"According to Eric Hunsader of Nanex, there were 179 "mini flash crashes" during the first 15 minutes of trading, which is the most since the Knight Capital Group fiasco in August 2012. Additionally, Hunsader reports that there were 68 trades in the S&P e-mini that moved that key futures contract 3 or more ticks. And Treasury futures, too, moved sharply as a result of low liquidity." - Eric - Final Countdown
