wednesdays wriddle

not so much of a riddle but more of a thread change.

I have a trend change possibly this Friday, and it coincides with the US GDP figures which the world is waiting for with baited breath. . Why ?
144 trad days from the 6/1/09 highs and 144 cal days from the 10/3/09 lows.
So on the basis of this, I am guessing the market wont like the figures and sell off down to the 7/8/09 date which some have been looking at, incl meself.

so if someone has the answer to my jimmy wriddle i'd be happy...lol
