Oil, stock trading spiked before Trump's Iran remarks

Between 1049 GMT and 1050 GMT, 734 oil contracts changed hands, and in the next minute that number surged to 2,168 -- 16 times higher than the average observed through the day up to that time. Bloomberg estimated the value of oil contracts that changed hands between 1049 and 1050 GMT was $650 million. At 1105 GMT, Trump stepped back from a threat to attack Iranian energy sites, citing "very good" talks to end the war in a social media post. The statement sent crude prices plunging more than 14 percent in a fresh burst of trading activity.
