What's a pip?

A pip is the smallest value in a Forex quote. Take our example earlier on EUR/USD. If the exchange rate goes from 1.2385 to 1.2386; that's one pip. In mathematical definition, a pip means the last decimal place of a quotation.Note that as each currency has its own value, the value of a pip is different from one another. Say USD/JPY rate at 120.75, a pip would be 0.01 (the second decimal place); while for EUR/USD 1.2385, a pip would be 0.0001 (the fourth decimal place).
