VIDEO GAME REVIEWS:BEST OF 2008

Video game reviews: The best of 2008
Next week, gaming's biggest names will gather in Los Angeles for the 2008 Electronic Entertainment Expo (E3). It is the industry's premier showcase, where these superpowers will lay out their plans for the coming year and beyond. This Christmas will be critical for Nintendo, Microsoft and Sony as they hope to capitalise on a record breaking 2007. Last year's holiday period saw an incredible amount of top quality games released, but, unusually, it wasn't a trend that wavered as we moved into 2008.

Here, we pick up the 25 best games released in the last 6 months, before we once again begin to look forward to a bumper fourth quarter
25. Lost Odyssey (Xbox 360) Buy Lost Odyssey
Produced by Hironobu Sakaguchi, famed creator of the Final Fantasy series, Lost Odyssey is a sprawling, epic Japanese RPG. The game follows the tragic tale of Kaim Argonar, an immortal who has suffered life for a thousand years. Achingly beautiful, Lost Odyssey features traditional turn-based battles, but keeps things fresh with its engaging 'ring' system.

Also worthy of mention are the wonderful short stories penned by famous Japanese author Kiyoshi Shigematsu unlocked throughout the game; they paint a truly heart-breaking picture of Kaim's thousand year struggle with the curse of immortality.

FINAL YEAR PROJECT GETTING STARTED

The most difficult part of writing a Final Year Project (FYP) is often 'where to begin'. Here are a few tips to help you..

  • Think of a topic in your course that you have found particularly interesting. This may be a chapter or an issue in a book associated with your course. Or it could be the wole or part of an assignment that you wished to explore in more detail. On the other hand, in the social sciences and business, there may be an issue in the news (read a good newspaper regularly!) that excites your attention.
  • Make sure that the issue is researchable. This means that there must be a literature base either in textbooks or periodicals. The literature base needs to be academic and not journalistic to add to the credibility of your FYP
  • Be prepared to spend several hours in an academic library to help you search out good sources on your intended topic. Remember the Internet is good for some things but there is no 'quality control' so some of the articles you get might be too emphemeral or journalistic for an academic piece of work.
  • It is probably better to think of the whole of your final year project as essentially answering a question rather than researching a field.
  • Make a plan of the chapters. Your plan is likely to look like this:
    • Introduction
    • Literature review
    • Updating/applying new research
    • Recent developments
    • Case study/small survey
    • Conclusion
  • Think of reading around the subject and writing your initial plan as a process in which each activity reinforces the other in a circular process. Do some initial research, then make a tentative plan, then do more reading to 'flesh out' the plan, then revise the plan and so on. Your plan only needs to be tentative at this stage - in all probability it will actually get revised as you make progress through your project. You should provide your tutor with a copy of your plan on your first substantive meeting.
  • Do not think you have to do all of the reading around the topic before you start to write. Read or research sufficiently to write the first chapter (literature review) and then start writing a first draft
  • When you start writing, set yourself a target - say 500-1000 words per day and then you will feel that you are making progress

FOREX

FOREX POST1:
The foreign exchange (currency or forex or FX) market exists wherever one currency is traded for another. It is the largest and most liquid financial market in the world, and includes trading between large banks, central banks, currency speculators, multinational corporations, governments, and other financial markets and institutions. The average daily trade in the global forex and related markets currently is almost US$ 4 trillion.[1]
Market size and liquidity
The foreign exchange market is unique because of
its trading volumes,
the extreme
liquidity of the market,
the large number of, and variety of, traders in the market,
its geographical dispersion,
its long trading hours: 24 hours a day except on weekends (from 5pm EST on Sunday until 4pm EST Friday),
the variety of factors that affect
exchange rates.
the low margins of profit compared with other markets of fixed income (but profits can be high due to very large trading volumes)
the use of
leverage

