I went long off on Sunday afternoon and scaled in-and-out all day Monday.

From Ninjatrader:
Average Price 1356.41666666667
Trades:
Buy     1       1358.00 7/1/2012  4:45:29 PM    Entry   1L
Buy     1       1354.50 7/1/2012  5:16:02 PM    Entry   2L
Sell    1       1358.25 7/2/2012  1:14:55 AM    Exit    1L
Buy     1       1356.75 7/2/2012  7:00:00 AM    Entry   2L
Sell    1       1357.50 7/2/2012 12:35:05 PM    Exit    1L

I prefer to think of it this way.
The cost basis for the one contract I have left is:
1358.00 + 1354.50 - 1358.25 + 1356.75 - 1357.50 = 1353.50

So, I'm effectively long 1 contract from 1353.50 at the end of the trading day.
