I have a formula that has a variable "x" calculated 8 days ago....this I know how to do.

I then want to use "x" as a constant in the formula over the last 7 days.

Here is part of the formula syntax:

If( Defined, Signalb, DerivedAvg - x)

The formula plots "DerivedAvg - x" over the last 8 days, otherwise it plots Signalb. As it stands now, the formula calculates "x" from 8-days ago and ONLY applies it to Today. I want "x" to be applied to Today AND the 7 preceding days too. So each new day, a new value of "x" is calculated and used in the formula both Today And over the past 7 Days.

Thank's,

Dennis
