Assuming your tabulation table Total Spent for A is cell B13, and so forth...
Type the following in B13:
=SUMPRODUCT(--(Trans="Buy"),--(UnitType=$A13),(Qty)*(UnitPrice))
And the follinwg ni C13:
=SUMPRODUCT(--(Trans="Sell"),--(UnitType=$A13),(Qty)*(UnitPrice))

Trans is the range of Buy/Sell
UnitType is the range of A/B/C/D, etc.
Qty is the range of quantitites for each
UnitPrice is the buy or sell value per unit.
