Inventory Calculation_DAX help

I need help in inventory calculation,
Example: I have received stock on 1st, 2nd, and 3rd and the stock is 10 shirts per day and total stock is 30 now 
and on 4th 15 shirts sold 

desired result: the sold count should deduct fromn first in date(the count sold is 15 on 4th so 10 should be decuted from 1st date and 5 shoud be deducted on 2nd)
and in the same way when 7 shirts sold on 5th date then 5 deducted from 2nd date (remaining in 2nd date) and 2 should deduct from 3rd date
 

I got answer for this,

Measure =

  VAR __Date = MAX('Table'[Date])

  VAR __InTable = FILTER(ALL('Table'),[New Stock] <> BLANK())

  VAR __OutTable = FILTER(ALL('Table'),[Stock out] <> BLANK())

  VAR __Out = SUMX(__OutTable,[Stock out])

  VAR __ResultTable =

    ADDCOLUMNS(

      ADDCOLUMNS(

        __InTable,

        "__RunningTotal",SUMX(FILTER(__InTable,[Date]<=__Date),[New Stock])

      ),

      "__WhileLoop",[__RunningTotal] - __Out

    )

  VAR __Result = MAXX(FILTER(__ResultTable,[Date] = __Date),[__WhileLoop])

RETURN

  IF(__Result <= 0,0,__Result)

but I have another question

Now I need help in inventory calculation(help me in modifing above DAX code)) for individual branch.
Example: the inventory deduction should be done on specific branch

Example:
