The main participants in this market are the larger international banks. Financial centers around the world function as anchors of trading between a wide range of multiple types of buyers and sellers around the clock, with the exception of weekends. Since currencies are always traded in pairs, the foreign exchange market does not set a currency's absolute value but rather determines its relative value by setting the market price of one currency if paid for with another. Ex: US$1 is worth X CAD, or CHF, or JPY, etc.
For instance, if you opened a long trade on the GBP/USD currency pair, and the pair increased in value, the price limit at which the trade should close (the stop loss) would climb alongside the price of the currency pair. If the value of the GBP/USD then started to fall, the trade would be closed as soon as it hit your stop loss, preserving any profits you had made beforehand.

Believe it or not, this question does come up from time to time, especially from anyone unfamiliar with the foreign exchange market. Unlike the futures markets, there is no central governing body nor any arbitration panels or clearing houses that control the foreign exchange market. All trade is conducted through credit agreements between individual members.

Spot for most currencies is two business days; the major exception is the U.S. dollar versus the Canadian dollar, which settles on the next business day. Other pairs settle in two business days. During periods that have multiple holidays, such as Easter or Christmas, spot transactions can take as long as six days to settle. The price is established on the trade date, but money is exchanged on the value date.

In the futures market, futures contracts are bought and sold based upon a standard size and settlement date on public commodities markets, such as the Chicago Mercantile Exchange. In the U.S., the National Futures Association regulates the futures market. Futures contracts have specific details, including the number of units being traded, delivery and settlement dates, and minimum price increments that cannot be customized. The exchange acts as a counterpart to the trader, providing clearance and settlement.
