Power Query Custom Column Formula

[KaiA]

Dear Aflatoon,

I moved your code to the end of my code a second time (I tried before but must have done something wrong), and now it worked!

This is just great - many thanks, this is very much appreciated.

So if I rate this thread, this is how I rate your support, right?

Is there a way to modifie the code so that the calculation starts at the end of the table (oldest date)? The top of the table contains the most recent date. So what I need is actually the other way around. I just tried "then [NAV] / PreviousRows{[Index] + 1}" instead then [NAV] / PreviousRows{[Index] - 1} and it seems to work.

Thanks,
Kai
