In 1876, something called the gold exchange standard was implemented. Basically it said that all paper currency had to be backed by solid gold; the idea here was to stabilize world currencies by pegging them to the price of gold. It was a good idea in theory, but in reality it created boom-bust patterns which ultimately led to the demise of the gold standard.
For instance, the EUR/USD trading pair is the most traded currency pair in the world. Listed as EUR/USD makes the EUR the ‘base’ currency and USD the ‘counter.’ The price in the spot market next to this pair indicates the price of one Euro in USD. There will be a buy and a sell price, and the difference between the two is commonly referred to as the ‘spread.’
A growing portion of forex market participants is retail traders who invest through banks or brokers. The two primary types of brokers for retail traders are brokers and market makers.

HIGH RISK WARNING: Foreign exchange trading carries a high level of risk that may not be suitable for all investors. Leverage creates additional risk and loss exposure. Before you decide to trade foreign exchange, carefully consider your investment objectives, experience level, and risk tolerance. You could lose some or all of your initial investment; do not invest money that you cannot afford to lose. Educate yourself on the risks associated with foreign exchange trading, and seek advice from an independent financial or tax advisor if you have any questions.
In all cases, to make a meaningful description of trading hours worldwide, the opening and closing times at each location worldwide need to be presented with a common base reference time. In this article, for instance, the data is referenced to GMT. In other articles with a United States orientation, however, the common base reference time often used is Eastern Standard Time. It isn't wrong, but it's a little confusing for readers who don't distinguish between GMT and EST --something few persons other than forex traders and airline personnel need to deal with on a regular basis.
In this view, countries may develop unsustainable economic bubbles or otherwise mishandle their national economies, and foreign exchange speculators made the inevitable collapse happen sooner. A relatively quick collapse might even be preferable to continued economic mishandling, followed by an eventual, larger, collapse. Mahathir Mohamad and other critics of speculation are viewed as trying to deflect the blame from themselves for having caused the unsustainable economic conditions.
Foreign exchange fixing is the daily monetary exchange rate fixed by the national bank of each country. The idea is that central banks use the fixing time and exchange rate to evaluate the behavior of their currency. Fixing exchange rates reflect the real value of equilibrium in the market. Banks, dealers, and traders use fixing rates as a market trend indicator.
The foreign exchange market may be left unregulated by governments, with EXCHANGE RATES between currencies being determined by the free interplay of the forces of demand and supply (see FLOATING EXCHANGE RATE SYSTEM), or they may be subjected to support-buying and selling by countries’ CENTRAL BANKS in order to fix them at particular rates. See FIXED EXCHANGE RATE SYSTEM, TOBIN TAX.
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.
