In the context of the foreign exchange market, traders liquidate their positions in various currencies to take up positions in safe-haven currencies, such as the US dollar. Sometimes, the choice of a safe haven currency is more of a choice based on prevailing sentiments rather than one of economic statistics. An example would be the financial crisis of 2008. The value of equities across the world fell while the US dollar strengthened (see Fig.1). This happened despite the strong focus of the crisis in the US.
Let's say that you sell the EUR/USD at 1.4022. If the EUR/USD falls, that means the euro is getting weaker and the U.S. dollar is getting stronger. You might have also noticed the quote price has four places to the right of the decimal. Currencies are quoted in pips. A pip is the unit you count profit or loss in. Most currency pairs, except Japanese yen pairs, are quoted to four decimal places. This fourth spot after the decimal point (at one 100th of a cent) is typically what traders watch to count "pips".
Forex, or the foreign exchange market (also called FX for short) is the marketplace where currencies are traded. At its simplest, a foreign exchange transaction might be, for example, when you transfer your local currency to a new one for an upcoming holiday. Across the market as a whole, an estimated 5.3 billion USD is traded every day between governments, banks, corporations, and speculators.
I have been trading equities for a few years and have just started reading about forex. This was the 12th book I read. It should have been the first! This is the only one so far that has taken the time to run through all details, it TEACHES you about the market, trading, techniques, money management and risk. The others I have read were Strategy books. Only after reading this can I understand what the others were trying to say.
An investor can profit from the difference between two interest rates in two different economies by buying the currency with the higher interest rate and shorting the currency with the lower interest rate. Prior to the 2008 financial crisis, it was very common to short the Japanese yen (JPY) and buy British pounds (GBP) because the interest rate differential was very large. This strategy is sometimes referred to as a "carry trade."
Similarly, if you wanted to purchase 3,000 USD with Euros, that would cost 2,570 EUR. With a leverage rate of 1:30, however, you could access 3,000 USD worth of the EUR/USD currency pair as a CFD with just 100 USD. The best part, however, is that the size of the potential profit a trader could make is the same as if they had invested in the asset outright. The risk here is that potential losses are magnified to the same extent as potential profits.
Forex (FX) is the marketplace where various national currencies are traded. The forex market is the largest, most liquid market in the world, with trillions of dollars changing hands every day. There is no centralized location, rather the forex market is an electronic network of banks, brokers, institutions, and individual traders (mostly trading through brokers or banks).
The foreign exchange market assists international trade and investments by enabling currency conversion. For example, it permits a business in the United States to import goods from European Union member states, especially Eurozone members, and pay Euros, even though its income is in United States dollars. It also supports direct speculation and evaluation relative to the value of currencies and the carry trade speculation, based on the differential interest rate between two currencies.
In developed nations, the state control of the foreign exchange trading ended in 1973 when complete floating and relatively free market conditions of modern times began. Other sources claim that the first time a currency pair was traded by U.S. retail customers was during 1982, with additional currency pairs becoming available by the next year.
For trading purposes, the first currency listed in the pair is always the directional currency on a forex price chart. If you pull up a chart of the EUR/USD, and the price is moving higher, it means the EUR is moving higher relative to the USD. If the price on the chart is falling, then the EUR is declining in value relative to the USD. The attached chart shows this.
Many new traders choose not to close a trade because the market is still moving in the direction they want it to, only to then lose all of their gains when the direction suddenly changes. If your trade hits your predetermined target, close it and enjoy your winnings. If the market moves in the opposite direction, close the trade or set a stop loss so it will close automatically.
Factors like interest rates, trade flows, tourism, economic strength, and geopolitical risk affect supply and demand for currencies, which creates daily volatility in the forex markets. An opportunity exists to profit from changes that may increase or reduce one currency's value compared to another. A forecast that one currency will weaken is essentially the same as assuming that the other currency in the pair will strengthen because currencies are traded as pairs.
