weather markets DANIEL HILLER 06/29/2012 @ 1:37pm with the advent of the outside spec money from different sources, the old rules for weather markets may not hold any more. that being said I look at the number of market days of weather markets to give me timing to start buying puts and selling out of the money calls as well as taking profits. Yes selling a crop is taking a profits when the prices are above cost of production. I am a new farmer in dry nw Ohio and also a retired commodity broker. there is a lot less risk farming and it is more fun.
