Williams % R (WillR)


The %R indicator was developed by Larry Williams and introduced in his 1979 book How I Made $1,000,000 Trading Commodities Last Year. Williams %R is similar to a stochastic oscillator, as it normalizes the price as a percentage between 0 and 100. It is basically an inverted version of the 'Raw %K' value of a Fast Stochastic.

Selecting the Williams %R indicator allows you to set the Period (as number of minutes) and the color of the result.


(\%R = -100 * ( ( Highest High - Close) / ( Highest High - Lowest Low ) )\)


  • Close = the current closing price
  • Highest High = the highest high in the past n periods
  • Lowest Low = the lowest low in the past  n periods
