Pip is short of "percentage points" and is the smallest increase in forex trading. In the forex market, the price is quoted to the fourth decimal point. For example, if a bar of soap at a pharmacy is valued at $ 20, in the forex market, the same soap will be quoted at 1.2000. Changes at the fourth decimal point are called 1 pip and are usually equal to 1/100 of 1%. Among major currencies, the only exception to this rule is the Japanese yen. One Japanese yen is now worth around $ 0.01. So, in the USD / JPY pair, the quote is only taken for two decimal digits (ie at 1/100 yen, as opposed to 1/100 with the other major currencies)
