My first attempt in Pine.
It is a Donchian Channel, but in stead of the median line I added the four Fibonacci lines and colored three of the five ensuing zones in suggestive colors.
The blue zone is up trend zone
The gray zone is ranging zone
The orange zone is down trend zone.
The white zones are 'in betweens'
For the fibs to function properly it needs to be a 20 - 30 period channel.
