A stop order is a type of order that is placed to buy or sell an asset at a specified price. A buy stop order is placed above the current market price, while a sell stop order is placed below the current market price. When the market price reaches the specified stop price, the stop order is triggered, and the trade is executed at the best available price. Stop orders are commonly used in forex trading to help limit potential losses or to protect profits by automatically closing a position when the market moves against a trader’s position.
