Stop Order: Technical Overview

Extended Definition

A stop order (also known as a stop–loss order) is an order to buy or sell a security that becomes active only when a specified price level (the stop price) is reached. Once triggered, it converts to a market order. Stop orders are primarily used for risk management and to protect against adverse price movements. They can also be used to enter positions in trending markets. Unlike limit orders, stop orders guarantee execution after triggering but not price.
