Note the May Corn chart. See the tight several bars just back over support and riding the 20ema since the strong rebound back up again. Tight patterns like this tend to be explosive when the 'decision' on direction that is holding this pattern together is made. An option Strangle would be the ticket here I would think. Or a Straddle and dump the losing side on a breakout. Expect some fireworks in any case and soon.
