I think you all know Donchian Channels. so I am not going to write about it.
With this indicator I tried to create Donchian Trend Ribbon by using Donchian Channels.
How it works ? - it calculates main trend direction by using the length that is user-defined. so you can change it as you wish - then it calculates trend direction for each 9 lower lengths. if you set the length = 20 then the lengths are 19, 18,...11 - and it checks if the trend directions that came from lower lengths is same or not with main trend direction. - it changes the trend color of the ribbon. -
Warning: Entry points may also represents trend reversal. So you should use stoploss line if you decide to take buy/sell positions.
P.S. I didn't backtest it, it's non-repainting, it should be used educational purposes only.
