"Short selling" in futures and "selling" in stocks are not the same concept, so don't confuse them.
Other trading methods are basically similar to stocks, but remember, if you are not hedging or have a large amount of money, don't make long or overnight orders (that is, don't hold positions overnight), because the external market is night trading. If there are unexpected news or unexpected events that are not conducive to your position, you will be at risk of exploding your position. That is to say, once the funds in your account are opened the next morning, you will suffer considerable losses or even go up in smoke. What's more, you will still owe money to the futures company!
High position short position
The so-called high short position is to sell when the price is relatively high and buy it back when the price falls. For example, the price of corn in the market is 1.5 a catty, and the futures price has risen to 100 a catty, so even if the price is high, you can consider selling it first.
