I use RANK all the time, but it is not native to AB, nor is it used to
find a distribution. i suggest finding what sort of output you have
from your indicator. excel can be used to visualize the output. then
you can send it thru a transformation function to squeeze it, shift
it, twist it, and so on, then cap it with a tanh or with min and max
functions. for example, i like this:
tanh(x)*abs(tanh(x))
x has values mostly around -2 to +2. this transform reduces the
values around -0.5 to +0.5 close to 0, and gives added emphasis to
those values less then -1 and greater then 1.
