The USD appears to be close to the top range of it's own channel.
Given the steadfast relation between USD and SPX (inverse that is), that would put a damper on SPX downward motion.
But SPX is at an important PRS channel line also.
Euro seems to have "broke the mold" but the Forex also is gamed more than equities.
I do not believe "baked in the cake" thinking / promotion. The greek swans will eventually come home to roost, as with the Spaniard's own special brand of goose to be cooked.
It won't matter, until it matters. It is impossible to trade this market fundamentally. The casino version, the concentration of money and trading information has made it so.
For now, the strongest stuff I have says short ES short Euro.
