Limit Order

Definition

In financial markets, a limit order is an instruction to buy or sell a stock or other security at a specified price or better. This allows traders to have better control over the price at which they execute a trade. Limit orders can be placed as buy or sell orders: the price is guaranteed, but the execution of the order is not. A limit order will only be executed if the price meets the order's requirements.

Origin

The concept of limit orders originated in the early development of stock markets when traders needed a way to control transaction prices. With the rise of electronic trading platforms, limit orders became more common and easier to use, especially in the late 20th and early 21st centuries.

Categories and Features

Limit orders are primarily divided into buy limit orders and sell limit orders. A buy limit order requires purchasing securities at a specified price or lower, while a sell limit order requires selling securities at a specified price or higher. The main feature is price certainty, but the possibility of execution is uncertain.

Case Studies

A typical case involves trading Apple Inc. stock. Suppose an investor wants to buy Apple shares at $150; they can set a buy limit order. The order will be executed when the market price drops to $150 or lower. Another example is Tesla Inc. stock, where an investor might want to sell when the price reaches $700. They can set a sell limit order, which will only be executed when the market price reaches or exceeds $700.

Common Issues

Investors often misunderstand the execution guarantee of limit orders; in reality, limit orders only guarantee the price, not execution. Additionally, market volatility can lead to limit orders not being executed promptly, especially in fast-changing market environments.
