1) g20 consensus - not to devalue currency, us included -> dollar will not inflate as much as hoped -> commodity drops
2) opx next weekend
3) china stock market had a major down day on 1), speculation on further interest hike, and tax on capital gain/transaction
all 3 caused today's drop, watch china market on sunday night, watch the dollar/uup especially monday morning, to see if this retreat is going anywhere...
