In the Trading Detail List, the "Bid" and "Ask" columns show the "Buy" and "Sell" orders with the corresponding number of shares, respectively. The "Bid" column displays the limit buy orders, which are placed at a price lower than the current market price and are waiting to be executed. This column represents the outside market. The "Ask" column displays the limit sell orders, which are placed at a price higher than the current market price and are waiting to be executed. This column represents the inside market.

The term "active trading" refers to the buying and selling of stocks at the market price, regardless of whether the transaction is initiated by the buyer or seller. If the seller initiates the transaction, it is considered an active buy; if the buyer initiates it, it is considered an active sell.

Moreover, the term "current trading volume" refers to the number of shares traded at a given moment. The cumulative trading volume for the day is calculated by adding up all the individual trade volumes. The unit of measurement for trading volume is "hand,” which equals one trading unit. Therefore, the total trading volume of the stock is the total number of hands traded throughout the day.
