The Wm%R (Williams %R) is a technical indicator developed by Larry Williams. It is presented in the form of an oscillator that generally varies between 0 and -100 and is used to measure the level of overbought or oversold of an asset.

Its calculation compares the current closing price to the range (highest - lowest) over a given period (for example 14 days). The closer the value of the Wm%R is to 0, the more the market is in a situation of overbought, and conversely, the closer it is to -100, the more the market is considered oversold.

Classic zones of interpretation:

- Between -20 and 0: overbought, risk of possible downward correction.

- Between -100 and -80: oversold, possibility of bullish rebound.

Crossovers around these areas, as well as divergences between the Wm%R and the price movement, can indicate a trend slowdown or a potential reversal. As with any indicator, it is recommended to use it in addition to other tools (moving averages, RSI, MACD, etc.) and to always take into account the overall market context.
