Thanks for the link to the PDF.
I used CME credit ratios to choose the 3:2 one: http://www.cmegroup.com/clearing/margins/inters.html#e=CME&a=AGRICULTURE&p=FC.
It is true that this spread was ill conceived considering the expiries I chose. I later read the the CME pdf and discovered a more proper way to trade cattle feeding spreads.
Anyway, I didn't check but I don't think any other ratio or expiry choice would have transformed it into a winning trade. This strength of feeders relative to cattle was just counterseasonal.
