A market sell signal from a quantitative model

I have posted a few times back in August about my market quantitative model. The model has just generated a sell signal. This is the first sell signal since April's buy signal (see the attached figure http://tinypic.com/impch4.jpg). It has a very high probability that when the next buy signal is generated, the SP500 will be lower than what is today.

Welcome back!  And hope see your posts in the future.
