The Black Box

[exp]

wld, good point for sure...and yet certain patterns which regularly occurred for the past 3 years should continue to occur for portions of my system to work well...
and when these patterns change i look for reasons and possible adjustments...
i keep looking at 1998-1999 ndx charts and i see different patterns during that period...
the problem in general is of course that many patterns did not occur 30 or even 18 times in 2000-2002 so they are statistically suspect...
