“Purchasers of platinum, palladium and futures contracts for the metals accused the defendants of conspiring from Jan. 1, 2008 to Nov. 30, 2014 to rig the twice-daily platinum and palladium “fixings” by sharing customer data, front-running expected price moves, and placing bogus “spoof” orders.

Lawyers for the purchasers called the settlement an “excellent” result that was fair, reasonable and adequate.”
