The Australian Dollar



The Australian dollar is a commodity-based currency and is currently the sixth most traded currency in the world currency market (behind the US dollar, the euro, the yen, the British pound and the Swiss franc).
It accounts for approximately 5% of the total volume of foreign exchange transactions (approximately 1.9 trillion dollars a day). Its popularity is due to the fact that there is little government intervention in the currency and a general view that Australia has a stable economy and government.

For much of its history, the Australian dollar was pegged to the British pound however, that changed in 1946, when it was pegged to the US dollar under the Bretton Woods system. When this system broke down in 1971, the AUD moved from a fixed peg to a moving peg to the US dollar. Then in September 1974, it moved to a moving peg against a basket of currencies called the TWI (trade weighted index) because of concerns about the fluctuations in the US dollar. This continued until December 1983, when the then Labour government under Prime Minister Bob Hawke and Treasurer Paul Keating “floated” the Australian dollar. The Australian dollar is now governed by its economy’s terms of trade. Should Australia’s commodity exports (minerals and farms) increase then the dollar increases. Should mineral prices falls or when domestic spending is greater than exports, then the dollar falls. The resulting volatility makes the Australian dollar an attractive vehicle for currency speculators and is the reason why it is one of the most traded currencies in the world despite the fact that Australia only comprises 2% of the global economic activity.

Over the last 23 years as a free floating currency, the Australian dollar has usually served as a proxy for gold due to the fact that Australia is the second largest producer of gold after South Africa. Fluctuations in the price of gold have seen corresponding rise and falls in the Australian dollar.

As well as its relationship with gold, like the Canadian and the New Zealand dollars, the Australian dollar is a commodity currency. According to the Australian Bureau of Agriculture and Resources Economic, commodity sales are expected to total AUD billion or about 55% of Australia’s exports, hence any movements in commodity prices will effect the Australian dollar. Expectation over the next few years is for a gradual easing of world economic growth, which should see the price of Australian commodities average lower and result in downward pressure on the Australian dollar especially in late 2006/2007. It should however be noted, that there is considerable uncertainty in predicting Australian dollar movements since it can be significantly influenced by a change in market sentiment. Since the floating of the Australian dollar in 1983, the currency has fluctuated in an average range of 10 cents a year.

Forex Forecast

Forex-Forecasting


This article provides insight into the two major methods of analysis used to forecast the behavior of the Forex market. Technical analysis and fundamental analysis differ greatly, but both can be useful forecast tools for the Forex trader. They have the same goal - to predict a price or movement. The technician studies the effect while the fundamentalist studies the cause of market movement. Many successful traders combine a mixture of both approaches for superior results.

Technical analysis

Technical analysis is a method of predicting price movements and future market trends by studying charts of past market action. Technical analysis is concerned with what has actually happened in the market, rather than what should happen and takes into account the price of instruments and the volume of trading, and creates charts from that data to use as the primary tool. One major advantage of technical analysis is that experienced analysts can follow many markets and market instruments simultaneously.

Technical analysis is built on three essential principles:

1. Market action discounts everything! This means that the actual price is a reflection of everything that is known to the market that could affect it, for example, supply and demand, political factors and market sentiment. However, the pure technical analyst is only concerned with price movements, not with the reasons for any changes.

2. Prices move in trends Technical analysis is used to identify patterns of market behavior that have long been recognized as significant. For many given patterns there is a high probability that they will produce the expected results. Also, there are recognized patterns that repeat themselves on a consistent basis.

3. History repeats itself Forex chart patterns have been recognized and categorized for over 100 years and the manner in which many patterns are repeated leads to the conclusion that human psychology changes little over time.

Forex charts are based on market action involving price. There are five categories in Forex technical analysis theory:

  • Indicators (oscillators, e.g.: Relative Strength Index (RSI)
  • Number theory (Fibonacci numbers, Gann numbers)
  • Waves (Elliott wave theory)
  • Gaps (high-low, open-closing)
  • Trends (following moving average).

Some major technical analysis tools are described below:

Relative Strength Index (RSI):
The RSI measures the ratio of up-moves to down-moves and normalizes the calculation so that the index is expressed in a range of 0-100. If the RSI is 70 or greater, then the instrument is assumed to be overbought (a situation in which prices have risen more than market expectations). An RSI of 30 or less is taken as a signal that the instrument may be oversold (a situation in which prices have fallen more than the market expectations).

