Credit Card Applications

Before we get into shopping for a card, let's go over some important terms you'll encounter in credit-card brochures or discussions with potential lenders:
· Annual fee - A flat, yearly charge similar to a membership fee
· Many companies offer "no annual fee" cards today, and lenders who do charge annual fees are often willing to waive them to keep your business.
· Finance charge - The dollar amount you pay to use credit
· Besides interest costs, this may include other charges such as cash-advance fees, which are charged against your card when you borrow cash from the lender. (You generally pay higher interest on cash advances than on purchases -- check your latest bill to find out what you're paying for this service!)
· Grace period - A time period, usually about 25 days, during which you can pay your credit-card bill without paying a finance charge
· Under almost all credit-card plans, the grace period only applies if you pay your balance in full each month. It does not apply if you carry a balance forward. Also, the grace period does not apply to cash advances.
· Annual percentage rate (APR) - The yearly percentage rate of the finance charge
· Interest rates on credit-card plans change over time. Some of these adjustments are tied to changes in other interest rates, such as the prime rate or the Treasury Bill rate, and are called variable-rate plans. Others are not explicitly tied to changes in other interest rates and are called fixed-rate plans.
· Fixed rate - A fixed annual percentage rate of the finance charge
· Variable rate - Prime rate (which varies) plus an added percentage (For example, your rate may be PR + 3.9 percent.)
· Introductory rate - A temporary, lower APR that usually lasts for about six months before converting to the normal fixed or variable rate (This is a hot topic -- more about it later.)
Experts say that if you're smart, you'll do the same kind of comparison shopping for a credit card that you do when you're looking for a mortgage or a car loan. This is a good idea because the choices you make can save you money. The process is not a simple one -- here are some tips that should help you get started:
1. Do some research - There are plenty of places, both online and offline, where you can read about credit-card offerings and even get credit-card ratings, but since rates and plans change so often, it's a good idea to call the institutions you're interested in to confirm the information and to see if there are other plans that might work for you.
A reliable and non-commercial resource is the Federal Reserve Board. Also, the non-profit consumer credit organization U.S. Citizens for Fair Credit Card Terms offers credit-card ratings from its research (and so do a lot of commercial organizations -- many of whom are also credit-card issuers).
2. Make a list - Make a list of credit-card features that fit your financial needs and rank the features according to how you plan to use the card and pay your monthly bill.
3. Review the plans - Review all of the information you've gathered on different plans. Pay special attention to the APR - - you want a low rate, but not necessarily the lowest. This is because, depending on your lifestyle and payment habits, you might benefit more from a card that offers cash rebates, discounts or frequent-flier miles.
4. Check out credit unions - Look into the possibility of joining a credit union. Credit unions are non-profit, and they have lower overhead so they can charge lower interest rates. Credit unions are newer to the credit industry so they are eager to generate credit-card loans. However, you'll probably be required to open a share account or savings account to join.
Credit unions typically are limited to a particular employer and its employees, but that's changing. Due to industry consolidations, credit unions are rapidly expanding their fields of membership. To find out which credit union you may be eligible to join, contact the Credit Union National Association (CUNA).
5. Compare plans - If you already have a credit card, be sure that you're making a good move before you swap cards. If you are a current cardholder and have a good credit rating, see if the institution that issued your card will lower your current rate. Don't be afraid to negotiate!
These are steps to take when deciding on a credit card. But your actual breadth of options depends in great part on your credit history.

