Count of day since positive

[chewBAKA1]

Hello everyone,

I've got a table with symbol(X,XX,XXX),profit(-1,10,56,..),date(YYYY/MM/DD hh:mm:ss) DATA.

I would like to add a kpi that show a counter of day since the sum of all profit is positif (like a "no accident in this plant since X day").

is it possible?

thank you.
