A pip, short for point in percentage, is a very small measure of change in a currency pair in the forex market. It can be measured in terms of the quote or in terms of the underlying currency. A pip is a standardized unit and is the smallest amount by which a currency quote can change. It is usually $0.0001 for U.S.-dollar related currency pairs. A fractional pip or point is equivalent to 1/10 of a pip.
There are 10 points to every 1 pip.