Credit Card Safety

Although the numbers are increasing, consumers are still not using their credit cards on the Internet nearly as much as e-tailers (electronic retailers) would like. That's why many cyber-merchants continue to offer a toll-free order number so that shoppers have the choice of calling their order in. Cyber-shopping may be convenient -- and some people do all of their shopping online -- but credit-card fraud is always a threat, both on the Internet and out in the real world. Hackers have found ways to steal credit-card numbers from Web sites.
To illustrate the importance of tight security, a network TV reporter, tipped off about loose security on an Internet Web-hosting site, was able to gain access to about 1,500 customer records, which included everything from credit-card numbers and payment records to comments about particular customers.
These are the kinds of stories that deflate consumer confidence. Some e-tailers blame consumer reluctance on the inability in cyberspace to make the kind of personal contact that a shopper gets when he looks into the eyes of a store merchant. Experts say that this kind of comfort level will be boosted when online payment methods and security measures are standardized -- much as they are in the retail and mail-order industries.
While Internet companies have taken responsibility for security breaches and resulting losses to credit-card users, there remains the growing problem of identity thieves who use stolen credit cards to make purchases on the Internet. And while unfair or fraudulent practices by credit-card companies are not commonplace, they do happen. The good news is that consumers are protected by law -- in case of credit-card fraud online or off, you are only liable for a maximum of $50 of the amount stolen.
And fortunately, the Federal Trade Commission (FTC) and the media are watching closely. In 1994, the FTC ordered TransUnion credit-reporting bureau to stop selling "sensitive" consumer data -- data on 160 million Americans -- to junk-mail producers. The FTC charged that TransUnion violated the Fair Credit Reporting Act by selling consumer information to target marketers who lack any of the allowable purposes listed under the act. TransUnion denies that it sold information that could affect customers' appealed the FTC's ruling, but lost.
If the mailing-list issue bothers you -- and it bothers most of us -- pay attention when you're completing that credit-card application. Some application forms now provide a box that you can check to allow or disallow the selling of your information to mailing lists. You can also protect yourself by taking your name off the credit bureaus' mailing lists.
One way to do this is to visit The Consumer Credit Reporting Industry Opt-Out Prescreen Web site. On this site you can fill out a form and opt-out of recieving pre-approved credit or insurance offers in the mail. You can also call 888-5-OPT-OUT (888-567-8688). Alternatively, you can write to the major credit card bureaus and request that your named be removed from their mailing lists.
When you write to these companies, include your complete name, name variations and mailing address, Social Security number and signature and state clearly that you want your name removed from their mailing lists. You can write any of these major reporting bure aus and they will contact the other major bureaus with your request:
· Experian Consumer Opt Out, 701 Experian Parkway, Allen, Texas, 75013
· Equifax Inc. Options, P.O. Box 740123, Atlanta, Georgia, 30374-0123
· Trans Union Marketing List Opt Out, P.O. Box 97328, Jackson, MS 39288-7328
The Direct Marketing Association (DMA) tracks consumers who prefer not to receive solicitations by mail or phone. Check their Consumer Assistance site for more information. There are a lot of simple steps you can take to protect yourself and your credit card -- starting with making sure you sign it as soon as it arrives in the mail.
These tips are important and universal:
· Sign your card -- as soon as you receive it! (Obviously, this is only as effective as the clerk who's checking it.)
· When you use your card at an ATM, enter your PIN in such a way that no one can easily memorize your keystrokes.
· Don't leave your receipt behind at the ATM.
Your PIN and account number from a discarded receipt could make you vulnerable to credit-card fraud. Also, don't throw out your credit-card statement, receipts or carbons without first shredding them!
· Never give your credit-card number over the telephone unless you initiated the call.Even when you place the call to a legitimate merchant (such as a mail-order company), never give your card number out over a cordless phone. Radio scanners that eavesdrop on these conversations are available for a few hundred dollars at any electronics store, and your voice can be received by one from a far greater distance than the maximum useful range of your cordless phone. One common scam is when someone calls you "back" right after you place an order, claims to be from the merchant and tells you that there was a problem with your card number -- would you mind giving it to them again? The best thing to do is ask for a contact name and call the merchant back at the number you used originally.
· Ignore any credit-card offer that requires you to spend money up-front or fails to disclose the identity of the card issuer.
· Make certain you get your card back after you make a purchase (one habit to observe is to leave your wallet open in your hand until you have the card back). Also, make sure that you personally rip up any voided or cancelled sales slips.
· Always keep a list of your credit cards, credit-card numbers and toll-free numbers in case your card is stolen or lost.
· Check your monthly statement to make certain all charges are your own, and immediately notify the card issuer of any errors or unauthorized charges. (More on this later!)
Now, you get a credit-card application and there's all this small print. Want to know what it's really saying?

