Measure that adjusts with filters

[Anonymous]

Hey guys, 

In my initial data, I have a bet account number and a row for every day along with the sport that they bet on and a few more dimensions, I then have a few numerical measures such as margin after specials (above).

Now when I apply different filters, Power BI will sum up the values to give the correct number for the filters I choose.

The issue I have is that I need to find a count of the account numbers that sit in a negative balance. For that I need to create a measure that sums the margin for every account number and that number will change depending on the filters applied.

Essentially the measure should store whatever number is connected to the account number in the table above.

Can anybody help me ?

Try something like the below:

Measure = COUNTROWS(FILTER(ADDCOLUMNS(VALUES(Table[Bet_Account_Num]), "Margin", CALCULATE(SUM(Table[Margin_After_Specials])), [Margin] < 0)
