Dynamic Weighted Moving Average

**Sthlm** · 10-21-2013, 08:56 AM

Hi, Ive run into a bit of a problem trying to achieve a dynamic weighted moving average.

Is what I'm using in a lot of rows, so updating is becoming a bit of a hassle.
=SUMPRODUCT(BF8:BI8;{1\2\3\4})/10

So I'd like it be dynamic, always using the last 4 filled cells in that row in the formula.

What i've got so far is:
=SUMPRODUCT(OFFSET(INDIRECT(ADDRESS(ROW();9));COUNT(INDIRECT(ADDRESS(ROW();9)&":"&ADDRESS(ROW();300)))-4;

;{1\2\3\4})/10

And it's not working. Do you have an idea how i can solve this issue?

Try this version for row 8

=SUMPRODUCT(OFFSET(8:8;0;MATCH(9.99E+307;8:8)-4;1;4);{1\2\3\4})/10

Thanks that did the trick! I had to change it to 9,99+307 for it work. Regional issue
