Thanks for your emails
Here's the moving pearson correlation from expo that you were looking for.
http://www.lmt-expo.com/xpl.htm
They have their own programming language "XPL ... time-series programming
language ..."
Best regards

/* Moving Pearson Correlation */
/* SK 13FEB98 - changed this from macro to XPL func, changed calcualtion to
deal properly with NAs. */

==========================
These are the moving average functions
MOVAVG(series, points, rampflag, sum_only, type, factor, perform_on, lag,
lag_amt)
PURPOSE: "Smoothes" a series by averaging around each point.
series A window or variable reference.
points Integer. The number of points to average as the series is processed.
rampflag (Optional). Integer flag. Method of calculating first n points in
the series. Options are: 0 - show "ramp-in" edge of moving average; 1 -
Average by n, even for first n points (default).
sum_only (Optional). Integer flag, which if set to 1, or TRUE, produces a
moving sum (rather than a moving average).
type (Optional). Type of moving average to perform, where options are: 0 -
Normal (default); 1 - Modified ; 2 - Weighted; 3 - Exponential; 4 - Hamming;
5 - Hanning ; 6 - Kaiser; 7 - Modified Exponential.
factor (Optional). If type is 3 (exponential), the decay factor. If type
is 0 or 1, factor is ignored. Options are: 0..1 - FIR function is
used; -1..0 - IIR function is used.
perform_on (Optional). Integer. If input series consists of multiple
columns (e.g., CHLO bars), this number indicates on which series to perform
the moving average. Defaults to 0, i.e., the first valid series.
lag (Optional). Integer flag. Options are: 1 - lag the moving average; 0 -
do not lag (default).
lag_amt (Optional). If lag is 1, or TRUE, the amount by which to lag the
moving average. If lag_amt is set to 0, then the moving average is lagged by
1/2 of the length of the input series.
