What is Forex Pip
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 1/100 of one percent, or one basis point.
For example, the smallest move the USD/CAD currency pair can make is $0.0001, or one basis point. The smallest move in a currency does not always need to be equal to one basis point, but this is generally the case with most currency pairs.
There is an exception for quotations for Japanese Yen against other currencies. For currencies in relation to Japanese Yen a pip is 0.01 or 1 cent. Then if you are trading USD/JPY in $100 000 lots, one pip will be equivalent to $1000. When a currency moves from a value of 1.4511 to 1.4514, it moved 3 pips. When a pip has a value of $10, you have gained $30.
