In the global investment world, foreign exchange has become a new asset class. Through domestic commercial banks, customers can exchange freely convertible foreign exchanges or foreign currencies into another freely convertible foreign exchange or foreign currency transaction, which is called a foreign exchange real transaction. A firm offer means that in this type of transaction, customers cannot use financing methods similar to those in futures transactions, namely, funding from the bank after paying the margin to multiply the transaction amount several times.

The US dollar, the euro, the British pound, the Japanese yen, the Swiss franc, the Canadian dollar, the Australian dollar, and the Hong Kong dollar are the currencies available to domestic commercial banks for real foreign exchange transactions. The currencies are freely convertible. Actual foreign exchange transactions do not involve foreign currencies or foreign currencies that are not freely convertible. Consult the bank where you want to open an account to find out which currencies are convertible and which are not. When conducting real foreign exchange transactions, exchanging USD for another freely convertible foreign exchange or foreign currency is called Direct Trading, and exchanging USD for two other freely convertible foreign exchanges or foreign currencies is called Fork Trading.