Smart Cards

The "smart" credit card is an innovative application that involves all aspects of cryptography (secret codes), not just the authentication we described in the last section. A smart card has a microprocessor built into the card itself. Cryptography is essential to the functioning of these cards in several ways:
· The user must corroborate his identity to the card each time a transaction is made, in much the same way that a PIN is used with an ATM.
· The card and the card reader execute a sequence of encrypted sign/countersign-like exchanges to verify that each is dealing with a legitimate counterpart.
· Once this has been established, the transaction itself is carried out in encrypted form to prevent anyone, including the cardholder or the merchant whose card reader is involved, from "eavesdropping" on the exchange and later impersonating either party to defraud the system.
This elaborate protocol is conducted in such a way that it is invisible to the user, except for the necessity of entering a PIN to begin the transaction.
Smart cards first saw general use in France in 1984. They are now hot commodities that are expected to replace the simple plastic cards most of us use now. Visa and MasterCard are leading the way in the United States with their smart card technologies.
The chips in these cards are capable of many kinds of transactions. For example, you could make purchases from your credit account, debit account or from a stored account value that's reloadable. The enhanced memory and processing capacity of the smart card is many times that of traditional magnetic-stripe cards and can accommodate several different applications on a single card. It can also hold identification information, keep track of your participation in an affinity (loyalty) program or provide access to your office. This means no more shuffling through cards in your wallet to find the right one -- the smart card will be the only one you need!
Experts say that internationally accepted smart cards will be increasingly available over the next several years. Many parts of the world already use them, but their reach is limited. The smart card will eventually be available to anyone who wants one, but for now, it's available mostly to those participating in special programs.

The Stripe on a Credit Card


The stripe on the back of a credit card is a magnetic stripe, often called a magstripe. The magstripe is made up of tiny iron-based magnetic particles in a plastic-like film. Each particle is really a tiny bar magnet about 20-millionths of an inch long.

Illustration by Rosaleah Rautert

Your card has a magstripe on the back and a place for your all-important signature.

The magstripe can be "written" because the tiny bar magnets can be magnetized in either a north or south pole direction. The magstripe on the back of the card is very similar to a piece of cassette tape (see How Cassette Tapes Work for details).
A magstripe reader (you may have seen one hooked to someone's PC at a bazaar or fair) can understand the information on the three-track stripe. If the ATM isn't accepting your card, your problem is probably either:

· A dirty or scratched magstripe
· An erased magstripe (The most common causes for erased magstripes are exposure to magnets, like the small ones used to hold notes and pictures on the refrigerator, and exposure to a store's electronic article surveillance (EAS) tag demagnetizer.)
There are three tracks on the magstripe. Each track is about one-tenth of an inch wide. The ISO/IEC standard 7811, which is used by banks, specifies:
· Track one is 210 bits per inch (bpi), and holds 79 6-bit plus parity bit read-only characters.
· Track two is 75 bpi, and holds 40 4-bit plus parity bit characters.
· Track three is 210 bpi, and holds 107 4-bit plus parity bit characters.
Your credit card typically uses only tracks one and two. Track three is a read/write track (which includes an encrypted PIN, country code, currency units and amount authorized), but its usage is not standardized among banks.
The information on track one is contained in two formats: A, which is reserved for proprietary use of the card issuer, and B, which includes the following:
· Start sentinel - one character
· Format code="B" - one character (alpha only)
· Primary account number - up to 19 characters
· Separator - one character
· Country code - three characters
· Name - two to 26 characters
· Separator - one character
· Expiration date or separator - four characters or one character
· Discretionary data - enough characters to fill out maximum record length (79 characters total)
· End sentinel - one character
· Longitudinal redundancy check (LRC) - one character
LRC is a form of computed check character.
The format for track two, developed by the banking industry, is as follows:
· Start sentinel - one character
· Primary account number - up to 19 characters
· Separator - one character
· Country code - three characters
· Expiration date or separator - four characters or one character
· Discretionary data - enough characters to fill out maximum record length (40 characters total)
· LRC - one character
For mo re information on track format, see ISO Magnetic Stripe Card Standards.
There are three basic methods for determining whether your credit card will pay for what you're charging:
· Merchants with few transactions each month do voice authentication using a touch-tone phone.
· Electronic data capture (EDC) magstripe-card swipe terminals are becoming more common -- so is swiping your own card at the checkout.
· Virtual terminals on the Internet
This is how it works: After you or the cashier swipes your credit card through a reader, the EDC software at the point-of-sale (POS) terminal dials a stored telephone number (using a modem) to call an acquirer. An acquirer is an organization that collects credit-authentication requests from merchants and provides the merchants with a payment guarantee.
When the acquirer company gets the credit-card authentication request, it checks the transaction for validity and the record on the magstripe for:
· Merchant ID
· Valid card number
· Expiration date
· Credit-card limit
· Card usage

