"I don't have a loss, I have a gain. "
of course. My apologies for misreading your question hastily.
You don't have a cost of trade, column (d) because you haven't closed your short position yet,
You don't have a Date Acquired either, because Date Acquired is the date you close your short sale.
Moreover, you don't have an unrecognized gain column (e), because your positions were all marked to market.
