Hi, Larry:

First off ... you probably should pursue this in the NEW user group,
since this one is about to be shut down. EJR has posted several
reminders about this already.

Here are the PCF's you wanted. They are based on TRUE Wilder's
smoothing, with enough terms to provide <0.1% error. Greater
accuracy is possible with more terms ... my experience is that this
level is more than adequate for typical RSI interpretation. You need
to check the "Use Wilder Smoothing" box in the TC plots to see the
same thing on the screen. Note that TC does NOT use "calendar" weeks
or "calendar" months. A "Week" is the last five trading days.
A "Month" is the last 21 trading days. These formulae presume that.