Single dial-up transactions are processed at 1,200 to 2,400 bits per second (bps), while direct Internet attachment uses much higher speeds via this protocol. In this system, the cardholder enters a personal identification number (PIN) using a keypad.
The PIN is not on the card -- it is encrypted (hidden in code) in a database. (For example, before you get cash from an ATM, the ATM encrypts the PIN and sends it to the database to see if there is a match.) The PIN can be either in the bank's computers in an encrypted form (as a cipher) or encrypted on the card itself. The transformation used in this type of cryptography is called one-way. This means that it's easy to compute a cipher given the bank's key and the customer's PIN, but not computationally feasible to obtain the plain-text PIN from the cipher, even if the key is known. This feature was designed to protect the cardholder from being impersonated by someone who has access to the bank's computer files.
Likewise, the communications between the ATM and the bank's central computer are encrypted to prevent would-be thieves from tapping into the phone lines, recording the signals sent to the ATM to authorize the dispensing of cash and then feeding the same signals to the ATM to trick it into unauthorized dispensing of cash.
If this isn't enough protection to ease your mind, there are now cards that utilize even more security measures than your conventional credit card: Smart Cards.

What Credit Card Numbers Mean

Although phone companies, gas companies and department stores have their own numbering systems, ANSI Standard X4.13-1983 is the system used by most national credit-card systems.

Illustration by Rosaleah Rautert

The front of your credit card has a lot of numbers -- here's an example of what they might mean.

Here are what some of the numbers stand for:

· The first digit in your credit-card number signifies the system:
· 3 - travel/entertainment cards (such as American Express and Diners Club)
· 4 - Visa
· 5 - MasterCard
· 6 - Discover Card
· The structure of the card number varies by system. For example, American Express card numbers start with 37; Carte Blanche and Diners Club with 38.
· American Express - Digits three and four are type and currency, digits five through 11 are the account number, digits 12 through 14 are the card number within the account and digit 15 is a check digit.
· Visa - Digits two through six are the bank number, digits seven through 12 or seven through 15 are the account number and digit 13 or 16 is a check digit.
· MasterCard - Digits two and three, two through four, two through five or two through six are the bank number (depending on whether digit two is a 1, 2, 3 or other). The digits after the bank number up through digit 15 are the account number, and digit 16 is a check digit.

Introduction to How Credit Cards Work



Have you ever stood behind someone in line at the store and watched him shuffle through a stack of what must be at least 10 credit cards? Consumers with this many cards are still in the minority, but experts say that the majority of U.S. citizens have at least one credit card -- and usually two or three. It's true that credit cards have become important sources of identification -- if you want to rent a car, for example, you really need a major credit card. And used wisely, a credit card can provide convenience and allow you to make purchases with nearly a month to pay for them before finance charges kick in.
That sounds good, in theory. But in reality, many consumers are unable to take advantage of these benefits because they carry a balance on their credit card from month to month, paying finance charges that can go up to a whopping 23 percent. Many find it hard to resist using the old "plastic" for impulse purchases or buying things they really can't afford. The numbers are striking: In 1999, American consumers charged about $1.2 trillion on their general-purpose credit cards.
In this article we'll look at the credit card -- how it works both financially and technically -- and we'll offer tips on how to shop for a credit card. (Experts say this should be a project on the scale of shopping for a car loan or mortgage!) We'll also describe the different credit-card plans available, talk about your credit history and how that might affect your card options, and discuss how to avoid credit-card fraud -- both online and in the real world.
Let's start at the beginning. A credit card is a thin plastic card, usually 3-1/8 inches by 2-1/8 inches in size, that contains identification information such as a signature or picture, and authorizes the person named on it to charge purchases or services to his account -- charges for which he will be billed periodically. Today, the information on the card is read by automated teller machines (ATMs), store readers, and bank and Internet computers.
According to Encyclopedia Britannica, the use of credit cards originated in the United States during the 1920s, when individual companies, such as hotel chains and oil companies, began issuing them to customers for purchases made at those businesses. This use increased significantly after World War II.
The first universal credit card -- one that could be used at a variety of stores and businesses -- was introduced by Diners Club, Inc., in 1950. With this system, the credit-card company charged cardholders an annual fee and billed them on a monthly or yearly basis. Another major universal card -- "Don't leave home without it!" -- was established in 1958 by the American Express company.
Later came the bank credit-card system. Under this plan, the bank credits the account of the merchant as sales slips are received (this means merchants are paid quickly -- something they love!) and assembles charges to be billed to the cardholder at the end of the billing period. The cardholder, in turn, pays the bank either the entire balance or in monthly installments with interest (sometimes called carrying charges).
The first national bank plan was BankAmericard, which was started on a statewide basis in 1959 by the Bank of America in California. This system was licensed in other states starting in 1966, and was renamed Visa in 1976.
Other major bank cards followed, including MasterCard, formerly Master Charge. In order to offer expanded services, such as meals and lodging, many smaller banks that earlier offered credit cards on a local or regional basis formed relationships with large national or international banks

