Answer 1

Small example:

Formula in D1:

=SUMPRODUCT(SUBTOTAL(3,OFFSET(B2:B7,ROW(B2:B7)-ROW(B2),0,1)),--(B2:B7=1))

Formula in F1:

=SUMPRODUCT(SUBTOTAL(3,OFFSET(B2:B7,ROW(B2:B7)-ROW(B2),0,1)),--(B2:B7=-1))

Result

If you can't use the above because of error values as per your comment, one thing you could do is to build an array of values with some IF statements like so:

=SUMPRODUCT(SUBTOTAL(3,OFFSET(B2:B7,ROW(B2:B7)-ROW(B2),0,1)),IF(ISNUMBER(B2:B7),IF(B2:B7=1,1),0))

and:

=SUMPRODUCT(SUBTOTAL(3,OFFSET(B2:B7,ROW(B2:B7)-ROW(B2),0,1)),IF(ISNUMBER(B2:B7),IF(B2:B7=-1,1),0))

Both formula entered as arrayformula!
