一家买进外国资产的公司必须用当事国的货币支付，因此，它需要将本国货币兑换成当事国的货币。
投机
两种货币之间的汇率会随着这两种货币之间的供需的变化而变化。交易员在一个汇率上买进一种货币，而在另一个更有利的汇率上抛出该货币，他就可以盈利。投机大约占了外汇市场交易的绝大部分。
对冲
由于两种相关货币之间汇率的波动，那些拥有国外资产（如工厂）的公司将这些资产折算成本国货币时，就可能遭受一些风险。当以外币计值的国外资产在一段时间内价值不变时，如果汇率发生变化，以国内货币折算这项资产的价值时，就会产生损益。公司可以通过对冲消除这种潜在的损益。这就是执行一项外汇交易，其交易结果刚好抵消由汇率变动而产生的外币资产的损益。
什么是差价合约?
差价合约，简称 CFD ，即 “ Contract For Difference ” 的缩写。差价合约是一种金融衍生工具，主要包括外汇，大宗商品，股指和股票等。差价合约是这样一种交易，双方达成协议从开始交易到交易结束，根据标的资产的价值变动差来交换金钱。交易者交易差价合约意味着他们从来没有真正拥有标的资产，只是通过产品的价格波动进行投资或投机的交易。
