Long futures refers to the behavior that investors think that the market price will rise, so they choose to buy contracts in order to earn the difference when selling contracts in the future. Specifically, Dragon buys futures contracts at a relatively low price, and then sells futures after the price rises, thus making a profit. This is a common investment method and one of the mainstream investment methods in the market at present.

The risk coefficient of long futures is directly proportional to the rate of return. Investors should pay attention to controlling risks when investing in futures to avoid falling into a loss situation due to excessive pursuit of high returns. When investors do long futures operations, they need to conduct sufficient market research to understand the specific investment targets and market trends, so as to make more informed investment decisions.

In addition, it should be noted that the futures market is volatile and risky, so investors need to keep a cool head when operating, and don't blindly follow the trend, otherwise the losses may be further expanded. For investors who lack experience in the futures market, it is suggested to make simulated investment first, and then make a firm offer after accumulating certain experience. In short, long futures is an effective investment method in the current market, which can not only get the return on investment, but also make an important contribution to the preservation and appreciation of investors' assets.
