Hi phil, thanks, running through ur spreads, Sunday breakout gives a sharpe ratio of 1.2 (since 04), and actually, comparable to cowabunga (since 08, which i backtested). But we know which one gives us more time to take our holidays!
by comparison, S&P 100 yr historical sharpe is 0.4, and even Madoff based on my readings "window dressed" a sharpe of 2.5 (with 11% return, so extraordinarily low volatility beyond realms of possibility).
caveat is that don't rely on my figures and run them yourselvs, as sharpe fluctuated over the 4 yrs depending on which period you took.

Ok, i've calculated the sharpe ratios for all the years:
05 - 1.5 (excellent, could maybe get into nominated for a hedge fund award...)
06 - 1.4
07 - 0.94
08- 1.5
09- 0.78 (a few more months data to come, implying we ought to see better results in coming months to boost sharpe to 'normal' levels?!)

Also, I don't remember if I mentioned this or not but back when Orpips and I were discussing backtesting results I found some backtesting errors I made in 2008. Apparently while backtesting mid 2008 I switched to a 1H chart to look at something and forgot to switch back for a few months!! So what I thought was the Sunday candle was really only half of it and my stoplosses were smaller than they should have been!! I corrected the problem on the new spreadsheet, and it changed the systems backtesting results over the 5 year period to be about 400 pips lower (7500 instead of 7900).
It's a small mistake that doesn't really change the systems profitability, but I thought I should point it out in case anyone is using the old excel file to help with their own backtesting.
