The Williams %R is a momentum oscillator that ranges from 0 to -100, reflecting the current closing price relative to the highest high over a lookback period. Readings above -20 signal overbought conditions, while readings below -80 indicate oversold levels — making it a fast-reacting tool for timing short-term entries and exits.
This sample displays CSCO daily OHLC data on the main plot and computes the Williams %R indicator with period 12, rendered as a spline series in a 30% height subplot. The chart maps open, high, low, close, and volume fields, features dual Y-axes on both plots, and includes a synchronized line scroller, a range picker, and a range selector, with the default view from January 2004 to June 2008.
