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).
As shareholders, they cannot directly enter the stock exchange to buy and sell stocks, but only through the members of the stock exchange, and the so-called members of the stock exchange are the usual securities operating institutions, that is, brokers. You can give orders to brokers to buy and sell stocks. This is called entrustment.
Entrustment must be based on transaction password or securities account. What needs to be pointed out here is that the legal entrustment in China's securities trading is the entrustment of price increase and decrease that takes effect on the same day. This means that the entrustment instructions issued by shareholders to securities firms must be clear: ① shareholder name ② fund card number ③ buy (or sell) ④ Shanghai (or Shenzhen) ⑤ stock name ⑧ stock code ⑧ entrusted price ⑧ entrusted quantity. And this entrustment is only valid on the day when the entrustment is issued. The abbreviation of stock is usually four or three Chinese characters, and the code of stock is six digits. The code and abbreviation of a stock must be consistent when it is entrusted for sale.
The entrustment method is as follows:
On-site computer entrustment of the business department, customers directly place orders in the computer of the business department, and the entrustment form is directly sent to the exchange seat through the special line. This kind of transaction is very safe and fast!
Internet computer entrustment, customers send entrustment instructions to the computer center of the business department through the public network at home, office or internet cafe, and the computer of the business department then transmits the instruction set to the place where the exchange is located. This method has certain network security risks and is easy to be attacked by hackers!
Fixed telephone entrustment, the customer sends the entrustment instruction directly to the computer center of the securities firm through the telephone entrustment system of the securities firm, and then to the seat of the exchange, which is safer! It's just complicated!