Stochastic oscillator:
This is used to indicate overbought/oversold conditions on a scale of 0-100%. The indicator is based on the observation that in a strong up trend, period closing prices tend to concentrate in the higher part of the period's range. Conversely, as prices fall in a strong down trend, closing prices tend to be near to the extreme low of the period range. Stochastic calculations produce two lines, %K and %D that are used to indicate overbought/oversold areas of a chart. Divergence between the stochastic lines and the price action of the underlying instrument gives a powerful trading signal.

Moving Average Convergence Divergence (MACD):
This indicator involves plotting two momentum lines. The MACD line is the difference between two exponential moving averages and the signal or trigger line, which is an exponential moving average of the difference. If the MACD and trigger lines cross, then this is taken as a signal that a change in the trend is likely.

Number theory:
Fibonacci numbers: The Fibonacci number sequence (1,1,2,3,5,8,13,21,34...) is constructed by adding the first two numbers to arrive at the third. The ratio of any number to the next larger number is 62%, which is a popular Fibonacci retracement number. The inverse of 62%, which is 38%, is also used as a Fibonacci retracement number.

Gann numbers:
W.D. Gann was a stock and a commodity trader working in the '50s who reputedly made over million in the markets. He made his fortune using methods that he developed for trading instruments based on relationships between price movement and time, known as time/price equivalents. There is no easy explanation for Gann's methods, but in essence he used angles in charts to determine support and resistance areas and predict the times of future trend changes. He also used lines in charts to predict support and resistance areas.

Waves
Elliott wave theory: The Elliott wave theory is an approach to market analysis that is based on repetitive wave patterns and the Fibonacci number sequence. An ideal Elliott wave patterns shows a five-wave advance followed by a three-wave decline.

Gaps
Gaps are spaces left on the bar chart where no trading has taken place. An up gap is formed when the lowest price on a trading day is higher than the highest high of the previous day. A down gap is formed when the highest price of the day is lower than the lowest price of the prior day. An up gap is usually a sign of market strength, while a down gap is a sign of market weakness. A breakaway gap is a price gap that forms on the completion of an important price pattern. It usually signals the beginning of an important price move. A runaway gap is a price gap that usually occurs around the mid-point of an important market trend. For that reason, it is also called a measuring gap. An exhaustion gap is a price gap that occurs at the end of an important trend and signals that the trend is ending.

Trends
A trend refers to the direction of prices. Rising peaks and troughs constitute an up trend; falling peaks and troughs constitute a downtrend that determines the steepness of the current trend. The breaking of a trend line usually signals a trend reversal. Horizontal peaks and troughs characterize a trading range.

Moving averages are used to smooth price information in order to confirm trends and support and resistance levels. They are also useful in deciding on a trading strategy, particularly in futures trading or a market with a strong up or down trend.

The most common technical tools:

Coppock Curve is an investment tool used in technical analysis for predicting bear market lows.

DMI (Directional Movement Indicator) is a popular technical indicator used to determine whether or not a currency pair is trending.

Unlike the fundamental analyst, the technical analyst is not much concerned with any of the "bigger picture" factors affecting the market, but concentrates on the activity of that instrument's market.

Fundamental analysis

Fundamental analysis is a method of forecasting the future price movements of a financial instrument based on economic, political, environmental and other relevant factors and statistics that will affect the basic supply and demand of whatever underlies the financial instrument. In practice, many market players use technical analysis in conjunction with fundamental analysis to determine their trading strategy. Fundamental analysis focuses on what ought to happen in a market. Factors involved in price analysis: Supply and demand, seasonal cycles, weather and government policy.

Fundamental analysis is a macro or strategic assessment of where a currency should be trading based on any criteria but the movement of the currency's price itself. These criteria often include the economic condition of the country that the currency represents, monetary policy, and other "fundamental" elements.

Many profitable trades are made moments prior to or shortly after major economic announcements.

The history of forex Market

The History of the Forex Market


An overview into the historical evolution of the foreign exchange market

This article will follow the historical roots of the international currency trading from the days of the gold exchange, through the Bretton Woods Agreement, to its current setting.

