This is very interesting indicator created by cja long time ago: Original thread is this one. Fixed indicator is attached.
This indicator works great - I just checked it now: More info and free to download - go to this thread.
UniZigZagChannel_midline 600+ indicator is on this post. This indicator was improved by cja for mid level added. This version works with Metatrader 4 build 600 and above. Originally Posted by cja There was a request to add a mid level to this indicator earlier in the thread so now that the buffer restrictions no longer apply I have added the extra level.
