Forex Currency Pairs: Base and Quote Explained
Explain base and quote currency without guessing a trade direction.
Technical terms explained
Forex
The exchange of one currency for another. A Forex quote tells you how much of one currency buys one unit of another.
Currency pair
Two currencies quoted together: the first is the base, and the second is the quote currency.
Base currency
The first currency in a pair. Position size in base units describes how many units of that currency the position represents.
Quote currency
The second currency in a pair. The displayed rate is expressed in this currency per one unit of the base.
Forex compares one currency with another. In EUR/USD, EUR is the base and USD is the quote. A price of 1.0800 means one euro is quoted at 1.0800 US dollars. It is a ratio, not a company share price. Retail products can be leveraged contracts or CFDs rather than delivery of currency; the contract and jurisdiction matter.
Our operational rule
Read A/B as units of B for one unit of A.
Worked example
At EUR/USD 1.0900, one euro is quoted at 1.09 dollars. A rise from 1.0800 is a stronger euro relative to the dollar in that interval.
Counterexample
USD/JPY rising does not mean the yen strengthened: more yen are quoted per dollar.
Watch for this mistake
Treating every chart containing USD as having the same dollar direction.
Charts are synthetic. These classification rules are not evidence of profitability.
