Which of the following describes a limit order?

• A. An order executed only at the market price
• B. An order set to buy or sell once the price reaches a certain level
• C. An order to sell a security immediately
• D. An order that cannot be changed

Answer: (B)

A limit order is designed to buy or sell a security once the price reaches a specified level that the trader sets. This allows the trader to have control over the price at which the transaction is made, ensuring that they do not pay more than they are willing to buy for or sell for less than their desired price.

For example, if a trader places a limit order to buy a stock at $50, the order will only be executed if the stock price falls to $50 or lower. This is particularly valuable in day trading, where price movements can be rapid and controlling costs is critical to maintaining profitability.

The other provided options refer to different types of orders or characteristics that do not apply to limit orders, thereby reinforcing the correct understanding of what a limit order actually entails.
