You would likely get your best entry on the open if you want to hedge XLF via a shorter term XLF short or via some other finanshill/bank derivative. For my call for the dollar to be bullish I want to see it sell of now from here...I figure the dollar will run with the other safe have >>> U.S. govmint debt. If teh dollarr sells off early I would "guess" that XLF will rally. The only thing that can actually keep you from this hedge is if XLF gaps down on the open. Then I would avoid the trade in ALL directions til it settles out. :-) Here's the king...the dollah via UUP.

Upside target of 24.75, when the dollar begins to run. ...which might be delayed for at least a couple of days depending on tomorrow's open. I gave a comlete overview of the dollar, VIX, and QQQ's here...
