Colin,
What you suggest is a different kettle of fish entirely.
I was looking to arbitrage the small difference in the returns of forex spreadbets and real forex transactions. Although the differences are real, they are very small and easily outweighed by the cost of financing the positions on margin (and if you don't do it on margin then the returns are tiny - 2%).
What you are suggesting is the old "short the rolling cash and go long on the quarterly". I'm fairly sure that there isn't any hidden value between these instruments and one would just lose out to the spread in the long run. It is also a little harder to do the maths to work out if it would work or not.
John.