Main foreign exchange market turnover, 1988 - 2007, measured in billions of USD.
As such, it has been referred to as the market closest to the ideal
perfect competition, notwithstanding market manipulation by central banks. According to the BIS,[1] average daily turnover in global foreign exchange markets is estimated at $3.98 trillion. Trading in the world's main financial markets accounted for $3.21 trillion of this.
This $3.21 trillion in main foreign exchange market turnover was broken down as follows:
$1,005 billion in
spot transactions
$362 billion in
outright forwards
$1,714 billion in
forex swaps
$129 billion estimated gaps in reporting
Of the $3.98 trillion daily global turnover, trading in
London accounted for around $1.36 trillion, or 34.1% of the total, making London by far the global center for foreign exchange. In second and third places respectively, trading in New York accounted for 16.6%, and Tokyo accounted for 6.0%.
In addition to "traditional" turnover, $2.1 trillion was traded in
derivatives.
Exchange-traded forex
futures contracts were introduced in 1972 at the Chicago Mercantile Exchange and are actively traded relative to most other futures contracts. Forex futures volume has grown rapidly in recent years, and accounts for about 7% of the total foreign exchange market volume, according to The Wall Street Journal Europe (5/5/06, p. 20).

Foreign exchange trading increased by 38% between April 2005 and April 2006 and has more than doubled since 2001. This is largely due to the growing importance of foreign exchange as an asset class and an increase in fund management assets, particularly of hedge funds and pension funds. The diverse selection of execution venues such as
internet trading platforms offered by companies such as First Prudential Markets and Saxo Bank have made it easier for retail traders to trade in the foreign exchange market.
Because foreign exchange is an OTC market where brokers/dealers negotiate directly with one another, there is no central exchange or clearing house. The biggest geographic trading centre is the UK, primarily London, which according to IFSL estimates has increased its share of global turnover in traditional transactions from 31.3% in April 2004 to 34.1% in April 2007. RPP
The ten most active traders account for almost 73% of trading volume, according to The
Wall Street Journal Europe, (2/9/06 p. 20). These large international banks continually provide the market with both bid (buy) and ask (sell) prices. The bid/ask spread is the difference between the price at which a bank or market maker will sell ("ask", or "offer") and the price at which a market-maker will buy ("bid") from a wholesale customer. This spread is minimal for actively traded pairs of currencies, usually 0–3 pips. For example, the bid/ask quote of EUR/USD might be 1.2200/1.2203 on a retail broker. Minimum trading size for most deals is usually 100,000 units of currency, which is a standard "lot".
These spreads might not apply to retail customers at banks, which will routinely mark up the difference to say 1.2100 / 1.2300 for transfers, or say 1.2000 / 1.2400 for banknotes or travelers' checks. Spot prices at market makers vary, but on EUR/USD are usually no more than 3 pips wide (i.e. 0.0003). Competition is greatly increased with larger transactions, and pip spreads shrink on the major pairs to as little as 1 to 2 pips.

Unlike a stock market, where all participants have access to the same prices, the forex market is divided into levels of access. At the top is the inter-bank market, which is made up of the largest investment banking firms. Within the inter-bank market, spreads, which are the difference between the bid and ask prices, are razor sharp and usually unavailable, and not known to players outside the inner circle. As you descend the levels of access, the difference between the bid and ask prices widens (from 0-1 pip to 1-2 pips for some currencies such as the EUR). This is due to volume. If a trader can guarantee large numbers of transactions for large amounts, they can demand a smaller difference between the bid and ask price, which is referred to as a better spread. The levels of access that make up the forex market are determined by the size of the “line” (the amount of money with which they are trading). The top-tier inter-bank market accounts for 53% of all transactions. After that there are usually smaller investment banks, followed by large multi-national corporations (which need to hedge risk and pay employees in different countries), large hedge funds, and even some of the retail forex market makers. According to Galati and Melvin, “Pension funds, insurance companies, mutual funds, and other institutional investors have played an increasingly important role in financial markets in general, and in FX markets in particular, since the early 2000s.” (2004) In addition, he notes, “Hedge funds have grown markedly over the 2001–2004 period in terms of both number and overall size” Central banks also participate in the forex market to align currencies to their economic needs.

Banks
The interbank market caters for both the majority of commercial turnover and large amounts of speculative trading every day. A large bank may trade billions of dollars daily. Some of this trading is undertaken on behalf of customers, but much is conducted by proprietary desks, trading for the bank's own account.
Until recently, foreign exchange brokers did large amounts of business, facilitating interbank trading and matching anonymous counterparts for small fees. Today, however, much of this business has moved on to more efficient electronic systems. The broker squawk box lets traders listen in on ongoing interbank trading and is heard in most
trading rooms, but turnover is noticeably smaller than just a few years ago.

