The cost of establishing a position is determined by the spread, and prices are always quoted using five numbers (for example, 134.85), the final digit of which is referred to as a point or a pip. For example, if USD/JPY was quoted with a bid of 134.85 and an ask of 134.90, the five-pip spread is the cost of trading this position. From the very start, therefore, the trader must recover the five-pip cost from his or her profits, necessitating a favorable move in the position in order simply to break even.

More about Margin
Trading in the currency markets requires a trader to think in a slightly different way also about margin. Margin on the forex is not a down payment on a future purchase of equity but a deposit to the trader's account that will cover against any currency-trading losses in the future. A typical currency trading system will allow for a very high degree of leverage in its margin requirements, up to 100:1. The system will automatically calculate the funds necessary for current positions and will check for margin availability before executing any trade.

In the spot forex market, trades must be settled within two business days. For example, if a trader sells a certain number of currency units on Wednesday, he or she must deliver an equivalent number of units on Friday. But currency trading systems may allow for a "rollover", with which open positions can be swapped forward to the next settlement date (giving an extension of two additional business days). The interest rate for such a swap is predetermined, and, in fact, these swaps are actually financial instruments that can also be traded on the currency market.

In any spot rollover transaction the difference between the interest rates of the base and counter currencies is reflected as an overnight loan. If the trader holds a long position in the currency with the higher interest rate, he or she would gain on the spot rollover. The amount of such a gain would fluctuate day-to-day according to the precise interest-rate differential between the base and the counter currency. Such rollover rates are quoted in dollars and are shown in the interest column of the forex trading system. Rollovers, however, will not affect traders who never hold a position overnight since the rollover is exclusively a day-to-day phenomenon.

Conclusion
As one can immediately see, trading in forex requires a slightly different way of thinking than the way required by equity markets. Yet, for its extreme liquidity, multitude of opportunities for large profits due to strong trends and  high levels of available leverage, the currency market are hard to resist for the advanced trader. With such potential, however, comes significant risk, and traders should quickly establish an intimate familiarity with methods of risk management.

All the very best in your trading endeavors!
