I am a fan of channels. I came across these (attached) that are listed as a NovelChannel indicator. These works very well with my trading but I have no idea how to duplicate and cannot get into the source code. (I want to add into the code of my own indicator). I assume it is a keltner of some sort and I have seen something like these before that are smoothed out but starting to think I am looking in the wrong direction.
Does anyone have any idea what channels these are, possible settings, or how to get re-created?
