I appreciate the info on the energies.  I am familiar with strips trading as
you can easily trade short rate bundles. The backwardation/contango problem
combined with thin back months is the main problem.  Yes, this problem does
occasionally occur with interest rates but the ease of getting prices on and
trading 360 day money takes care of that.  BTW - do they trade energies as
strips/bundles and if so how deep and wide are the markets.
I have spoken with other ctas regarding their approach and so far what most
use seems to be a shorter term backadjusted with an overlap period - for
example, corn from 88 - 92 with the next snapshot covering 90 - 94.  Would
still appreciate any further comments
