In fact, the calculation between the forward exchange rate and the spot exchange rate does not need to consider the price method: the foreign exchange quotation is a two-way quotation, and both the buying price and the selling price of the benchmark currency are quoted, such as USD 1= RMB 6.5125/6.5135; The former is the price at which the offeror buys the benchmark currency, and the latter is the price at which the offeror sells the benchmark currency. Forward premium refers to the increase in the number of quoted currencies converted from the unit benchmark currency. In the forward quotation, if it is a point quotation, it depends on the quotation. If it is a forward premium, the quotation must be preceded by a decimal, followed by a large number, and the forward exchange rate is added before/after it, that is, the decimal is added to increase the large number. If it is a forward premium, it will be a big number in the quotation. Decimals come last, and the forward exchange rate decreases before and after, that is, decimals decrease large numbers, and large numbers decrease. Direct or indirect quotation is not necessary for calculation.

Direct bidding is a method of converting unit foreign currency into local currency. In two-way bidding, the former is the bid price (the concept of bid price is the exchange rate at which the offeror buys foreign currency) and the latter is the selling price. In indirect bidding, the former is the selling price and the latter is the buying price.