Commercial companies
An important part of this market comes from the financial activities of companies seeking foreign exchange to pay for goods or services. Commercial companies often trade fairly small amounts compared to those of banks or speculators, and their trades often have little short term impact on market rates. Nevertheless, trade flows are an important factor in the long-term direction of a currency's exchange rate. Some multinational companies can have an unpredictable impact when very large positions are covered due to exposures that are not widely known by other market participants.

Central banks
National central banks play an important role in the foreign exchange markets. They try to control the
money supply, inflation, and/or interest rates and often have official or unofficial target rates for their currencies. They can use their often substantial foreign exchange reserves to stabilize the market. Milton Friedman argued that the best stabilization strategy would be for central banks to buy when the exchange rate is too low, and to sell when the rate is too high — that is, to trade for a profit based on their more precise information. Nevertheless, the effectiveness of central bank "stabilizing speculation" is doubtful because central banks do not go bankrupt if they make large losses, like other traders would, and there is no convincing evidence that they do make a profit trading.
The mere expectation or rumor of central bank
intervention might be enough to stabilize a currency, but aggressive intervention might be used several times each year in countries with a dirty float currency regime. Central banks do not always achieve their objectives. The combined resources of the market can easily overwhelm any central bank.Several scenarios of this nature were seen in the 1992–93 ERM collapse, and in more recent times in Southeast Asia.

Hedge funds
Hedge funds have gained a reputation for aggressive currency speculation since 1996. They control billions of dollars of equity and may borrow billions more, and thus may overwhelm intervention by central banks to support almost any currency, if the economic fundamentals are in the hedge funds' favor.

Investment management firms
Investment management firms (who typically manage large accounts on behalf of customers such as pension funds and endowments) use the foreign exchange market to facilitate transactions in foreign securities. For example, an investment manager with an international equity portfolio will need to buy and sell foreign currencies in the spot market in order to pay for purchases of foreign equities. Since the forex transactions are secondary to the actual investment decision, they are not seen as speculative or aimed at profit-maximization.
Some investment management firms also have more speculative specialist
currency overlay operations, which manage clients' currency exposures with the aim of generating profits as well as limiting risk. Whilst the number of this type of specialist firms is quite small, many have a large value of assets under management (AUM), and hence can generate large trades.

Retail forex brokers
There are two types of retail broker: brokers offering speculative trading.
Retail forex brokers or market makers handle a minute fraction of the total volume of the foreign exchange market. Retail traders (individuals) are a small fraction of this market and may only participate indirectly through brokers or banks, and might be subject to forex scams.

Other
Non-bank foreign exchange companies offer currency exchange and international payments to private individuals and companies. These are also known as Foreign Exchange Brokers but are distinct from Forex Brokers as they do not offer speculative trading but currency exchange with payments. i.e. there is usually a physical delivery of currency to a bank account.
It is estimated that in the UK, 14% of currency transfers/payments are made via Foreign Exchange Companies
. These companies' selling point is usually that they will offer better exchange rates or cheaper payments than the customer's bank. These companies differ from Money Transfer/Remittance Companies in that they generally offer higher-value services.
Money Transfer/Remittance Companies perform high-volume low-value transfers generally by economic migrants back to their home country. In 2007, the Aite Group estimated that there were $369 billion of remittances (an increase of 8% on the previous year). The four largest markets (India, China, Mexico and the Philippines) receive $95 billion. The largest and best known provider is Western Union with 345,000 agents globally.

