Transactions made yesterday 05/21/07
-2 P13/7 0.75 $150-1.5=$148.5
I've got $148.5 for that trade (after commission of $1.5)
+4 C16/8 1.55 $-620-4.0-6.9=$-630.9
I had to pay $630.90 for that trade, because there have been commission of $4.0 (4*$1 and cancellation fees of $6.9).
Motivation for that transactions was to bring the Vix portfolio into a balance and protect against a rising Vix. Since the Vix August future is slower than the Vix June Future it's not a 100% hedge.
I have choosen the August vs. the July because the 'term structure' gives better values for the August-July than for the July-June.

I would get 79.29 minus spread minus commissions, if I'd decide to close the portfolio.
A last remark about the bought Calls C16/8
I payed $620 and according settlement values I'd only get $550.53 (before commissions/spread). That's an immediate loss of 11.2% ($69.47).
