DONCHIAN (Donchian Channels)

The Donchian Channel is a technical indicator developed by Richard Donchian that plots the highest high and lowest low of a security over a specific period. It creates a channel or band around the price action, helping traders identify trends, breakouts, and potential trading opportunities based on price extremes.

Formula

Upper Channel = Highest High (n periods)
Lower Channel = Lowest Low (n periods)
Middle Channel = (Upper Channel + Lower Channel) / 2
Where:
n = number of periods (typically 20)

How DONCHIAN Works

Donchian Channels work by creating a visual representation of price volatility and trends. The upper and lower bands represent the highest high and lowest low over a specified period, while the middle line represents the average of these extremes. When price breaks above the upper channel or below the lower channel, it often signals potential trend changes or continuation patterns. The width of the channel also provides information about market volatility.
