I think I had a range of 0 - 10 in the first DE oriented AFL that was posted as well ... You can of course change the range of the parameter statement to whatever you like ... However, keep in mind that from the end of the CMA to the selected bar is an extrapolation based on real data ... beyond that is pure speculation and using a tool like a nth order polynomial is likely to get out of control quickly.
