Calculating a factor
Hi ZodtePt ,
Depending on your requirements description, you want to implement logic that implements loop iteration multiplication by referencing the value of the "factor" on the previous line, right? The logic of the first line should be derived like this, right?
100*(0.1365+1)^((42-0)/252)-1
If this is the case, DAX can not implement the loop iteration multiplication logic you want to get, I recommend that you use the For loop in Python to implement this logic, convenient and efficient, and then use Python to implement this logic, you can in turn try to use PBI desktop's Python data source connector to connect to this processed data, and continue to create the corresponding visual according to your needs:

Hi Anonymous, thanks for your help!
as I mentioned the idea is to be able to create a column called FATOR where the result needs to follow this logic:
FATOR = "Previous Factor" * ("Taxa CDI Deslocada"+1)^(("Dias úteis" - "Dias Úteis Deslocada")/252)-1
Since there is no "Previous Factor" for the first row (because it's the first one), the logic for the FATOR in the first row should be:
FATOR = 100 * ("Taxa CDI Deslocada"+1)^(("Dias úteis" - "Dias Úteis Deslocada")/252)-1
for all other rows, the logic is: the FATOR from row "n" has as "Previous Factor" the FATOR from row "n-1"
FATOR(n) = FATOR(n-1) * (Taxa CDI Deslocada(n)+1)^((Dias úteis(n) - Dias Úteis Deslocada(n))/252)-1
n=row number
for the first row FATOR(n-1) = 100
this helped?
