Foreign Exchange trading, also known as Forex or FX trading, has gained enormous popularity in recent years among layman individuals due to the growth of online brokers and the technological development of online trading platforms. With high liquidity, non-stop opening hours 5 days a week, and great opportunities, it is no wonder that the forex market is the world’s most traded market with a daily trading volume of $5 trillion USD.
When the USD is listed second in the pair, as in the EUR/USD or AUD/USD, the value of the pip is fixed. If you hold a 1000 micro lot, each pip movement is worth $0.10. If you hold a 10,000 mini lot then each pip is worth $1. If you hold a 100,000 standard lot then each pip move is worth $10. Pip values can vary by price and pair, so knowing the pip value of the pair you're trading is critical in determining position size and risk.
Trading currencies is the act of making predictions based on minuscule variations in the global economy and buying and selling accordingly. The exchange rate between two currencies is the rate at which one currency will be exchanged for another. Forex traders use available data to analyze currencies and countries like you would companies, thereby using economic forecasts to gain an idea of the currency's true value.
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.
There are actually three ways that institutions, corporations and individuals trade forex: the spot market, the forwards market and the futures market. The forex trading in the spot market always has been the largest market because it is the "underlying" real asset that the forwards and futures markets are based on. In the past, the futures market was the most popular venue for traders because it was available to individual investors for a longer period of time. However, with the advent of electronic trading and numerous forex brokers, the spot market has witnessed a huge surge in activity and now surpasses the futures market as the preferred trading market for individual investors and speculators. When people refer to the forex market, they usually are referring to the spot market. The forwards and futures markets tend to be more popular with companies that need to hedge their foreign exchange risks out to a specific date in the future.