Robotic ..... I Love this field



"How old are you?" she wanted to know.
"Thirty-two," I said.
"Then you don't remember a world without robots. To you, a robot is a robot. Gears and metal; electricity and positrons. Mind and iron! Human-made! If necessary, human-destroyed! But you haven't worked with them, so you don't know them. They're a cleaner better breed than we are."
-from I, Robot by Isaac Asimov










Robot, which is derived from a Czech word meaning "menial labor," got its modern meaning from a 1920 play, R.U.R. (Rossum's Universal Robots), by Czech playwright Karel Capek (1890-1938). The robots in Capek's play develop emotions and overthrow their human masters. A sinister "power struggle" with robots has long been a popular theme in science fiction --- for a change of pace, try Isaac Asimov's "I Robot" stories in which he consciously strove to depict robots as a benefit to society.
Today, robots are used in many ways, from lawn mowing to auto manufacturing. Scientists see practical uses for robots in performing socially undesirable, hazardous or even "impossible" tasks --- trash collection, toxic waste clean-up, desert and space exploration, and more. AI researchers are also interested in robots as a way to understand human (and not just human) intelligence in its primary function -- interacting with the real world.

"[T]he emergence of the robotics industry, which is developing in much the same way that the computer business did 30 years ago. ... Meanwhile some of the world's best minds are trying to solve the toughest problems of robotics, such as visual recognition, navigation and machine learning. And they are succeeding. ... I can envision a future in which robotic devices will become a nearly ubiquitous part of our day-to-day lives. I believe that technologies such as distributed computing, voice and visual recognition, and wireless broadband connectivity will open the door to a new generation of autonomous devices that enable computers to perform tasks in the physical world on our behalf. We may be on the verge of a new era, when the PC will get up off the desktop and allow us to see, hear, touch and manipulate objects in places where we are not physically present. ... Because the new machines will be so specialized and ubiquitous--and look so little like the two-legged automatons of science fiction--we probably will not even call them robots."
Robot Pals. Scientific American Frontiers (April 13, 2005). Alan Alda [host]: "The problem with most robots is that they tend to be, well, robotic. They know nothing they aren't programmed to know, and can do nothing they aren't programmed to do. But for many applications where robots could be useful, they need to be more like humans, able to respond as a cooperative partner rather than a mindless machine. In this program, we'll meet some robots that are learning to figure out for themselves what their human companions have in mind."

Speculation vs investment

It is very important that the individual wanting to trade foreign exchange be aware of the very marked difference between speculation and investment. Forex trading is by nature a speculative occupation. Foreign exchange markets are amongst the most volatile markets in the world. When traded on a margined basis they effectively become the most volatile in the world. Day trading in foreign exchange can be extremely profitable and high-risk profile traders can generate huge percentage returns even overnight. Day trading is however a mentally and psychologically challenging activity and is by no means meant for everyone. Day trading is essentially speculation and day traders essentially only do that: day trading. Most people who trade foreign exchange are not professional day traders however.Often the contractors of foreign exchange brokerage services are professionals in some capacity or other. These people do not day trade but take the occasional position from time to time. This is also speculation and should not be confused with making an investment.The conclusion here is that the nature of foreign exchange trading not lend itself as much to investment as it does to speculation and hedging (hedging may be performed in forward instruments). It is possible in a sense to make an investment in foreign exchange over a long-term period but this necessitates a large account value and low leveraging.

