You are leaving out something because your numbers don't make sense. Don't know how important this is.
if you put in 10K and had a realized profit of 3K you should have cash of 13K. To have a negative cash of 7K would mean either you withdrew cash and/or you bought securities of about 20K that haven't been sold and/or you had a loss of 17K or something else. We don't know what you are trading. This may be important if you're trading commodities and/or are doing hedging transactions. The reporting may not be as simple as reporting the profit/loss on closed positions.
