Return value of the Williams R% oscillator over the last N periods for the selected price.
The parameter is the number of days used in calculation of %R.
((High on n period – today’s close) / (high on n period – low on n period)) * (-100)
Williams’%R is an overbought / oversold indicator. Values -80 and -20 can be used as limits to detect overbought and oversold situations.
Nevertheless, it is better to wait for a change in the price direction, which can be detected for instance through MACD indicator analysis, before buying or selling.
Note that when %R makes a peak and reverses, a price decline often takes place.
