Direct forward foreign exchange trading: refers to trading directly in the forward foreign exchange market without corresponding trading in other markets. Banks usually don't quote the forward exchange rate in full, but use the difference between the forward exchange rate and the spot exchange rate, that is, the basis point quotation. The forward exchange rate may be higher or lower than the spot exchange rate.
Forward foreign exchange trading based on options: companies or enterprises usually don't know the exact date of their foreign exchange income in advance. Therefore, foreign exchange options can be traded with banks, which gives enterprises the right to execute forward contracts within a certain period after the trading date, such as 5-6 months.
