The anti-spoofing statute criminalises the entry of bids or offers in the market with the intention of cancelling them before they are traded. At trial, US federal prosecutors successfully argued that Mr. Coscia’s trading algorithm repeatedly placed large “bait” orders for futures contracts that he had no intention of trading. These large orders nonetheless created a brief illusion of market activity - an illusion that moved prices and enabled his algorithm to fill smaller orders from which he profited. Over ten weeks, his “bait and switch scheme” netted Mr. Coscia roughly US$1.4m in profits across the CME Group, Inc. (CME) exchanges in Chicago and New York and the London-based Intercontinental Exchange (ICE) on which he traded.
