A foreign exchange represents the value of particular currency in another. An exchange rate between two currencies always fluctuates with time to time. The value of a currency relative to a third currency may be calculated by dividing one unit rate by another. For example if there are �300 to the dollar and �8.5 to the dollar then the number of yen per euro is 300/8.5 =35.29.The magnitude of the numbers in the list does not indicate, by themselves, the strength or weakness of a particular currency. For example the Dollar could be resettle tomorrow so that one new dollar was equal to 50 old dollars. Then fifty would multiply all the numbers in the table. However it is very useful to look at the variation of a particular exchange rate to learn the pattern of trends. It really helps in prediction of market for near future. These trends are highly sensitive to political, economic and fundamental factors that have a big influence on price. The nature for prices to trend isn"t predicted. A close look on rates of a particular currency pair will help forex trader in deciding what to do next and how market will behave in coming days.
