在外汇交易市场，货币成对交易。货币对的两个组成币种相互关联、不可分割，货币对的两个组成币种在交易中互相兑换，一种货币的价值相对于另一种货币报价。例如欧元对美元为 EUR/USD，称为货币对。报价 EUR / USD = 1.1500 意味着 1 欧元兑换 1.1500 美元。在这种情况下，EUR 是基础货币，USD 是报价货币（计数货币）。这代表 1 欧元可兑换 1.15 美元；或是购买 100 欧元需要 115 美元。
- EUR/USD (Euro-zone/ United States)
- USD/JPY (United States/ Japan)
- GBP/USD (United Kingdom/ United States)
- USD/CHF (United States/ Switzerland)
- USD/CAD (United States/ Canada)
- AUD/USD (Australia/ United States)
- NZD/USD (New Zealand/ United States)
现货外汇仅以特定金额进行交易，称为口数，或基本上是您将买入或卖出的货币单位数量。例如，1 口 EUR/USD 等于 100,000 美元。目前所有外汇经纪商都允许客户交易数量最小至 0.01 口（1 微型口数，相当于 1,000 美元），以及提供杠杆操作，这意味着您无需存入 100,000 美元，只要 1,000 美元即可进行交易。
交易平台上为每个货币对报出的两种不同价格，是该货币对可用的买入价和卖出价（或卖出价和买入价），这两种价格之间的差价称为价差。买入价 (Bid) 是左边的价格，这是您可以卖出给定货币对的价格，是所列出的两个价格中的较低者。卖出价 (Ask) 是右边的价格，它是您可以购买给定货币对的价格，是所列出的两个价格中的较高者。
已知点数百分比是交易市场中最小的数字价格走势。它通常是报价的最后一个小数字。由于大多数货币对的价格为 4 位小数（$ 0.0001），因此最小的变化将是小数点后的最后一位数。
点差是买入价和卖出价之间的差额。如果 USD/CAD 外汇报价提到 1.0180 / 83，则差价为 0.0003，通常表示为 “3点”。
杠杆率定义为交易中使用的资本金额与所需保证金的比率。换句话说，杠杆使您能够运用较小的存款（您的保证金）却能在交易控制更多的金额。例如，为了控制 100,000 美元的头寸，经纪人账户中维持 1,000 美元，此杠杆率比率为 100：1。
