As Dow futures opened ahead of this evening's China open (after being closed since Wednesday), it appears someone (or something) decided it was time to test down 100 points to Friday's pre-ramp lows. Of course that mini-flash-crash has now been followed - since stops were run - with a 140 point ripfest, we assume gunning for the stops just above Friday's late-day highs... Other moves of note ahead of the China open are a sizable surge in Bitcoin (looming Yuan devaluation?) Charts: Bloomberg and Bitcoinwisdom.com
