STOP ORDERS IN FOREX

Stop Orders are orders placed to enter or exit the market at a desired specific price. When you buy above the market, it is a Stop Order. When you sell below the market, it is a Stop Order. Stop Orders turn into Market Orders when the market trades at that price. Stop Orders as well as Market Orders are subject to slippage, while Limit Orders are not.
The majority of Stop Orders are used as protective Stop Loss Orders. It is the order you place with your entry order to insure an exit when the market goes against you. A good trader never trades without a protective Stop Loss Order. They are orders executed to get you out of the market when your trade has gone against you.
