DonchianChannel

Summary

The Donchian channel is a volatility indicator forming a channel between the highest high and the lowest low of the chosen period.

Remarks

The Donchian channel is mainly used for providing entry signals. A long is established when the price closes above the Donchian Channel. Conversely, if it closes below, then a short is established.
