There is no relationship between "buy first and then sell" and "first sell and then buy" in ICBC's personal foreign exchange trading business. They belong to two trading methods.

1. "Buy first and then sell" refers to going long in the financial market. It is a term for financial markets such as stocks, foreign exchange or futures: it is optimistic about the future rising prospects of stocks, foreign exchange or futures, and buy and hold to wait for the rise to make profits. Going long means going long. When bulls judge that the market is going up, they will immediately buy stocks. So going long means buying stocks, foreign exchange or futures, etc.

2. Sell first and then buy refers to short selling in the financial market. Short selling, also known as short selling, short selling (term in Hong Kong), short selling (term in Singapore, Malaysia), is an investment term for stocks, futures, etc., and an operating mode in stocks, futures and other markets. Contrary to the long position, in theory, one borrows the goods first, sells them, and then buys them back. Short selling refers to the expectation that the market will fall in the future, selling the stock in hand at the current price, and buying it after the market falls to obtain a profit from the price difference. Its trading behavior is characterized by selling first and then buying.
