Order Types

• Market order
  A market order is an order to buy or sell at the current market price. For example, EUR/USD is currently trading at 1.2140. If you wanted to buy at this exact price, you would click buy and your trading platform would instantly execute a buy order at that exact price. If you ever shop on Amazon.com, it's (kinda) like using their 1-Click ordering. You like the current price, you click once and it's yours! The only difference is you are buying or selling one currency against another currency instead of buying Britney Spears CDs.
• Limit order
  A limit order is an order placed to buy or sell at a certain price. The order essentially contains two variables, price and duration. For example, EUR/USD is currently trading at 1.2050. You want to go long if the price reaches 1.2070. You can either sit in front of your monitor and wait for it to hit 1.2070 (at which point you would click a buy market order), or you can set a buy limit order at 1.2070 (then you could walk away from your computer to attend your ballroom dancing class). If the price goes up to 1.2070, your trading platform will automatically execute a buy order at that exact price. You specify the price at which you wish to buy/sell a certain currency pair and also specify how long you want the order to remain active (GTC or GFD).
• Stop-loss order
  A stop-loss order is a limit order linked to an open trade for the purpose of preventing additional losses if price goes against you. A stop-loss order remains in effect until the position is liquidated or you cancel the stop-loss order. For example, you went long (buy) EUR/USD at 1.2230. To limit your maximum loss, you set a stop-loss order at 1.2200. This means if you were dead wrong and EUR/USD drops to 1.2200 instead of moving up, your trading platform would automatically execute a sell order at 1.2200 and close out your position for a 30 pip loss (eww!). Stop-losses are extremely useful if you don't want to sit in front of your monitor all day worried that you will lose all your money. You can simply set a stop-loss order on any open positions so you won't miss your basket weaving class.
