Williams’ Percent Range (%R)

A technical indicator developed by Larry Williams. It is used to identify extreme price movements i.e. overbought and oversold levels. It uses an upside-down scale. Readings from 0 to -20 imply overbought levels whereas readings between 80 and 100 imply oversold levels.  The %R indicator often anticipates reversals as it forms a top and turns down before the underlying financial instrument does and similarly, it forms a bottom and turns up before the price does. To calculate %R, take the difference between the Highest High of the last n periods and the current closing price - this is the dividend.  Furthermore, take the difference between the Highest High of the last n periods and the Lowest Low of the last n periods - this is the divisor. Finally multiply the quotient by -100.
