Derek,
The psuedo code logic you need is something like:
If S&P < its
200 MA
then set PositionScore of bond funds to 999 (very high value)
else set PostionScore normally
If your worst held rank is x, then include at least x number of bond funds in your universe to force the rankings of all other securities below the worst held rank cut off.
This will work for backtesting purposes. In real time, then you would only need to buy 1 bond fund instead of x.
