need rolling standard deviations, annualised return etc

[yipdog]

Hi I am trying to build a table to track certain fund performance and calculate their rolling standard deviations, annualised return etc, however the release date of these data differ between each fund, my formula is constructed to find the first non zero number in the data row then scan to the right in order to calculate the metrics needed.

Can someone help with my formula aha, i am quite frustrated!


An example is to calculate the 1 year rolling standard deviation [The formula below aint working]

=IFERROR(STDEV(OFFSET(U13,0,MAX(IF(NOT(ISBLANK(U13:UD13)),COLUMN(U13:UD13)-COLUMN(U13),0)),1,-12)),"plz fix")
