You had asked:

Uh, no, that's not even close to correct.  But, yes, your TradeStation work
seems fine.  My point is that I do not believe that a polynomial in any way
"predicts" the market.  And, I sure don't want to take responsibility for
anyone's believing that it has predicitve value.  This is not to say that
you or anyone else could not come up with a way to use it as a predictor.
But, you definitely shouldn't conclude from my simple indicator that we
will see "sharply lower prices for the three days after the 18th."

All that I believe you can say from the chart attached to your message is
that the trend had been downward leading into Friday, and that a polynomial
projection would continue to point downward.  Is that a "prediction"?  Not
in my book.

Hope that helps clarify things
