Happy new year everyone

I need a different version of this indicator;
the problem is when it reaches to 0 or 1 level, it becomes a flat line, but I need to know exactly what happens in that areas because I use it for divergence.
do you have any ideas?

This is a kind of correlation, divergence and stochastic indicator all in one It shows the divergence of two symbols using stochastic as values and a criteria for divergence. Posting the original description here too : _____________________________ This one is from the book a friend sent to me ...
