The Donchian channel is a useful indicator for seeing the volatility of a market price. If a price is stable the Donchian channel will be relatively narrow. If the price fluctuates a lot the Donchian channel will be wider. The two outer bands are plotted as the highest high and lowest low for a set period originally 20 days with the optional middle band calculated as the average of the two.
Calculation: Donchian Channels:
1) Upper Channel = 20 Day High;
2) Lower Channel = 20 Day Low;
3) Middle Channel = (20 Day High + 20 Day Low)/2;
