Advanced GET Studies - GET Williams %R 
GET Williams %R is a momentum indicator that measures overbought/oversold levels. It was developed by Larry Williams. The interpretation of Percent R is very similar to that of the Stochastic Oscillator, except that GET Williams %R is plotted upside-down and the Stochastic Oscillator has internal smoothing. To display the GET Williams %R is indicator on an upside-down scale, it is usually plotted using negative values (for example, -20 percent). (For the purpose of analysis and discussion, simply ignore the negative symbols.) Readings in the range of 80 to 100 percent indicate that the security is oversold, while readings in the 0 to 20 percent range suggest that it is overbought.
As with all overbought/oversold indicators, it is best to wait for the security’s price to change direction before placing your trades. For example, if an overbought/oversold indicator (such as the Stochastic Oscillator or GET Williams %R is ) is showing an overbought condition, it is wise to wait for the security’s price to turn down before selling the security. (The MACD is a good indicator to monitor change in a security’s price.) It is not unusual for overbought/oversold indicators to remain in an overbought/oversold condition for a long time period as the security’s price continues to climb/fall. Selling simply because the security appears overbought may take you out of the security long before its price shows signs of deterioration.
