What are PIPS?
 
Currencies are quoted using 5 significant digits. The last digit, called a "pip", represents the smallest potential move in an exchange rate, and is very similar to ticks or points in other financial products. In the example below, a 10 pip increase in the Ask price would result in a quote of 1.2287. Likewise, a 10 pip decrease in the Ask price would result in a quote of 1.2267. Half-pips are a more recent development offering traders even tighter spreads and more competitive and transparent accuracy in pricing. When trading foreign exchange, the value of a pip is dependent on two variables – the amount of currency and the currency pair.
