What is Stop Loss needed for?

Stop Loss is intended to minimize losses for specific orders when the price has started to move in an unprofitable direction. For Buy orders stop loss is set below the current market price. For Sell orders stop loss is set above the current market price. Stop Loss level is stored on the broker’s server so you don’t need to keep your PC turned on all the time — the function will be executed when the market price reaches your Stop Loss level.
