I haven't been using CCI, so I just assumed it had a range.
So maybe it is impossible to have an indicator that is an oscillator which
goes below 50 when CCI drops below zero, and goes above 50 when CCI rises
above zero.
This kind of an oscillator would permit you to plot it along with the other
zero to 100 oscillators, and you could detect crosses with Cross( X,Y);
This might not be of much value, but I would like to test it. Ron D
