A currency pair is a foreign exchange exchange exchange rate composed of two currencies, which is represented by two ISO codes plus a separator, such as GBP / USD. The first code represents "basic currency", The other is "secondary currency

exchange rate changes rapidly. The supply and demand of the market determines the value of money. In the foreign exchange market, the value of one currency is expressed by another currency. In a currency pair, the first currency is called "base currency", and the second currency is called "valuation currency" or "relative currency"

when you trade currency, you buy the base currency and sell the valuation currency. The exchange rate tells the buyer how much it costs to buy a unit of base currency. The order of currency pairs is usually the same, which is a common practice in the instry

for example, currency pair USD / JPY (USD is the base currency and JPY is the valuation currency). The order of currency pairs you see will not change. So, whether you buy or sell depends on the direction of the transaction. For example: USD / JPY - you can buy JPY with USD, or you can buy USD with JPY