Main forex markets

Foreign exchange is traded essentially in two distinctive ways. Over an organized exchange and 'over the counter'. Exchange traded foreign exchange represents a very small portion of the total foreign exchange market the great majority of foreign exchange deals being traded between banks and other market participants 'over the counter'.1. Exchange traded currenciesIn the case of an organized exchange like the Chicago Mercantile exchange (CME) in the US, standardized currency contract sizes that represent a certain monetary value are traded in the International money market (IMM). A central clearing house organizes matching of transactions between counter-parties. There are various disadvantages to trading currency futures as outlined in the chapter Advantages of trading FX.2. Forex marketIn comparison the over the counter market is traded around the world by a multitude of participants and price quality, reputation and trading conditions determine who a participant wishes to trade with. It is probably the most competitive market in the world and brokers like ACM must insure they live up to the highest standards of service and be compliant with market standards and practices if they want to acquire new customers and retain their existing ones. In 1998 a survey under the auspices of the Bank for International Settlements (BIS), global turnover of reporting dealers was estimated at about USD 1.49 trillion per day. In comparison, currency futures turnover was estimated at USD 12 billion.Among the various financial centers around the world, the largest amount of foreign exchange trading takes place in the United Kingdom, even though that nation's currency, the British pound is less widely traded in the market than several others. As shown in the graph underneath, the United Kingdom accounts for about 32 percent of the global total; the United States ranks a distant second with about 18 percent, and Japan is third with 8 percent.

Advantages of trading forex

Although the forex market is by far the largest and most liquid in the world, day traders have up to now focused on seeking profits in mainly stock and futures markets. This is mainly due to the restrictive nature of bank-offered forex trading services.Advanced Currency Markets (ACM) offers both online and traditional phone forex trading services to the small investor with minimum account opening values starting at 5000 USD.There are many advantages to trading spot foreign exchange as opposed to trading stocks and futures. Below are listed those main advantages.1. Bid/Ask Spread ratesSpread rates have tightened dramatically in the last years. Most online forex brokers offer a spread of 5 pips on EURUSD which is the most widely traded and liquid currency pair. ACM offers a 3 pip spread on EURUSD. In stock trading, only liquid stocks offer tight spreads. Those spreads often represent on average between 0.04% and 0.06% of the value of the stock. In comparison ACM offers a 3 pip spread on all major currencies, this equates to approximately between 0.02% and 0.03% on the underlying dollar value.Exact percentages at current rates (May 2002)EURUSD 3 pips 0.03%GBPUSD 3 pips 0.03%USDJPY 3 pips 0.023%USDCHF 3 pips 0.018%In the futures market spreads can vary anywhere between 5 and 9 pips and can become even larger under illiquid market conditions (which tends to happen substantially more often in futures currencies).2. CommissionsACM offers foreign exchange trading commission free. This is in sharp contrast to (once again) what stock and futures brokers offer. A stock trade can cost anywhere between USD 5 and 30 per trade with online brokers and typically up to USD 150 with full service brokers. Futures brokers can charge commissions anywhere between USD 10 and 30 on a round turn basis.3. Margins requirementsACM offers a foreign exchange trading with a 1% margin. In layman's terms that means a trader can control a position of a value of USD 1'000'000 with a mere USD 10'000 in his account. By comparison, futures margins are not only constantly changing but are also often quite sizeable. Stocks are generally traded on a non-margined basis and when they are, it can be as restrictive as 50% or so.4. 24 hour marketForeign exchange market trading occurs over a 24 hour period picking up in Asia around 24:00 CET Sunday evening and coming to an end in the United States on Friday around 23:00 CET. Although ECNs (electronic communications networks) exist for stock markets and futures markets (like Globex) that supply after hours trading, liquidity is often low and prices offered can often be uncompetitive.5. No Limit up / limit downFutures markets contain certain constraints that limit the number and type of transactions a trader can make under certain price conditions. When the price of a certain currency rises or falls beyond a certain pre-determined daily level traders are restricted from initiating new positions and are limited only to liquidating existing positions if they so desire. This mechanism is meant to control daily price volatility but in effect since the futures currency market follows the spot market anyway, the following day the futures market may undergo what is called a 'gap' or in other words the futures price will re-adjust to the spot price the next day. In the OTC market no such trading constraints exist permitting the trader to truly implement his trading strategy to the fullest extent. Since a trader can protect his position from large unexpected price movements with stop-loss orders the high volatility in the spot market can be fully controlled.6. Sell before you buyEquity brokers offer very restrictive short-selling margin requirements to customers. This means that a customer does not possess the liquidity to be able to sell stock before he buys it. Margin wise, a trader has exactly the same capacity when initiating a selling or buying position in the spot market. In spot trading when you're selling one currency, you're necessarily buying another.

