In direct quotation, the foreign currency of a unit (1, 100, 1000, 10000) is used as the standard to calculate how many units of domestic currency should be paid, which is equivalent to calculating how much domestic currency should be paid for purchasing a unit of foreign currency, so it is also called the price payable method. Most countries in the world, including China, currently adopt direct quotation. Such as Japanese yen, Swiss franc and Canadian dollar.
Indirect pricing method is to calculate the foreign currency receivables of several units in the domestic currency of a unit (such as 1 unit). In the international foreign exchange market, euro, pound and Australian dollar are all indirectly priced.
