. Buying and holding and dollar-cost-averaging are wonderful strategies with which to interact with the markets for a long period of time. But just because you have your investments on autopilot does not mean you should ignore the forces at work. Stay current with your investment and remain in tune with overall market conditions. Know what is happening in the companies in which you own stock.
Keep a watchful eye on commissions. If you are not the trading type, understand what you are getting for the fees you are paying. Some firms charge a monthly fee, while others charge transactional fees. Be cognizant of what you are paying and what you are getting for it. Remember, the cheapest choice is not always the best.

All currency has a value relative to other currencies on the planet. Currency trading uses the purchase and sale of large quantities of currency to leverage the shifts in relative value into profit.

There are two reasons the relative value of a currency fluctuates. The first is because of a ‘real’ market: as outside investors or visitors wish to buy things within a country, they are forced to convert their domestic currency into the currency of the country they are buying within. Similarly, as money leaves the country, people must sell their currency for the foreign currency they will need to spend or invest abroad.

EUR/USD (euro/dollar)
USD/JPY (dollar/Japanese yen)
GBP/USD (British pound/dollar)
USD/CHF (dollar/Swiss franc)

and the three commodity pairs:

AUD/USD (Australian dollar/dollar)
USD/CAD (dollar/Canadian dollar)
NZD/USD (New Zealand dollar/dollar)

These currency pairs, along with their various combinations (such as EUR/JPY, GBP/JPY and EUR/GBP) account for more than 95% of all speculative trading in FX. Given the small number of trading instruments - only 18 pairs and crosses are actively traded - the FX market is far more concentrated than the stock market.

The second force for currency fluctuation is speculation. As investors feel a given currency will act strongly or weakly, they will buy or sell accordingly. This speculation can have drastic consequences on a national currency and consequently on a country’s economy. During the East Asia Crisis in 1997, for example, as nations in Asia began facing economic downturns, speculators used currency trading to realize enormous profits and in many analysts’ view helped to exacerbate the problem.

How does this market differ from other markets?

Unlike the trading of stocks, futures or options, currency trading does not take place on a regulated exchange. It is not controlled by any central governing body, there are no clearing houses to guarantee the trades and there is no arbitration panel to adjudicate disputes. All members trade with each other based upon credit agreements. Essentially, business in the largest, most liquid market in the world depends on nothing more than a metaphorical handshake.

At first glance, this ad-hoc arrangement must seem bewildering to investors who are used to structured exchanges such as the NYSE or CME. (To learn more, see Getting To Know Stock Exchanges.) However, this arrangement works exceedingly well in practice: because participants in FX must both compete and cooperate with each other, self regulation provides very effective control over the market. Furthermore, reputable retail FX dealers in the United States become members of the National Futures Association (NFA), and by doing so they agree to binding arbitration in the event of any dispute. Therefore, it is critical that any retail customer who contemplates trading currencies do so only through an NFA member firm.

The FX market is different from other markets in some other key ways that are sure to raise eyebrows. Think that the EUR/USD is going to spiral downward? Feel free to short the pair at will. There is no uptick rule in FX as there is in stocks. There are also no limits on the size of your position (as there are in futures); so, in theory, you could sell $100 billion worth of currency if you had the capital to do it. If your biggest Japanese client, who also happens to golf with Toshihiko Fukui, the Governor of the Bank of Japan, told you on the golf course that BOJ is planning to raise rates at its next meeting, you could go right ahead and buy as much yen as you like. No one will ever prosecute you for insider trading should your bet pay off. There is no such thing as insider trading in FX; in fact, European economic data, such as German employment figures, are often leaked days before they are officially released.