How To Choose a Forex Trading System That Works and Suits You

There are so many different trading systems you could use to trade the forex market, some better suited to certain people than others. For example some people may find it easier to comprehend and take into account fundamental factors as opposed to looking at a screen covered in technical indicators, and vice-versa.The first logical step in determining what type of trading system would best suit you is actually being aware and understand the widely known methods of analysis used in trading the currency market. Once you are aware of the tools that are available, you can generally tell what type of analysis suits you. For example some of the main technical analysis methods which are popular include:Pivot pointsChart patternsFibonacci retracementsCandlestick patternsAnd some fundamental factors which are widely used include analyzing:Interest ratesTrade balancesUnemployment ratesGross domestic product (GDP)You may now actually be able to develop your own system by combining certain methods of analysis together, giving you a method which you are comfortable with. On the other hand you may decide that you would like to trade someone else’s system, either way, that brings us to the next step which is determining the profitability of a trading system.Determining ProfitabilityMost people would think that back testing is the best way to determine a systems profitability. However back testing doesn’t always give you a true idea of how profitable a system is. The reason for this is because when you’re back testing your system on historical charts, you are only seeing the obvious setups which have occurred, and not always seeing the ones that are less obvious. These less obvious ones sometimes can produce losses, which is why back testing isn’t always the best method to implement.A better method of determining profitability is by trading your system in real-time with a demo account. This would give you a true understanding of what your system is capable of. This would also allow you to familiarize yourself with your trading platform at the same time. When determining profitability you must look at it in terms of expectancy and opportunity.Expectancy & OpportunityThese two factors together will be able to tell you what you could expect to make over a period of time. Expectancy is calculated with the following formula:(Probability of winning × average win) – (Probability of losing × average loss)This will give you a figure which is the average amount you can expect to make per trade. This shouldn’t be a negative amount, if it is you should look at some other method of trading since you cannot make money on a system that produces a negative expectancy. Obviously the higher this figure is the better. Now to the opportunity factor.The opportunity factor is how often you are able to trade using your system. By multiplying your expectancy figure with your opportunity factor it will tell you how much you could expect to make over a period of time. The more opportunity you have to trade, the more money you should expect to make. This now brings us to the last component of a trading system, money management.Money ManagementWithout proper money management you will end up as a statistic. In other words one of those 90%+ of traders who loose their money. Money management tells you how much of your account balance to risk per trade. The whole point of money management is to ensure your survival over the long term, and to preserve your capital.The most common form of money management is the percent risk model which tells you not to risk more than x percent of your account balance on any one trade. A range between 1-3% is generally an accepted amount which has been a reliable percentage to use in order to make money in the long term.ConclusionBy taking into consideration the above factors you will be able to determine if a trading system best suits you, and with some simple mathematical calculations you will be able to determine its profitability

The price of one currency in terms of another is called an exchange rate.The market itself is actually a worldwide network of traders, connected by telephone lines and computer screens there is no central headquarters. There are three main centers of trading, which handle the majority of all FX transactions United Kingdom, United States, and Japan .

