Taking Another Swing at a Corn Spread Short

We missed on our first Corn spread short, but another excellent opportunity has presented itself. The Corn (U19-H20) calendar spread has profited 14 of the past 15 years when sold on 7/20 and bought on 8/13. The profit to draw-down ratio is huge at 469% and the best profit versus worst loss is over 18x. On Friday, I will be selling the Corn (U19-H20) calendar spread at or near the Thursday close.
