Jason,
Thank you for the RSC afl which you submitted in #34763. I have found
it most useful.
When I run your code below on the NDX it produces very similar
results to the RSC formula in #34763 although there are some
differences.
Does the earlier RSC afl which includes the ROC function have any
particular advantage over the code below?
