Common stocks(A-shares,B-shares),funds,bonds,bond repurchases,warrants,and other trading varieties approved by the China Securities Regulatory Commission.
Stocks are a type of securities issued by a limited liability company as evidence of the shares held by shareholders.
The Investment fund,referred to as the fund,is a collective securities investment method of sharing interests and risks,that is,through the issuance of fund units,the funds of investors are concentrated,which are managed and used by the fund manager,and are entrusted by the fund custodian to invest in financial instruments such as stocks and bonds.
Bonds are debt certificates issued by governments,financial institutions,industrial and commercial enterprises,and other institutions directly borrowing from society to raise funds,and promising to pay interest at a certain rate and repay the principal according to agreed conditions.
Bond repurchase transaction refers to the act of both buyers and sellers of bonds agreeing to engage in reverse trading at a certain price at a certain time in the future while completing the transaction.
A warrant is a type of certificate of rights that stipulates that the holder has the right(rather than the obligation)to purchase or sell the underlying securities from the issuer at the agreed price during a certain period,or to collect settlement differences through cash settlement or other means.
Every Monday to Friday,excluding national statutory holidays and closed days announced by the exchange.
From 9:15 to 9:25 on each trading day,it is the opening call auction time.
The continuous bidding time is from 9:30 to 11:30 and from 13:00 to 15:00 on each trading day of the Shanghai Stock Exchange.The continuous bidding time is from 9:30 to 11:30 and from 13:00 to 14:57 on each trading day of the Shenzhen Stock Exchange,and the closing call bidding time is from 14:57 to 15:00.

At present,the clearing and settlement system of Shanghai and Shenzhen A-shares adopts the"T+1"method,and investors cannot sell the stocks they buy on the same day.In terms of fund utilization,the funds obtained from selling stocks on the same day can be used to buy stocks,but the withdrawal of cash takes place the next day.
Reversal trading of securities refers to the complete or partial sale of securities purchased by investors after confirmation of transaction,before settlement and settlement.
Currently,B-shares are subject to"T+3"clearing and settlement and"T+1"swing trading,and can only be sold days after the stock is purchased.
Bonds and warrants are subject to"T+0"reverse trading,meaning that bonds and warrants purchased can be sold on the same day.
The difference between market price commission and limit price commission
Entrustment can buy and sell securities through two methods:limit price entrustment or market price entrustment.
Price limit commission refers to a client entrusting a securities company to buy and sell securities at a limited price,and the securities company must declare to buy securities at or below the limited price;Declare the sale of securities at a limited price or above the limit.
Market price commission refers to a client entrusting a securities company to buy and sell securities at market prices.
The principle of"price first,time first"bidding transaction
Securities bidding transactions are matched based on the principle of price priority and time priority.Among the two priorities,price takes precedence over time.
The principle of price priority is:buying orders at higher prices have priority over buying orders at lower prices,and selling orders at lower prices have priority over selling orders at higher prices.
The principle of time priority is:for both buyers and sellers with the same price,the first to declare shall have priority over the second to declare.The order is determined by the time when the trading host accepts the declaration.
Principles for determining transaction through collective bidding
The principle of transaction price for collective bidding is:
①The price that can achieve maximum trading volume;
②The price at which all buying orders above this price and selling orders below this price are traded;
③The price at which at least one buyer or seller with the same price has completed all transactions.
If two or more declared prices meet the above conditions,the declared price with the smallest outstanding volume shall be the transaction price;If there are still two or more declared prices that meet the above conditions for minimizing the outstanding volume,the intermediate price is the transaction price.
All transactions in collective bidding are executed at the same price.
Transactions that have not been completed during the collective bidding period will automatically enter continuous bidding.
Principles for determining bidding transactions
The principle of authenticity of the transaction price during continuous bidding is:
①The highest buying declared price is the same as the lowest selling declared price,and this price is the transaction price.
②If the buying declaration price is higher than the real-time minimum selling declaration price,the transaction price shall be the real-time minimum selling declaration price.
③If the selling declaration price is lower than the immediately disclosed highest buying declaration price,the transaction price shall be the immediately disclosed highest buying declaration price.
