What is a pip? What does it mean?

The smallest price change that a given exchange rate can make. Since most major currency pairs are priced to four decimal places, the smallest change is that of the last decimal point - for most pairs this is the equivalent of 1/100th of one percent, or one basis point. In the Forex market, prices are quoted in pips. Pip stands for "percentage in point" and is the fourth decimal point, which is 1/100th of 1%. In EUR/USD, a 3 pip spread is quoted as 1.2500/1.2503Among the major currencies, the only exception to that rule is the Japanese yen. In USD/JPY, the quotation is only taken out to two decimal points (i.e. to 1/100 th of yen, as opposed to 1/1000th with other major currencies). In USD/JPY, a 3 pip spread is quoted as 114.05/114.08.
