Answer: ABC

Forex futures trading can generally be divided into foreign exchange futures hedging, foreign exchange futures speculation and arbitrage trading. Hedging of foreign exchange futures refers to trading in the futures market and the spot market in the same currency, in the same amount and in opposite directions. By establishing a break-even mechanism in the spot foreign exchange market and the forward foreign exchange market, its value will remain roughly unchanged, thus achieving hedging. Speculative trading of foreign exchange futures refers to the trading behavior of buying and selling foreign exchange futures contracts, profiting from the price changes of foreign exchange futures and taking advantage of the situation at the same time. Arbitrage trading of foreign exchange futures refers to the trading behavior that traders buy and sell two related foreign exchange futures contracts at the same time, and then hedge their contracts at the same time for a period of time in order to profit from the relative price changes of the two contracts.
