It is not difficult to understand if you do a little more. Shorting is equivalent to borrowing and selling from others at a high price (for example, borrowing 100 shares, and you will have 1000 yuan after selling). The money is temporarily put in a brokerage firm, and then you buy the same amount of securities at a low price (for example, if you fall to 6 yuan to buy 100 shares, it means you bought it). It is equal to the process that you earned 400 yuan. Take rice as an analogy and do more: you are optimistic about the rising price of rice, buy or borrow rice to hoard it, and then sell it when the price of rice rises to earn the difference. Short selling: you are optimistic that the price of rice will decrease, borrow rice from the rice boss, then sell it for money, and then use the money to buy rice and return it to the rice boss to earn the difference.

Long futures refers to the operation that investors buy contract targets in anticipation of future market rise. Short futures refers to the operation that investors sell contracts in anticipation of future market decline and then buy them after the market decline to earn the difference. Futures are traded by margin, and margin trading is the standard contract of goods, not the goods themselves. The trading method is T+0, and the trading time is different: domestic futures trading time is 9: 00 am-11:00, afternoon 13:30- 15:00, and night trading time is 25: 00. 1. Go long: refers to the trading behavior of buying a certain number of stocks at the current price when the price is expected to rise in the future, and then selling them at a high price after the price rises, so as to earn the difference profit. It is characterized by the trading behavior of buying first and then selling. Going long is a mode of operation in the stock and futures markets. The general market can only do more, that is to say, buy first and then sell, and then sell when there is goods.

This model can only be profitable in the band of rising prices. That is, buy low before selling high. 2. Short selling: refers to selling stocks at the current price in anticipation of future price decline, and buying them after the market falls, thus making a profit. It is characterized by the trading behavior of selling first and then buying. Short selling is an important operation mode in stock and futures markets. This is the opposite of doing more. Theoretically, it is to borrow goods to sell first and then buy them back. Generally, the regular short-selling market has a neutral warehouse to provide a platform for borrowing goods. In fact, it is a bit like the credit transaction model in business. This model can profit in the wave band of falling prices, that is, borrowing goods at a high level and selling them, and then buying and returning them after falling. So buying is still low, selling is still high, but the operating procedures are reversed.