The Gold exchange period and the Bretton Woods Agreement.

Prior to Bretton Woods, the gold exchange standard -- paramount between 1876 and World War I -- ruled over the international economic system. Under the gold exchange, currencies experienced a new era of stability because they were supported by the price of gold.

However, the gold exchange standard had a weakness of boom-bust patterns. As a country's economy strengthened, its imports would increase until the country ran down its gold reserves, which were required to support its currency. As a result, the money supply would diminish, interest rates escalate and economic activity slowed to the point of recession. Ultimately, prices of commodities would hit bottom, appearing attractive to other nations, who would rush in and amid a buying frenzy inject the economy with gold until it increased its money supply, driving down interest rates and restoring wealth into the economy. Such boom-bust patterns abounded throughout the gold standard until World War I temporarily discontinued trade flows and the free movement of gold.

The Bretton Woods Agreement, established in 1944, fixed national currencies against the dollar, and set the dollar at a rate of USD 35 per ounce of gold. The agreement was aimed at establishing international monetary steadiness by preventing money from taking flight across countries, and to curb speculation in the international currency market. Participating countries agreed to try to maintain the value of their currency within a narrow margin against the dollar and an equivalent rate of gold as needed. As a result, the dollar gained a premium position as a reference currency, reflecting the shift in global economic dominance from Europe to the USA. Countries were prohibited from devaluing their currency to benefit their foreign trade and were only allowed to devalue their currency by less than 10%. The great volume of international Forex trade led to massive movements of capital, which were generated by post-war construction during the 1950s, and this movement destabilized the foreign exchange rates established in Bretton Woods.

The year 1971 heralded the abandonment of the Bretton Woods in that the US dollar would no longer be exchangeable into gold. By 1973, the forces of supply and demand controlled major industrialized nations' currencies, which now floated more freely across nations. Prices were floated daily, with volumes, speed and price volatility all increasing throughout the 1970s, and new financial instruments, market deregulation and trade liberalization emerged.

The onset of computers and technology in the 1980s accelerated the pace of extending the market continuum for cross-border capital movements through Asian, European and American time zones. Transactions in foreign exchange increased intensively from nearly billion a day in the 1980s, to more than $1.9 trillion a day two decades later.

Exchange Rates

Exchange rates


Because currencies are traded in pairs and exchanged one against the other when traded, the rate at which they are exchanged is called the exchange rate. The majority of the currencies are traded against the US dollar (USD). The four next-most traded currencies are the Euro (EUR), the Japanese yen (JPY), the British pound sterling (GBP) and the Swiss franc (CHF). These five currencies make up the majority of the market and are called the major currencies or "the Majors". Some sources also include the Australian dollar (AUD) within the group of major currencies.

The first currency in the exchange pair is referred to as the base currency and the second currency as the counter term or quote currency. The counter term or quote currency is thus the numerator in the ratio, and the base currency is the denominator. The value of the base currency (denominator) is always 1. Therefore, the exchange rate tells a buyer how much of the counter term or quote currency must be paid to obtain one unit of the base currency. The exchange rate also tells a seller how much is received in the counter term or quote currency when selling one unit of the base currency. For example, an exchange rate for EUR/USD of 1.2083 specifies to the buyer of euros that 1.2083 USD must be paid to obtain 1 euro.

At any given point, time and place, if an investor buys any currency and immediately sells it - and no change in the exchange rate has occurred - the investor will lose money. The reason for this is that the bid price, which represents how much will be received in the counter or quote currency when selling one unit of the base currency, is always lower than the ask price, which represents how much must be paid in the counter or quote currency when buying one unit of the base currency. For instance, the EUR/USD bid/ask currency rates at your bank may be 1.2015/1.3015, representing a spread of 1000 pips (also called points, one pip = 0.0001), which is very high in comparison to the bid/ask currency rates that online Forex investors commonly encounter, such as 1.2015/1.2020, with a spread of 5 pips. In general, smaller spreads are better for Forex investors since even they require a smaller movement in exchange rates in order to profit from a trade.

Margin

Banks and/or online trading providers need collateral to ensure that the investor can pay in case of a loss. The collateral is called the margin and is also known as minimum security in Forex markets. In practice, it is a deposit to the trader's account that is intended to cover any currency trading losses in the future.

