First, the traders should determine whether they want to buy or sell. If they want to enter a short order - whereby they will profit if the exchange rate falls - they simply need to click on the SELL rate. The opposite holds true for traders who enter buy orders: they can simply click on the BUY rate, and thus will profit if the exchange rate goes up. Example of How Buying / Selling Works

As with all markets, there are two prices for every currency pair. The difference between these two prices is the spread, or the cost of the trade. In this example, the spread is three pips. On the 10k position, a pip on the EUR/USD currency pair is worth $1.
