One could have done even better than the pure system had you anticipated that the negative cross would come after the drop started and the S&P broke below the 50 sma.

400 point drop on s&p in last 10 trading days.
The system said to short on the 2 crosses which would have been right on 350 s&p points of the 400 so far.
Short around 4300.
Short again 4109.
