Spot foreign exchange trading is the most common trading form in the foreign exchange market. Its trading volume ranks first among all kinds of foreign exchange transactions. So some concepts related to it must be clarified. (Point), referred to as point, refers to the basic unit of exchange rate. Generally speaking, a basic point is one ten thousandth of a currency unit, that is, the fourth unit number after the decimal point of the exchange rate (0,0001). Because of the large denomination, the basis points of a few currencies are somewhat different. For example, the price change of Japanese yen is mainly in two decimal places, so its base point is 0.0 1 unit currency.
