Someone decided that 1436ET was the perfect time to buy $1bn worth of S&P 500 futures (10k contracts) in 1 second (and $1.8 billion in that minute)... this flush of volume is the largest minute of the day and lifted all equity indices and ETFs in one magical move. As a result of the order, bonds rallied even as and VIX is higher on the day.
14:36:20 - that was 10K eMini's in a second + $64M of $SPY [2]
