A stop loss order can help you to protect your account against unnecessarily large losses and manage your risks effectively. A stop loss automatically closes an open trade if the price moves against you and reaches the level you specified.
For example, if you have a long position of company XYZ at 109.58, you could set a stop loss at 107.00 – then, if the price falls to this level, the trade will be closed automatically, thereby capping your losses.
