I am looking for a formula to place in ColC of Table A that will look at
Table B, Find the match for value in ColB Symbol, and if ColA in Table A is
"Buy", find "Sell" in ColA of Table B (similar if Table A is "Sell", Table B
match needs to be "Buy". If the 2 conditions are met, sum the values in ColC
of Table B.

Hope I explained my problem ok.

Thank you in advance.

Assumptions:

A1:B8 contains Table A

E1:G18 contains Table B

Formula:

C2, copied down:

=SUMPRODUCT(--(E$2:E$18=IF(A2="Buy","Sell",IF(A2="Sell","Buy"))),--(F$2:F
$18=B2),G$2:G$18)

Hope this helps!