There is no unified or centrally cleared market for the majority of FX trades, and there is very little cross-border regulation. Due to the
over-the-counter (OTC) nature of currency markets, there are rather a number of interconnected marketplaces, where different currencies instruments are traded. This implies that there is not a single exchange rate but rather a number of different rates (prices), depending on what bank or market maker is trading, and where it is. In practice the rates are often very close, otherwise they could be exploited by arbitrageurs instantaneously. Due to London's dominance in the market, a particular currency's quoted price is usually the London market price. A joint venture of the Chicago Mercantile Exchange and Reuters, called FxMarketSpace opened in 2007 and aspires to the role of a central market clearing mechanism.
The main trading center is
London, but New York, Tokyo, Hong Kong and Singapore are all important centers as well. Banks throughout the world participate. Currency trading happens continuously throughout the day; as the Asian trading session ends, the European session begins, followed by the North American session and then back to the Asian session, excluding weekends.
There is little or no '
inside information' in the foreign exchange markets. Exchange rate fluctuations are usually caused by actual monetary flows as well as by expectations of changes in monetary flows caused by changes in GDP growth, inflation, interest rates, budget and trade deficits or surpluses, large cross-border M&A deals and other macroeconomic conditions. Major news is released publicly, often on scheduled dates, so many people have access to the same news at the same time. However, the large banks have an important advantage; they can see their customers' order flow.
Currencies are traded against one another. Each pair of currencies thus constitutes an individual product and is traditionally noted XXX/YYY, where YYY is the
ISO 4217 international three-letter code of the currency into which the price of one unit of XXX is expressed (called base currency). For instance, EUR/USD is the price of the euro expressed in US dollars, as in 1 euro = 1.5465 dollar. Out of convention, the first currency in the pair, the base currency, was the stronger currency at the creation of the pair. The second currency, counter currency, was the weaker currency at the creation of the pair.
The factors affecting XXX will affect both XXX/YYY and XXX/ZZZ. This causes positive currency
correlation between XXX/YYY and XXX/ZZZ.
On the
spot market, according to the BIS study, the most heavily traded products were:
EUR/USD: 27 %
USD/JPY: 13 %
GBP/USD (also called
sterling or cable): 12 %
and the US currency was involved in 86.3% of transactions, followed by the euro (37.0%), the yen (16.5%), and sterling (15.0%) (see
table). Note that volume percentages should add up to 200%: 100% for all the sellers and 100% for all the buyers.
Trading in the euro has grown considerably since the currency's creation in January
1999, and how long the foreign exchange market will remain dollar-centered is open to debate. Until recently, trading the euro versus a non-European currency ZZZ would have usually involved two trades: EUR/USD and USD/ZZZ. The exception to this is EUR/JPY, which is an established traded currency pair in the interbank spot market. As the dollar's value has eroded during 2008, interest in using the euro as reference currency for prices in commodities (such as oil), as well as a larger component of foreign reserves by banks, has increased dramatically. Transactions in the currencies of commodity-producing countries, such as AUD, NZD, CAD, have also increased.

Factors affecting currency trading

Exchange rates
Although exchange rates are affected by many factors, in the end, currency prices are a result of supply and demand forces. The world's currency markets can be viewed as a huge melting pot: in a large and ever-changing mix of current events,
supply and demand factors are constantly shifting, and the price of one currency in relation to another shifts accordingly. No other market encompasses (and distills) as much of what is going on in the world at any given time as foreign exchange.
Supply and demand for any given currency, and thus its value, are not influenced by any single element, but rather by several. These elements generally fall into three categories:
economic factors, political conditions and market psychology.

Economic factors
These include economic policy, disseminated by government agencies and
central banks, economic conditions, generally revealed through economic reports, and other economic indicators.
Economic policy comprises government
fiscal policy (budget/spending practices) and monetary policy (the means by which a government's central bank influences the supply and "cost" of money, which is reflected by the level of interest rates).
Economic conditions include:
Government budget deficits or surpluses: The market usually reacts negatively to widening government
budget deficits, and positively to narrowing budget deficits. The impact is reflected in the value of a country's currency.
Balance of trade levels and trends: The trade flow between countries illustrates the demand for goods and services, which in turn indicates demand for a country's currency to conduct trade. Surpluses and deficits in trade of goods and services reflect the competitiveness of a nation's economy. For example,
trade deficits may have a negative impact on a nation's currency.
Inflation levels and trends: Typically, a currency will lose value if there is a high level of
inflation in the country or if inflation levels are perceived to be rising. This is because inflation erodes purchasing power, thus demand, for that particular currency. However, a currency may sometimes strengthen when inflation rises because of expectations that the central bank will raise short-term interest rates to combat rising inflation.
Economic growth and health: Reports such as gross domestic product (
GDP), employment levels, retail sales, capacity utilization and others, detail the levels of a country's economic growth and health. Generally, the more healthy and robust a country's economy, the better its currency will perform, and the more demand for it there will be.

