Get average stock price in Google Sheets from a list

Question

I'm trying to get average stock prices from a dynamic list.

In my example, I've made a bought stocks in a few different days. And I've sold some of them (not all). So, I have some stocks available that I want to find out the average price:

How to get an average price from stocks not sold, from the earlier to the latest date without changing manually the list?

Manually, the result must be: $19,82

I've built an example sheet.

Thanks! Any help will be appreciated!

Answer 1

用：

=AVERAGE.WEIGHTED(FILTER(E3:E6; B3:B6="buy"); FILTER(D3:D6; B3:B6="buy"))

更新1：

=INDEX(AVERAGE.WEIGHTED(FILTER(E3:E6; B3:B6="buy"); FILTER(D3:D6; B3:B6="buy")-
 {SEQUENCE(COUNTIF(B3:B6; "buy")-1; 1; 0; 0); FILTER(D3:D6; B3:B6="sell")}))

更新2：

=ARRAYFORMULA(AVERAGE.WEIGHTED(FILTER(E3:E6; B3:B6="buy"); IF(0<FILTER(D3:D6; B3:B6="buy")+
 IF(0>MMULT(TRANSPOSE((SEQUENCE(COUNTA(FILTER(D3:D6; B3:B6="buy")))>=
 TRANSPOSE(SEQUENCE(COUNTA(FILTER(D3:D6; B3:B6="buy")))))*
 QUERY({FILTER(D3:D6; B3:B6="buy");-SUM(FILTER(D3:D6; B3:B6="sell"))}; "offset 1"; 0)); 
 SIGN(SEQUENCE(COUNTA(FILTER(D3:D6; B3:B6="buy"))))); 
 MMULT(TRANSPOSE((SEQUENCE(COUNTA(FILTER(D3:D6; B3:B6="buy")))>=
 TRANSPOSE(SEQUENCE(COUNTA(FILTER(D3:D6; B3:B6="buy")))))*
 QUERY({FILTER(D3:D6; B3:B6="buy");-SUM(FILTER(D3:D6; B3:B6="sell"))}; "offset 1"; 0)); 
 SIGN(SEQUENCE(COUNTA(FILTER(D3:D6; B3:B6="buy"))))); 0); FILTER(D3:D6; B3:B6="buy")+
 IF(0>MMULT(TRANSPOSE((SEQUENCE(COUNTA(FILTER(D3:D6; B3:B6="buy")))>=
 TRANSPOSE(SEQUENCE(COUNTA(FILTER(D3:D6; B3:B6="buy")))))*
 QUERY({FILTER(D3:D6; B3:B6="buy");-SUM(FILTER(D3:D6; B3:B6="sell"))}; "offset 1"; 0)); 
 SIGN(SEQUENCE(COUNTA(FILTER(D3:D6; B3:B6="buy"))))); 
 MMULT(TRANSPOSE((SEQUENCE(COUNTA(FILTER(D3:D6; B3:B6="buy")))>=
 TRANSPOSE(SEQUENCE(COUNTA(FILTER(D3:D6; B3:B6="buy")))))*
 QUERY({FILTER(D3:D6; B3:B6="buy");-SUM(FILTER(D3:D6; B3:B6="sell"))}; "offset 1"; 0)); 
 SIGN(SEQUENCE(COUNTA(FILTER(D3:D6; B3:B6="buy"))))); 0); 0)))