Margin enables private investors to trade in markets that have high minimum units of trading by allowing traders to hold a much larger position than their account value. Margin trading also enhances the rate of profit, but can also enhance the rate of loss if the investor makes the wrong decision.

Leveraged financing

Leveraged financing, i.e., the use of credit, such as a trade purchased on a margin, is very common in Forex. The loan/leveraged in the margined account is collateralized by your initial deposit. This may result in being able to control USD 100,000 for as little as USD 1,000.

There are three ways private investors can trade in Forex directly or indirectly:

  • The spot market
  • Forwards and futures
  • Options

A spot transaction

A spot transaction is a straightforward exchange of one currency for another. The spot rate is the current market price, also called the benchmark price. Spot transactions do not require immediate settlement, or payment "on the spot." The settlement date, or "value date," is the second business day after the "deal date" (or "trade date") on which the transaction is agreed to by the two traders. The two-day period provides time to confirm the agreement and arrange the clearing and necessary debiting and crediting of bank accounts in various international locations.

Forwards and Futures

Forwards make up about 46% of currency trading. A forward transaction is an agreement between two parties whereby one party buys a currency at a particular price by a certain date that is greater than two business days (a spot transaction).

A future contract is a forward contract with fixed currency amounts and maturity dates. They are traded on future exchanges and not through the interbank foreign exchange market.

Options

A currency option is similar to a futures contract in that it involves a fixed currency transaction at some future date in time. However the buyer of the option is only purchasing the right but not the obligation to purchase a fixed amount of currency at a fixed price by a certain date in future. The price is known as the premium and is lost if the buyer does not exercise the option.

Risks

Although Forex trading can lead to very profitable results, there are risks involved: exchange rate risks, interest rate risks, credit risks, and country risks. Approximately 80% of all currency transactions last a period of seven days or less, while more than 40% last fewer than two days. Given the extremely short lifespan of the typical trade, technical indicators heavily influence entry, exit and order placement decisions.

Forex Market Overview

An overview of the Forex market


The Forex market is a non-stop cash market where currencies of nations are traded, typically via brokers. Foreign currencies are constantly and simultaneously bought and sold across local and global markets and traders' investments increase or decrease in value based upon currency movements. Foreign exchange market conditions can change at any time in response to real-time events.

The main enticements of currency dealing to private investors and attractions for short-term Forex trading are:

  • 24-hour trading, 5 days a week with non-stop access to global Forex dealers.
  • An enormous liquid market making it easy to trade most currencies.
  • Volatile markets offering profit opportunities.
  • Standard instruments for controlling risk exposure.
  • The ability to profit in rising or falling markets.
  • Leveraged trading with low margin requirements.
  • Many options for zero commission trading.

Forex trading

The investor's goal in Forex trading is to profit from foreign currency movements. Forex trading or currency trading is always done in currency pairs. For example, the exchange rate of EUR/USD on Aug 26th, 2003 was 1.0857. This number is also referred to as a "Forex rate" or just "rate" for short. If the investor had bought 1000 euros on that date, he would have paid 1085.70 U.S. dollars. One year later, the Forex rate was 1.2083, which means that the value of the euro (the numerator of the EUR/USD ratio) increased in relation to the U.S. dollar. The investor could now sell the 1000 euros in order to receive 1208.30 dollars. Therefore, the investor would have USD 122.60 more than what he had started one year earlier. However, to know if the investor made a good investment, one needs to compare this investment option to alternative investments. At the very minimum, the return on investment (ROI) should be compared to the return on a "risk-free" investment. One example of a risk-free investment is long-term U.S. government bonds since there is practically no chance for a default, i.e. the U.S. government going bankrupt or being unable or unwilling to pay its debt obligation.

When trading currencies, trade only when you expect the currency you are buying to increase in value relative to the currency you are selling. If the currency you are buying does increase in value, you must sell back the other currency in order to lock in a profit. An open trade (also called an open position) is a trade in which a trader has bought or sold a particular currency pair and has not yet sold or bought back the equivalent amount to close the position.

However, it is estimated that anywhere from 70%-90% of the FX market is speculative. In other words, the person or institution that bought or sold the currency has no plan to actually take delivery of the currency in the end; rather, they were solely speculating on the movement of that particular currency.
