Short-selling speculation is an operation mode of financial transactions, which is used in forex futures trading market. It is mainly the process that speculators predict that the price of foreign exchange futures will fall soon in the future, so in order not to lose their own profits, they sell first and then buy, hoping to sell at a high price and buy at a low price to hedge.

The futures market provides convenience for speculators. Unlike the spot market, you don't need to buy first and then sell. It can sell short and then buy at the right time. If speculators predict that the exchange rate price will be in a downward trend in the future, they can sell foreign exchange futures contracts first, and then buy foreign exchange futures with the same term at the lowered exchange rate when the exchange rate does fall to a certain extent, so as to hedge the short positions established before and profit from them.
