However, the grains across the board have gone ballistic and prices have broken out of their recent tight trading range. Perhaps this time, prices won't collapse tomorrow in a continuation of the see-saw price action of the past few days. Overnight, grains prices collapsed again, reversing direction from yesterday's day-time price behavior. However, today, grain prices have reversed again and moved substantially higher. The grain analysts were generally expecting lower prices this morning, so this is a surprise to everyone.
