Who can give an example of "long" and "short" in futures?
Doing more is to expect the price to rise, buy more and order more, as long as the price rises, how much to earn, similar to stocks.
Shorting is the expected price drop. For example, the opening price of Douyi 1009 was 3,867 points, and now it has dropped to 3,837 points. If you are short, you will earn 30 points per ton and 300 points in one hand.
