Below is daily candle stick chart portraying the price action for the JUL16WMAZ contract.  The contract price slumped sharply lower at the start of yesterday’s session on the back of news, late last week, that two ships carrying cargo of white corn, imported from the U.S, has made its way to South Africa with further talk that the production of U.S. white corn this year would will be sufficient to aid South African supply shortage, according to an article in the Landbouweekblad.  Traders look ahead at the April WASDE report released later this afternoon.
