Thanks in advance.

Thank you @micheledenardi  for the reply, i have read the article, it's interesting, however i can't understand the meaning of this formula:  

Max(TOTAL {<date={"*/$(=Year(Max(date)-1))"}>} Aggr(If(date=Max(TOTAL <id_invested> date,2), Max(position)),id_invested,date))

can you help by interpreting the meaning of   {<date={"*/$(=Year(Max(date)-1))"}>} here please?

Thank you.

Not sure they can be used together since * means Intersection and / means Symmetric Difference.

 {<date={"*$(=Year(Max(date)-1))"}>}  this returns all "date" where the year is equal to the year of Max(date)-1 according to current selections.

 {<date={"/$(=Year(Max(date)-1))"}>}  this returns all "date" where the year is not equal to the year of Max(date)-1 and not equal to current selections
