What does the bond trading instruction mean? Trading orders in the stock market refer to buying and selling orders in the stock market. Buying refers to the external market, which is a transaction in which an investor buys a stock and closes at the selling price of the selling investor. Counting all the current transactions, it is also called the outer disk. Usually, investors will observe the capital movement of stocks through the data of internal and external stocks. In domestic stock software, the red number indicates the external disk.

Buying and selling are similar in composition. When the newly submitted buy order price is the same as the current sell order price, the transaction can be made immediately. If the number of lots sold at this price does not reach the number of lots bought, then trade in the order of submitting the order, and keep the unsold part to form a new buy order.
