Subtract daily sold amounts from running total

[Bondeuz]

Hi,

I am looking for a dax formula to subtract the daily sold amounts from the running total to predict a date were the inventory will be empty.

Here is my current visual objects.

Here is my expectation of this formula, drawn by the purple line. For the line to start at the last transaction date then subtract the daily sold amounts and to show visually when the stock will be empty.

For information my measurments looks like this.

Avail. Inv. = BON_Items[InventoryField]-(BON_Items[Y365_Qty_on_Sales_Order]-BON_Items[Y365_Qty_on_Component_Lines])

ArtTransSumABS = SUM(Yellow_ItemLedgerEntryBI[QuantityABS])

DaysBetween = DATEDIFF(FIRSTDATE(Yellow_ItemLedgerEntryBI[PostingDate]),LASTDATE(Yellow_ItemLedgerEntryBI[PostingDate]),DAY)

Total Quant. Trans. Div by Total Trans. Days = DIVIDE([ArtTransSumABS],[DaysBetween])

For my running total formula its made from the quick measurments.

Running Total for Quantity in Date = 
CALCULATE(
    SUM(Yellow_ItemLedgerEntryBI[Quantity]),
    FILTER(
        ALLSELECTED('Date'[Date]),
        ISONORAFTER('Date'[Date], MAX('Date'[Date]), DESC)
    )
)