Political conditions
Internal, regional, and international
political conditions and events can have a profound effect on currency markets.
For instance, political upheaval and instability can have a negative impact on a nation's economy. The rise of a political faction that is perceived to be fiscally responsible can have the opposite effect. Also, events in one country in a region may spur positive or negative interest in a neighboring country and, in the process, affect its currency.

Market psychology
Market psychology and trader perceptions influence the foreign exchange market in a variety of ways:
Flights to quality: Unsettling international events can lead to a "
flight to quality," with investors seeking a "safe haven". There will be a greater demand, thus a higher price, for currencies perceived as stronger over their relatively weaker counterparts. The Swiss franc has been a traditional safe haven during times of political or economic uncertainty.
Long-term trends: Currency markets often move in visible long-term trends. Although currencies do not have an annual growing season like physical commodities, business cycles do make themselves felt. Cycle analysis looks at longer-term price trends that may rise from economic or political trends.
"Buy the rumor, sell the fact:" This market truism can apply to many currency situations. It is the tendency for the price of a currency to reflect the impact of a particular action before it occurs and, when the anticipated event comes to pass, react in exactly the opposite direction. This may also be referred to as a market being "oversold" or "overbought". To buy the rumor or sell the fact can also be an example of the cognitive bias known as anchoring, when investors focus too much on the relevance of outside events to currency prices.
Economic numbers: While
economic numbers can certainly reflect economic policy, some reports and numbers take on a talisman-like effect: the number itself becomes important to market psychology and may have an immediate impact on short-term market moves. "What to watch" can change over time. In recent years, for example, money supply, employment, trade balance figures and inflation numbers have all taken turns in the spotlight.
Technical trading considerations: As in other markets, the accumulated price movements in a currency pair such as EUR/USD can form apparent patterns that traders may attempt to use. Many traders study price charts in order to identify such patterns.

Algorithmic trading in forex
Electronic trading is growing in the FX market, and algorithmic trading is becoming much more common. According to financial consultancy Celent estimates, by 2008 up to 25% of all trades by volume will be executed using algorithm, up from about 18% in 2005.[citation needed]

Financial instruments

Spot
A
spot transaction is a two-day delivery transaction (except in the case of the Canadian dollar, which settles the next day), as opposed to the futures contracts, which are usually three months. This trade represents a “direct exchange” between two currencies, has the shortest time frame, involves cash rather than a contract; and interest is not included in the agreed-upon transaction. The data for this study come from the spot market. Spot has the largest share by volume in FX transactions among all instruments.

Forward
See also:
forward contract
One way to deal with the Forex risk is to engage in a
forward transaction. In this transaction, money does not actually change hands until some agreed upon future date. A buyer and seller agree on an exchange rate for any date in the future, and the transaction occurs on that date, regardless of what the market rates are then. The duration of the trade can be a few days, months or years.

Future
Main article:
Currency future
Foreign currency futures are forward transactions with standard contract sizes and maturity dates — for example, 500,000 British pounds for next November at an agreed rate. Futures are standardized and are usually traded on an exchange created for this purpose. The average contract length is roughly 3 months. Futures contracts are usually inclusive of any interest amounts.

Swap
Main article:
Forex swap
The most common type of forward transaction is the currency swap. In a swap, two parties exchange currencies for a certain length of time and agree to reverse the transaction at a later date. These are not standardized contracts and are not traded through an exchange.

Option
Main article:
Foreign exchange option
A foreign exchange option (commonly shortened to just FX option) is a derivative where the owner has the right but not the obligation to exchange money denominated in one currency into another currency at a pre-agreed exchange rate on a specified date. The FX options market is the deepest, largest and most liquid market for options of any kind in the world.

