I really cannot understand this. IMHO it is probably the most important tool after the humble trendline. The only way of producing a non adjustable channel is by copying and pasting a second line and thereafter manually adjusting each line. A real pain and a time waster.
The Gann Fan is included. The Fib circle is included. Both not greatly used certainly by any trader I know. The regression channel has always been is there - great - much more useful but does not always "hit the spot" as a normal channel does.
There have been so many requests over the years for this tool. Every other charting platform I know has it. Please, please include it in production release.

I think it'll allow you to do what you're looking to do until development creates an actual channel tool. Hope it helps:
