My intentions are not to be negative, in fact I try to be unemotional, and I certainly wouldn't call the crisis brewing in China as irrelevant. The market tends to be predictive, and I was simply providing info on what could have been the problem on Friday night. China's central bank is trying to manage a weakening yuan, which is shrinking their foreign currency reserves at an alarming rate. Fundamentally this will have a negative effect on all markets.
For context, from FXCM:
