His three-year prison term is to be followed by two years of supervised release.
Coscia's sentencing follows a ruling Tuesday in a spoofing lawsuit brought by the Commodity Futures Trading Commission allowing a defendant to continue trading before a trial set for January.
Igor Oystacher, of 3Red Trading, was accused by the CFTC of continuing illegal trades even after it sued him.
A jury deliberated for one hour before finding Coscia guilty of six spoofing counts and six fraud counts. He was the first person tried under a provision of the 2010 Dodd-Frank Act that made it illegal to manipulate prices by placing orders without intending to execute them.
Testimony during the trial showed that Coscia, like many high frequency traders, used an algorithm to place, cancel and execute orders. Coscia testified that he intended to execute all of his orders at the time he placed them.
He said he wasn't aware of the provision of the Dodd-Frank Act and his lawyers argued in court filings that the law was unconstitutional.
Prosecutors presented trading data from the Chicago Mercantile Exchange and the ICE Futures Europe exchange showing that Coscia placed orders that were much larger than any others trading at the same time and also that he canceled those orders much more frequently.
During the trial, prosecutors focused on six transactions in the gold, euro, soybean meal, soybean oil, British pound, and copper futures markets. In total, these trades resulted in a profit of $1,070, according to testimony. Coscia conducted thousands of such trades, prosecutors told jurors.
