Here's another thing I noticed on the Trading History web page. All of the
transactions are listed in terms of Y claims, even for 'short sales', e.g., if
you buy an N claim at 80, it is listed as a sale of a yes at 20, e.g., B -1 @ 20.
However, when an N claim is judged, the final transaction is listed as a buy at
the N claim price, which is not consistent. Here is an example:

/ Date Buy Price Held Balance BEP/
2005/04/18 -5 @ 10 -5 -4.50 0.10
2005/04/19 -10 @ 15 -15 -13.00 0.13
2005/08/23 15 @ 100 0 2.00 PROFIT
Cost: $ 13.00 ; Income: $ 15.00 ; Held Value: $ 0.00 Return: 15.38%

First, Y claims were sold (N claims bought), resulting in a negative number of Y
claims. Then when the Y claim did not come true it was judged at 0. The last
transaction above represents the judging and should read B 15 @ 0 if written in
terms of a Y claim, or S 15 N @ 100. Instead it is listed as a B 15 @ 100.

There is a similar problem when an N claim is judged at 0. An example:

/ Date Buy Price Held Balance BEP/
2001/11/15 -5 @ 72 -5 -1.40 0.72
2002/01/15 5 @ 0 0 -1.40 LOSS
Cost: $ 1.40 ; Income: $ 0.00 ; Held Value: $ 0.00 Return: -100.00%

Here the Y claim was judged true, and the result at judging should be B 5 @ 100
or S 5 N @ 0, but it is listed as B 5 @ 0.

I know this is not a big problem and it doesn't affect the scoring, but it bugs me,
and makes reading the listings more difficult. Is an easy fix possible?

BTW, when a Y claim is judged, the final entry is written in terms of a Y claim,
so it is consistent:

/ Date Buy Price Held Balance BEP/
1999/01/07 1 @ 12 1 -0.12 0.12
2001/01/03 -1 @ 0 0 -0.12 LOSS
Cost: $ 0.12 ; Income: $ 0.00 ; Held Value: $ 0.00 Return: -100.00%

/ Date Buy Price Held Balance BEP/
1998/10/29 50 @ 94 50 -47.00 0.94
1998/10/29 55 @ 94 105 -98.70 0.94
1998/11/07 -105 @ 100 0 6.30 PROFIT
Cost: $ 98.70 ; Income: $ 105.00 ; Held Value: $ 0.00 Return: 6.38%