Exchange Traded Fund
Main article:
Exchange-traded fund
Exchange-traded funds (or ETFs) are Open Ended investment companies that can be traded at any time throughout the course of the day. Typically, ETFs try to replicate a stock market index such as the S&P 500 (e.g. SPY), but recently they are now replicating investments in the currency markets with the ETF increasing in value when the US Dollar weakness versus a specific currency, such as the Euro. Certain of these funds track the price movements of world currencies versus the US Dollar, and increase in value directly counter to the US Dollar, allowing for speculation in the US Dollar for US and US Dollar denominated investors and speculators.

Speculation
Controversy about currency
speculators and their effect on currency devaluations and national economies recurs regularly. Nevertheless, economists including Milton Friedman have argued that speculators ultimately are a stabilizing influence on the market and perform the important function of providing a market for hedgers and transferring risk from those people who don't wish to bear it, to those who do.Other economists susch as Joseph Stiglitz consider this argument to be based more on politics and a free market philosophy than on economics.
Large hedge funds and other well capitalized "position traders" are the main professional speculators.
Currency speculation is considered a highly suspect activity in many countries. While investment in traditional financial instruments like bonds or stocks often is considered to contribute positively to economic growth by providing capital, currency speculation does not; according to this view, it is simply
gambling that often interferes with economic policy. For example, in 1992, currency speculation forced the Central Bank of Sweden to raise interest rates for a few days to 500% per annum, and later to devalue the krona. Former Malaysian Prime Minister Mahathir Mohamad is one well known proponent of this view. He blamed the devaluation of the Malaysian ringgit in 1997 on George Soros and other speculators.
Gregory Millman reports on an opposing view, comparing speculators to "vigilantes" who simply help "enforce" international agreements and anticipate the effects of basic economic "laws" in order to profit.
In this view, countries may develop unsustainable financial bubbles or otherwise mishandle their national economies, and forex speculators allegedly made the inevitable collapse happen sooner. A relatively quick collapse might even be preferable to continued economic mishandling. Mahathir Mohamad and other critics of speculation are viewed as trying to deflect the blame from themselves for having caused the unsustainable economic conditions. Given that Malaysia recovered quickly after imposing currency controls directly against IMF advice, this view is open to doubt.
FOREX POST2:

