Well, the last hour has definitely been a magic carpet ride - congratulations, BTW! It's starting to look pretty good - $USD may be putting in a topping candle right at the apex of a bearish rising wedge. If so, that would be good for all equities - especially PMs and commodity - based stocks.
Still, regarding HGU, I would be tempted to sell a third or half just to lock in some profits, but I'd let the rest ride for another day or 2.
