At 11:17 a.m. CT, Defendants turned the Layering Algorithm on for more than two consecutive hours, until 1 :40 p.m. CT. During this cycle, Defendants utilized the Layering Algorithm to place five orders, totaling 3,000 contracts. A sixth order was added at around 1:13 p.m. CT, increasing the total to 3,600 contracts.... Between 11:17 a.m. CT and 1:40 p.m. CT, Defendants' actions contributed to an extreme order book imbalance in the E-mini S&P market.