FOREX (FOReign EXchange market)
Forex is an inter-bank market that took shape in 1971 when global trade shifted from fixed exchange rates to floating ones. This is a set of transactions among forex market agents involving exchange of specified sums of money in a currency unit of any given nation for currency of another nation at an agreed rate as of any specified date. During exchange, the exchange rate of one currency to another currency is determined simply: by supply and demand – exchange to which both parties agree.The scope of transactions in the global currency market is constantly growing, which is due to development of international trade and abolition of currency restrictions in many nations. Global daily conversion transactions came to $1,982 billion in mid-1998 (the London market accounted for some 32% of daily turnover; the New York market exchanged approx. 18%, and the German market, 10%). Not only the scope of transactions but also the rates that mark the market development are impressive: in 1977, the daily turnover stood at five billion U.S. dollars; it grew to 600 billion U.S. dollars over ten years – to one trillion in 1992. Speculative transactions intended to derive profit from jobbing on the exchange rate differences make up nearly 80% of total transactions. Jobbing attracts numerous participants – both financial institutions and individual investors.With the highest rates of information technology development in the last two decades, the market itself changed beyond recognition. Once surrounded with a halo of caste mystique, the foreign exchange dealer’s profession became almost grasroots. Forex transactions that used to be the privilege of the biggest monopolist banks not so long ago are now publicly accessible thanks to e-commerce systems. And the foremost banks themselves also often prefer trade in electronic systems over individual bilateral transactions. E-brokers now account for 11% of the forex market turnover. The daily scope of transactions of the biggest banks (Deutsche Bank, Barclays Bank, Union Bank of Switzerland, Citibank, Chase Manhattan Bank, Standard Chartered Bank) reaches billions of dollars.The FOREX market as a place where to apply one’s personal financial, intellectual and psychic power is not designed for attempts at catching a bluebird there. Sometimes someone manages to do so but for a short time only. The key advantage of a forex market is that one can succeed there just by the strength of one’s intelligence.Another essential feature of the FOREX market, no matter how strange it might seem, is its stability. Everybody knows that sudden falls are very typical of the financial market. However, unlike the stock market, the FOREX market never falls. If shares devalue it means a collapse. But if the dollar slumps, that only means that another currency gets stronger. For instance, the yen strengthened by a quarter against the dollar late in 1998. On some days dollar fell by dozens percentage points. However, the market did not collapse anywhere; trading continued in the usual manner. It is here that the market and the related business stability lie - currency is an absolutely liquid commodity and will be always traded in.The FOREX market is a 24-hour market that does not depend on certain business hours of foreign exchanges; trade takes place among banks located in different corners of the globe. Exchange rates a`re so flexible that significant changes happen quite frequently, which enables to make several transactions every day. If we have an elaborate and reliable trade technology we can make a business, which no other business can match by efficiency. It is not without reason that the pivotal banks buy expensive electronic equipment and maintain the staffs of hundreds of traders operating in different sectors of the FOREX market.The starting costs of joining this business are very low now. Actually, it costs several thousands of dollars to take a course of initial training, to buy a computer, to purchase an information service and to create a deposit; no real business can be established with this money. With excessive offers of services, finding a reliable broker is also quite a real thing. The rest depends on the trader himself or herself. Everything depends on you personally, as in no other area of business now.The main thing the market will require for successful operations is not the quantity of money you will enter it with – the main thing is the ability to constantly focus on studying the market, understanding its mechanisms and participants’ interests; this is constant improvement of one’s trade approaches and their disciplined implementation. Nobody has achieved success in that market by forcing one’s way with one’s capital atilt. The market is stronger than anything else; it is even stronger than central banks with their huge foreign exchange reserves. George Soros, a national hero of the FOREX market, did not win the Bank of England at all, as many of us believe – he made the right guess that, with existing contradictions inherent in the European financial system, there were plenty of problems and interests that would not allow to hold the pound. That’s exactly what happened. The Bank of England, having spent nearly $20 billion to maintain the pound rate, jacked it up, by giving it in to the market. The market settled this problem, and Soros got his billion.The global monetary system has gone a long way during thousands of years of the human history, but it is surely experiencing the most exciting and earlier unthinkable changes. The two main changes determine a new image of the global monetary system:
the money is fully separated from any tangible media;
powerful information and telecommunications technologies made it possible to consolidate monetary systems of different nations into the single global financial system that has no boundaries.

Typical attractive features of the market:
liquidity:
the market operates the enormous money supply and gives absolute freedom in opening or closing a position in the current market quotation. High liquidity is a powerful magnet for any investor, because it gives him or her the freedom to open or to close a position of any size whatever.
promptness:
with a 24-hour work schedule, participants in the FOREX market need not wait to respond to any given event, as is the case in many markets.
availability:
a possibility to trade round-the-clock; a market participant need not wait to respond to any given event;
flexible regulation of the trade arrangement system:
a position may be opened for a pre-determined period of time in the FOREX market, at the investor’s discretion, which enables to plan the timing of one’s future activity in advance;
value:
the Forex market has traditionally incurred no service charges, except for the natural bid/ask market spread between the supply and the demand price;
one-valued quotations:
with high market liquidity, most sales may be carried out at the uniform market price, thus enabling to avoid the instability problem existing with futures and other forex investments where limited quantities of currency only can be sold concurrently and at a specified price;
market trend:
currency moves in a quite specific direction that can be tracked for rather a long period of time. Each particular currency demonstrates its own typical temporary changes, which presents investment managers with the opportunities to manipulate in the FOREX market;
margin:
the credit “leverage” (margin) in the FOREX market is only determined by an agreement between a customer and the bank or the brokerage house that pushes it to the market and is normally equal to 1:100. That means that, upon making a $1,000 pledge, a customer can enter into transactions for an amount equivalent to $100,000. It is such extensive credit “leverages”, in conjunction with highly variable currency quotations, which makes this market highly profitable but also highly risky.

