By the charts, if one binned grain(say corn) off the combine every fall, waiting for a better price, what is the longest period that it would have to have been stored to at least get back to even?  Throw out the raging bull market years, since that is easy to figure out, only in flat or long term downtrending markets such as this.  Is it months, years, decades?  In my short lifetime, it seems that there is always an opportunity to do better than breakeven within a couple of crop years, not considering the opportunity cost and storage etc.  Are the odds against storage?
