A currency pair expresses the price of one currency in terms of another. When you see EUR/USD at 1.0850, you are seeing how many US dollars it costs to buy one euro. The first currency, called the base, is what you are buying or selling. The second, called the quote, is the currency in which the price is stated. Every forex trade is inherently a bet on the relative strength of two economies at once.
- Base currency
- The first currency in the pair, the one being bought or sold.
- Quote currency
- The second currency, the one in which the price is denominated.
- Exchange rate
- The price at which one unit of the base currency trades for units of the quote currency.
EUR/USD rises: the euro strengthens relative to the dollar.
EUR/USD falls: the euro weakens relative to the dollar.
A currency pair is always relative. When EUR/USD rises, it does not mean the euro is strong in absolute terms, only that it is stronger than the dollar at that moment. The dollar could be weakening while the euro stays flat. This relativity is why the desk always trades pairs in context of broader macro flows, never in isolation.
Understanding the pair as a relative trade, not a directional bet on one currency, is the foundation of how we structure every position.
