Like many other leading indicators, Williams % R has a range and overbought-oversold levels. The range of this indicator is 0 to -100 which means the value of this indicator always lies in this range. -80 to -100 level is considered as oversold and 0 to -20 level is considered as overbought level.

The oversold region is a psychological support level and the overbought region is a psychological resistance level.
