If you like to open a position you need to place an "entry" order. When an entry order executes, the position becomes "open" and it starts its life in the forex market. At any point in time, you can place an "exit" order to "close" the position. A position can be "long" (entry order is to buy and exit order is to sell an instrument) or "short" (entry order is to sell and exit order is to buy an instrument).

When trading forex you will often see a two-sided quote, consisting of a 'bid' and 'offer'. The 'bid' is the price at which you can sell the base currency (at the same time buying the counter currency). The 'ask' is the price at which you can buy the base currency (at the same time selling the counter currency).

At a point when you place your entry order, you need to define price level at which you want to buy or sell certain instrument. You also need to specify type of the order and quantity of the instrument you want to trade. There are 3 order types:
Market Order
Placing a market order means that you will buy at your broker's current "ask" (or "offer") price, or sell at your broker's current "bid" price, whatever that price currently is. For example, suppose you are buying EUR/USD. The current market, as quoted by your broker is 1.2934 / 1.2938. This means that your broker is willing to buy EUR/USD from you at 1.2934, and sell it to you at 1.2938.
Stop Order
Initiating a trade with a stop order means that you will only open a position if the market moves in the direction you are anticipating. For example, if USD/JPY is currently 108.72 and you believe it will move higher, you could place a stop order to buy at 108.82. This means that the order will only be executed if the market moves up to 108.82. The advantage is that if you are wrong and the market moves straight down, you will not have bought (because 108.82 will never have been reached). The disadvantage is that 108.82 is clearly a less attractive rate at which to buy than 108.72. Opening a position with a stop order is usually appropriate if you wish to trade only with strong market momentum in a particular direction.
Limit Order
A limit order is an order to buy below the current price, or sell above the current price. For example, if EUR/USD is trading at 1.2952 / 56 and you believe the market will rise, you could place a limit order to buy at 1.2945. If executed, this will give you a long position in EUR/USD at 1.2945, which is 11 pips better than if you had just bought EUR/USD with a market order. The disadvantage of the limit order is that if EUR/USD moves straight up from 1.2952 / 56, your limit at 1.2945 will never be filled and you will miss out on the profit opportunity even though your view on the direction of EUR/USD was correct. Opening a position with a limit order is usually appropriate if you believe that the market will remain in a range before moving in your anticipated direction, allowing the order to be filled first.
For both entry and exits orders you can specify price levels at which you want them to be executed. You have to specify entry levels when you place you entry order, while most brokers would allow you to specify exit levels at any time.
