在外匯交易市場，貨幣成對交易。貨幣對的兩個組成幣種相互關聯、不可分割，貨幣對的兩個組成幣種在交易中互相兌換，一種貨幣的價值相對於另一種貨幣報價。例如歐元對美元為 EUR/USD，稱為貨幣對。報價 EUR / USD = 1.1500 意味著 1 歐元兌換 1.1500 美元。在這種情況下，EUR 是基礎貨幣，USD 是報價貨幣（計數貨幣）。這代表 1 歐元可兌換 1.15 美元；或是購買 100 歐元需要 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)
現貨外匯僅以特定金額進行交易，稱為口數，或基本上是您將買入或賣出的貨幣單位數量。例如，1 口 EUR/USD 等於 100,000 美元。目前所有外匯經紀商都允許客戶交易數量最小至 0.01 口（1 微型口數，相當於 1,000 美元），以及提供槓桿操作，這意味著您無需存入 100,000 美元，只要 1,000 美元即可進行交易。
交易平台上為每個貨幣對報出的兩種不同價格，是該貨幣對可用的買入價和賣出價（或賣出價和買入價），這兩種價格之間的差價稱為價差。買入價 (Bid) 是左邊的價格，這是您可以賣出給定貨幣對的價格，是所列出的兩個價格中的較低者。賣出價 (Ask) 是右邊的價格，它是您可以購買給定貨幣對的價格，是所列出的兩個價格中的較高者。
已知點數百分比是交易市場中最小的數字價格走勢。它通常是報價的最後一個小數位。由於大多數貨幣對的價格為 4 位小數（$ 0.0001），因此最小的變化將是小數點後的最後一位數。
點差是買入價和賣出價之間的差額。如果 USD/CAD 外匯報價提到 1.0180 / 83，則差價為 0.0003，通常表示為 “3點”。
槓桿率定義為交易中使用的資本金額與所需保證金的比率。換句話說，槓桿使您能夠運用較小的存款（您的保證金）卻能在交易控制更多的金額。例如，為了控制 100,000 美元的頭寸，經紀人帳戶中維持 1,000 美元，此槓桿率比率為 100：1。
