A stop loss order is a trading strategy to minimize losses and lock in profits on any stock or ETF. Stop loss orders allow you to setup your exit strategy in case the trade goes wrong or make sure your position remains profitable if the market goes in the opposite direction.
Most brokerages let you setup a stop loss order in the Sell order type if you change the option from Market Trade to Stop Loss Order.
