Williams’ Percent Range (WPR) Indicator – Finding Better Trades With Overbought And Oversold Levels

Williams’ Percent Range is a dynamic technical indicator that determines the state of overbought-oversold. The meaning of the WPR indicator is that it measures the ability of bulls and bears to close prices every day near the edge of the range over the past period.

The analysis is carried out on the basis of studying the position of the current closing price in the range formed by extremum for previous periods. This trading tool was developed by the famous trader Larry Williams and George Lane.

Indicator calculations

The indicator line is calculated by the formula:

WPR = (MAX (HIGH (i - n)) - CLOSE (i)) / (MAX (HIGH (i - n)) - MIN (LOW (i - n))) * 100

Indicator signals

As known, the location of the price level can be considered an indicator of market equilibrium at a particular point in time. The maximum value characterizes the highest strength of buyers in the considered trading range. The minimum displays the ultimate strength of sellers. The closing price reports which of these groups won a local victory in the ended period, as well as how convincing this gain was.

By comparing the new prices with the latest trading range, the user has the opportunity to visually see if the “bulls” were able to finally gain a foothold near the high of the range or, conversely, the bears that turned out to be stronger were located near the low.

If in the presence of an uptrend, the closure occurred far from the peak, then the position of buyers is weaker than previously thought, and you should think about selling. An overbought zone is a range from -20 to 0.

If the trend is downward, but the “bears” did not manage to catch near the minimum, we can talk about the weakening of sellers, and begin to look for opportunities to buy. The oversold area is between -100 and -80.
