How do I cumulate this?

[Tantanarsenal]

Hi, 

I am a beginner at DAX and could need some help...

I have created this code: 

NrOfNegative= CALCULATE (
    DISTINCTCOUNT ( Total[ReferencePeriod] ),
    FILTER ( Total, Total[ChangeDAX] < 0 )
)

Where I got the number of months where the change is negative. However, I would like it to cumulate and I can't seem to do that...

Could someone please help me?

@Tantanarsenal ,

Try a new measure on top of this using date table

Cumm = CALCULATE(SUMX(values('Date'[date]), [NrOfNegative]),filter(all('Date'),'Date'[date] <=max('Date'[date])))

Running Total/ Cumulative:

You can also consider Window function
