Calculate portfolio value per asset

I have next assets portfolio transactions table:

 Also I have:

• Calendar table (universal DateDim)
• Stock table (stock prices table with DATE, ASSET-ID, PRICE columns). So I have one PRICE column for all assets.
• [Stoсk Price CUR] measure that calculate actual stock price without data gaps

I need a measure that calculate my portfolio total value for each date (without date gaps).

I'm trying to modeling a next algorytm

1. Calculate actual balance for each asset [measure]
   Here I use LASTNONBLANK formula
   
   

   Balance WoG = 
   VAR d =
       SELECTEDVALUE ( 'Calendar'[Date] )
   RETURN
       CALCULATE (
           LASTNONBLANK(split[end-balance];1);
           split[Date] <= d;
           CROSSFILTER ( 'Calendar'[Date]; split[date]; NONE )
       )

2. Calculate actual value for each asset [measure]

Here I'm trying to use that formula:

Asset Value = 
    CALCULATE([Balance WoG]*[Stock Price CUR])

That works fine only then I use asset-id as Legend on my chart (see screenshot), but I inderstand, that I need something more savvy

3. Sum all assets value [measure]
Can't understand how to solve it
