International futures is a commodity futures transaction with currency or other financial products as the subject matter. Among them, the two lines in international futures represent the fluctuation of currency exchange rate. Specifically, one line represents the buying trend of futures contracts, and the other line represents the selling trend.

First of all, the first line represents the buying price trend of futures contracts. Usually, the increase of the purchase price represents the increase of the market demand for the currency, and also means the increase of the exchange rate of the currency relative to other currencies. At this point, investors can consider buying futures contracts in this currency in the upward trend and selling them when the price reaches a certain ideal level, so as to gain income from them. Of course, investors also need to pay attention to market information and risk control when operating futures contracts.

Secondly, the second line represents the selling price trend of futures contracts. The rising selling price means that the money supply in the market decreases and the exchange rate also rises. Investors can consider selling futures contracts in the target currency at the right time in order to make a profit when the trend gradually rises.

Generally speaking, the two lines in international futures represent the relationship between exchange rate trend and buying and selling price, which provides investors with the basis for analyzing and forecasting market trend. Investors in international futures trading need to have enough knowledge of the market, and at the same time need to formulate scientific trading strategies in order to succeed in the ever-changing market.
