In plain English
What Currency pair means
Currencies are exchanged relative to other currencies rather than against a single universal price. In EUR/USD at 1.0800, EUR is the item being priced and USD is the currency used to state that price. Buying or selling the pair changes exposure to the relative value of both currencies, not to either currency in isolation.
Why it matters
The order of the two codes determines how to read price changes, calculate the position’s notional amount, and identify the currency in which profit and loss is initially measured. It also helps distinguish a spot-forex quotation from an FX futures contract, whose quote convention can differ from the spot-market convention.
Example
Suppose EUR/USD is quoted at 1.0800. This means €1 is worth $1.08. A trader buying €10,000 through this pair is, in simplified terms, buying €10,000 and selling the dollar equivalent: $10,800. If the rate later reaches 1.0850, one euro is worth five more U.S. cents than at entry.
Quick answers
Common questions
What does the slash in EUR/USD mean?+
The slash separates the base currency from the quote currency. EUR/USD means the number of U.S. dollars quoted for one euro. It does not mean that EUR and USD move independently within the same transaction.
Can the same two currencies be quoted in reverse order?+
Yes. EUR/USD and USD/EUR describe reciprocal exchange rates, although market convention generally uses one standard ordering for a given spot pair. A platform’s symbol should always be checked before placing an order.