what is forex

FOREX (FOReign EXchange market) is an international foreign exchange market, where money is sold and bought freely. In its present condition FOREX was launched in the 1970s, when free exchange rates were introduced, and only the participants of the market determine the price of one currency against the other proceeding from supply and demand.As far as the freedom from any external control and free competition are concerned, FOREX is a perfect market. It is also the biggest liquid financial market. According to various assessments, money masses in the market constitute from 1 to 1.5 trillion US dollars a day. (It is impossible to determine an absolutely exact number because trading is not centralized on an exchange.) Transactions are conducted all over the world via telecommunications 24 hours a day from 00:00 GMT on Monday to 10:00 pm GMT on Friday. Practically in every time zone (that is, in Frankfurt-on-Main, London, New York, Tokyo, Hong Kong, etc.) there are dealers who will quote currencies.FOREX is a more objective market, because if some of its participants would like to change prices, for some manipulative purpose, they would have to operate with tens of billions dollars. That is why any influence by a single participants in the market is practically out of the question. The superior liquidity allows the traders to open and/or close positions within a few seconds. The time of keeping a position is arbitrary and has no limits: from several seconds to many years. It depends only on your trading strategies. Although the daily fluctuations of currencies are rather insignificant, you may use the credit lines, that are accessible even to currency speculators with small capitals ($ 1,000 - 5,000), where the profit may be impressive. (You can learn more about it in the section: The main principles of trading.)The idea of marginal trading stems from the fact that in FOREX speculative interests can be satisfied without a real money supply. This decreases overhead expenses for transferring money and gives an opportunity to open positions with a small account in US dollars, buying and selling a lot of other currencies. That is, on can conduct transactions very quickly, getting a big profit, when the exchange rates go up or down. Many speculative transactions in the international financial markets are made on the principles of marginal trading.Margin trading is trading with a borrowed capital. Marginal trading in an exchange market uses lots. 1 lot equals approximately $100,000, but to open it it is necessary to have only from 0.5% to 4% of the sum.For example, you have analyzed the situation in the market and come to the conclusion that the pound will go up against the dollar. You open 1 lot for buying the pound (GBP) with the margin 1% (1:1000 leverage) at the price of 1.49889 and wait for the exchange rate to go up. Some time later your expectations become true. You close the position at 1.5050 and earn 61 pips (about $ 405). For the calculation of 1 pip click here.Everyday fluctuations of currencies constitute about 100 to 150 pips, giving FX traders an opportunity to make money on these changes.In FOREX, it's not obligatory to buy some currency first in order to sell it later. It's possible to open positions for buying and selling any currency without actually having it. Usually Internet-brokers establish the minimum deposit such as $ 2000, for working in the FOREX market, and grant a leverage of 1:100. That is, opening the position at $100,000, a trader invests $1,000 and receives $99.000 as a credit. The major currencies traded in FOREX, are Euro (EUR), Japanese yen (JPY), British Pound (GBP), and Swiss Franc (CHF). All of them are traded against the US dollar (USD).In order to assess the situation in the market a trader has to be able to use fundamental and/or technical analysis, as well as to make decisions in the constantly changing current of information about political and economic character. Most small and medium players in financial markets use technical analysis. Technical analysis presupposes that all the information about the market and its further fluctuations is contained in the price chain. Any factor, that has some influence on the price, be it economic, political or psychological, has already been considered by the market and included in the price. The initial data for a technical analysis are prices: the highest and the lowest prices, the price of opening and closing within a certain period of time, and the volume of transactions.A technical analysis is founded on three suppositions:Movement of the market considers everything;Movement of prices is purposeful;History repeats itself. That is, technical analysis is a statistical and mathematical analysis of previous quotes and a prognosis of coming prices.A number of technical indicators have been installed into the PRO-CHARTS trading system. Analyzing the indicators one can come to the conclusion about further movements of the quoted currencies. For a more detailed description of the indicators, analyzing price charts and volumes of trading, click here.Fundamental analysis is an analysis of current situations in the country of the currency, such as its economy, political events, and rumors. The country's economy depends on the rate of inflation and unemployment, on the interest rate of its Central Bank, and on tax policy. Political stability also influences the exchange rate. Policy of the Central Bank has a special role, as concentrated interventions or refusal from them greatly influence the exchange rate.At the same time one should not consider fundamental analysis just as an analysis of the economic situation in the country itself. A far bigger role in the FOREX market belongs to the expectations of the market participants and their assessment of these expectations. Various prognoses and bulletins, issued by the participants, have a strong influence on the expectations. Very often an effect of the so-called self-filfilling prophecy occurs when market players raise or lower the exchange rates according to the prognosis. But a deep and thorough fundamental analysis is available only for big banks with a staff of professional analysts and constant access to a wide field of information.In spite of these different approaches, both forms of analyses complement one another. Traders who act on the basis of a fundamental analysis, have to consider some technical characteristics of the market (the main rates of support, such as resistance and resale), and supporters of the technical approach to the market must track the main news (interest rates, important political events).
