Oil price trading case nears end

High-frequency trading firm Optiver Holding has set aside $19.3m to deal with one of the biggest oil-manipulation cases ever brought by the US futures regulator, according to a copy of the private firm's annual report. The three-year-long case, brought by the US Commodity Futures Trading Commission (CFTC) against the Amsterdam-based firm, may now be heading for settlement. The second of two August mediation sessions took place in New York this week.
