What is it?
Williams %R, also known as the Williams Percent Range, is a momentum oscillator that measures overbought and oversold levels in a market. It compares the current closing price to the highest high and lowest low over a specified period, providing insights into the market's relative positioning within that range. The indicator ranges from 0 to -100, with readings above -20 indicating overbought conditions and readings below -80 indicating oversold conditions.
