The buying and selling transaction of ICBC's personal foreign exchange trading refers to the transaction in which investors first buy the transaction and then buy or sell part or all of the foreign exchange within the selling amount. In financial markets, it means doing more.

Do more is optimistic about the future rising prospects of stocks, foreign exchange or futures, and buy and hold for rising profits. Long is long. When bulls judge that the market is rising, they will buy stocks immediately, so long means buying stocks, foreign exchange or futures.