Relevant regulations on entrusted cancellation
After the commission,the outstanding portion can be revoked.The revoked or invalid entrustment shall be immediately returned to the corresponding funds or securities upon confirmation by the exchange host.
Please note that cancellation of orders is allowed during the 9:15 to 9:20 opening call bidding stage of the Shanghai Stock Exchange;9:Cancellation is not allowed between stages 20 and 9:25.Cancellation of orders is not allowed on the Shenzhen Stock Exchange from 9:20 to 9:25,and from 14:57 to 15:00.
In addition,the subscription of new shares cannot be cancelled.
Several Methods of Entrusted Trading
There are usually four ways:
①Fill out the buy or sell order form at the counter of the sales department and entrust it manually;
②Call the securities company's entrusted phone number for self-service telephone entrustment;
③Entrust through self-service keyboard terminals in the sales department;
④Entrust through online trading systems.
Entrusted transaction inquiry
You can conduct transaction inquiries through telephone entrustment,online transactions,and the query function of the self-service keyboard terminal system in the sales department.You can also print the delivery order at the sales department on the day after the entrustment.
What situations can lead to non transaction of the commission?
①Has the investor's commission entered the trading host of the stock exchange?If an investor fills in an invalid commission,it will be rejected by the exchange's trading host,or due to other reasons,the investor's commission does not enter the exchange's trading host,and the commission cannot be completed.
②When investors declare,the entrusted price may refer to the price displayed in the trading market at that time,but due to the time delay effect of market transmission,there is a time difference between the buying and selling declaration situation in the exchange trading host and the market display.When an investor's commission is reported to the exchange's trading host,the latest matching price may have changed,or it may result in the investor's commission being unable to be traded.
③During the declaration period,there was no declaration quantity that matched the investor's commission.
2.Price fluctuation limit
Limits on the fluctuation of securities varieties
The trading of stocks,funds and warrants shall be subject to price limits.
Formula for calculating price fluctuations
The formula for calculating the price of stocks and funds is:
The price of the increase or decrease is equal to the previous closing price*(1±the proportion of the increase or decrease),and the calculation result is rounded to the smallest unit of price change.
The increase price of the warrant=the closing price of the previous day of the warrant+(the increase price of the underlying security on the same day-the closing price of the underlying security on the previous day)*125%*the exercise ratio;
The decline price of the warrant=the closing price of the previous day of the warrant-(the closing price of the underlying security on the previous day-the decline price of the underlying security on the same day)*125%*the exercise ratio.When the calculation result is less than or equal to zero,the decline price of the warrant is zero.
The situation where there is no price limit on the first trading day
If one of the following situations occurs,there is no price increase or decrease limit on the first trading day:
①IPO stocks and Closed-end fund;
②Additional issuance of listed stocks;
③Stocks that have resumed listing after suspension of listing;
④Other situations recognized by the exchange.
Regulations of the Shanghai Stock Exchange on Collective Auction and Continuous Auction for Securities with No Price Limits on Purchase and Sale
The effective declared price during the stage of collective bidding shall comply with the following provisions:
①The declared price for stock trading shall not be higher than 900%of the previous closing price and shall not be lower than 50%of the previous closing price
②The maximum declared price for fund and debt trading shall not be higher than 150%of the previous closing price,and shall not be lower than 70%of the previous closing price.

①The declared price shall not be higher than 110%of the lowest selling price immediately disclosed and shall not be lower than 90%of the highest buying price immediately disclosed;At the same time,it shall not exceed 130%of the average of the highest and lowest bid prices mentioned above,and shall not be less than 70%of the average.
②If there is no declared buying price in the real-time disclosure,the lower of the lowest selling price or the latest transaction price in the real-time disclosure shall be considered as the highest buying price in the preceding item;
③If there is no declared selling price in the instant disclosure,the higher of the highest buying price or the latest transaction price in the instant disclosure shall be considered as the lowest selling price in the preceding paragraph.
If there is no trading on that day,the previous closing price shall be considered as the latest trading price.
