Ed,
Thanks for posting. It works well.
The index is a Directional Movement Index similar to and ADX but
scaled at the Index variable from 1 to 100. At the OB/OS variable
you are simply rescaling the index to a different scale. While I
understand that you are trying to set the OB/OS levels, I think the
indicator works well just as it is.
I want to keep working with this some more but I am also tight on
time this weekend.
