Paper Trade Tally for the week of July 23-27

This is the first week we started a tally so please let me know of any suggestions you might have.
I am calling this system the rolling index. You will see why at the end of this update. The index started at 10,000.

Rules:
We started this week with $10,000.
We can have at most 10 positions, each having close to a $1000 dollar investment. At first, I was going to buy exactly $1000 worth of stock but you can't buy fractions of stocks, so I have rounded all fractions of stock upward in trying to keep this paper trading system as realistic as possible.
All transactions have $10 commissions.

Stopped Out
1) AMR 28.30. Out at 26.04. Loss of 1.90 x 35.33shares = -67.13
2) GLW 26.87. Out at 24.72. Loss of 2.15 x 37.22shares= -80.03
TOTAL REALIZED LOSS FOR WEEK IS 147.16+20 commissions=167.16
