%R ++ for Amibroker (AFL)

Williams %R, or just %R, is a technical analysis oscillator showing the current closing price in relation to the high and low of the past N days (for a given N). It was developed by a publisher and promoter of trading materials, Larry Williams. Its purpose is to tell whether a stock or commodity market is trading near the high or the low, or somewhere in between, of its recent trading range.

This version of the %R indicator shows a trading ribbon as a guide and also attempts to draw darvas boxes over the indicator.
