2. Commodities trader Navinder Singh Sarao was arrested at his home in London in connection with the 2010 "Flash Crash" that shook global markets. On May 6, 2010, the S&P 500 mysteriously plunged 9% and the Dow fell about 1,000 points. According to the CTFC complaint, Sarao used a "layering algorithm" to push out multiple large sell orders that would modify themselves to move with S&P 500 E-Minis futures prices. Allegedly, the layers of orders would increase the spread between the bid and the asking price so that other traders would stay away from the best price. Sarao would then cancel the sell orders, according to the complaint.
