Stock trading refers to buying and selling stocks upside down. The core content of stock trading is to obtain profits through the price difference between buying and selling stocks in the securities market.

The rise and fall of stock prices change with the fluctuation of the market. The fluctuation of stock price often shows the characteristics of differentiation, which stems from the concern of funds, and the relationship between them is like the relationship between water and ships. When the water overflows, the ship is high (the stock price rises when the capital flows in), and when the water runs out, the ship is shallow (the stock price falls when the capital flows out).

Trading rules:

There are also certain regulations on the number of stocks to be bought and sold: that is, the number of stocks entrusted to buy must be an integer multiple of one hand (each hand 100 shares), but the number of stocks entrusted to sell must not be an integer multiple of 100 shares. The buying or selling price must be within 10% of yesterday's closing price.

Price priority and time priority are implemented in stock trading: during the continuous bidding period, because many investors may buy and sell the same stock at the same time, the exchange has formulated the principle of "price priority and time priority". If the current price of a stock is 5.66 yuan, if investor A enters the purchase price of 5.66 yuan and investor B enters the purchase price of 5.67 yuan at the same time, investor B's declaration takes precedence over investor A's declaration ... If the purchase prices declared by everyone are the same, the transaction will be made first. The same is true for selling stocks. If the current price of a stock is 5.66 yuan, A enters the selling price of 5.66 yuan, and B also enters the selling price of 5.65 yuan, then B's declaration takes precedence over A's declaration. If both parties enter the same selling price, then whoever declares first will make a deal first. This situation is more prominent when the share price of a stock suddenly rises sharply or suddenly falls sharply.