Margin Trading System
A typical transaction amounts to $10 million in inter-bank trade. However, it is quite clear that such transaction values are not affordable for a private investor – well, at least to the overwhelming majority of them.Involvement of small and medium investors in the Forex market was facilitated by intermediacy of dealing or brokerage companies. Medium and small investors have access to the global forex market in many nations, using the sums of money starting from $2,000 in their transactions. A dealing company provides its customers with a credit line – a so-called dealing leverage, or a credit leverage, that is several times as big as the deposit. Brokers providing margin trading services require that a pledge deposit should be contributed, and provide a customer with an opportunity of entering into forex sales and purchase transactions for amounts that are 50, 100 and sometimes even 200 times as large as the deposit made. The risk of losses is borne by the customer; the deposit serves as security hedging a broker. The system of operations through a dealing (brokerage) house, with a credit leverage, was called margin trading.To put it simply, the essence of margin trading can be reduced to the following: by placing pledged capital, an investor becomes able to manage target loans provided against this pledge and to guarantee indemnification against any potential losses on open forex positions with the deposit.As mentioned above, unlike with forex transactions with actual delivery or actual currency exchange, FOREX participants, especially those with little funds, make use of trading with an insurance deposit - margin trade, or leverage trade. In case of marginal trade, each transaction must consist of the two stages – purchase/sales of foreign exchange at one price, and then its compulsory sales/purchase at another (or at the same) price. The first action is called the opening of a position; the second is the closing of a position. Opening of a position is not accompanied with actual delivery of foreign exchange, and a participant that opened the position contributes an insurance deposit that serves as guarantee of indemnification against any possible losses. Upon closing of a position, the insurance deposit is returned, and profit or losses are calculated.Any margin trading transaction must comprise two parts: opening of a position and closing of a position. For instance, when forecasting the euro goes up (looks up) vs the dollar, we want to buy a cheaper euro with dollars now and to sell it back when it rises in price. In this case, the transaction will look as follows: opening of a position – euro purchase; closing of a position – its sale. All the time until the position has been closed we have an “open euro position.” Just the same, when we believe that the euro will cheapen (look down) vs the dollar, our transaction will consist of the following steps: opening a position – sales of a more expensive euro; closing a position – purchase of a cheapened euro. Therefore, we are able to generate profit whether the exchange rate goes up or down.You can enter FOREX through an intermediary only. A dealing center may act as such intermediary. This agency provides you with a (computer or telephone) communications channel with a broker who makes available forex quotations to you and through whom you can enter into transactions. You can also operate directly from your home PC through the Internet. The last option has been becoming increasingly more common recently. The prices you can see on your computer’s screen are prices of actual transactions at FOREX.A customer concludes a contract with the company whereby the latter undertakes, at the customer’s order and in its own name, to enter into transactions. In this case, the company runs the risk of losses from entering into such transactions, so the customer deposits a certain sum of money with the bank as pledge. The amount of this deposit is determined based on the amount of transactions entered into by the bank and on the credit lever provided to the customer. If a dealing company makes losses from a concluded transaction, the investor becomes liable to it in the amount of this loss, and these liabilities are covered from the pledge deposit; if the company generates profit from a concluded transaction, it becomes liable to the investor in the amount of this profit. Generated profit is remitted to the customer’s pledge deposit. The customer’s order to the company to close an open position is a must; yet the company jobs with its own money. Otherwise the bank may close a long position with a short one, and the customer may sustain losses. The situations when cross rates change by more than two percentage points hardly ever happen in the global market, and losing his or her pledge is next to impossible if a customer jobs reasonably. If the bank’s dealer understands that potential losses, if the rate changes for the worse, might exceed the pledge deposit amount, the dealer can close a position independently, without waiting for the customer’s instructions, with losses not exceeding the pledge amount.Margin trading appeals by its affordability. Investing funds into securities of the most developed foreign countries to generate any fixed income would hardly be interesting for our compatriots. U.S. Treasury bonds are surely the most reliable and stable, but, being very expensive, they have low yield (approx. 6% p.a.) and are the object of long-term investments. Shares generate higher yield; however, dividend amount is directly dependent on successful operations of any particular enterprise and its shareholders’ preferences. Share purchase for bull transactions seems more attractive but requires greater investments. Margin trading is free from the said limitations – you can sell and buy depending on your expectations, and 1%-3% of a transaction value will do to enter into the transaction.
