A currency pair is a quotation of two different currencies, with the value of one currency being quoted against the other. Currency pairs are used to determine exchange rates in the foreign exchange market.

Currency Pair is a term used in the foreign exchange market to describe the two currencies that are being traded against each other. A currency pair is a quotation of the relative value of one currency unit against another currency unit. The currency pair indicates how much of the quote currency is needed to purchase one unit of the base currency.
The most common currency pairs are the major currency pairs, which include the US dollar (USD), the euro (EUR), the Japanese yen (JPY), the British pound (GBP), the Swiss franc (CHF), and the Canadian dollar (CAD). These currency pairs are the most actively traded and have the highest liquidity.
In addition to the major currency pairs, there are also minor currency pairs, which include the Australian dollar (AUD), the New Zealand dollar (NZD), the South African rand (ZAR), and the Singapore dollar (SGD). These currency pairs are less actively traded and have lower liquidity than the major currency pairs.
When trading currency pairs, traders must consider the exchange rate between the two currencies, the liquidity of the currency pair, and the volatility of the currency pair. Exchange rates are determined by the supply and demand of the two currencies, and the liquidity of the currency pair is determined by the amount of trading activity in the currency pair. Volatility is the amount of price movement in the currency pair, and it is determined by the amount of news and economic data that affects the currency pair.
When trading currency pairs, traders must also consider the spread, which is the difference between the bid and ask prices of the currency pair. The spread is the cost of trading the currency pair, and it is determined by the liquidity of the currency pair.

The most common currency pairs are the major currency pairs, which include the US dollar, the euro, the Japanese yen, the British pound, the Swiss franc, and the Canadian dollar.
