$SPX shorter term Exponential trendlines

This chart is one of the sources for my call yesterday that the market might falter here...You can see which trendline has held so far, it's highlighted. These trendlines are generated from the start and end points of the October 2007 through March 2009 decline...this is a shorter term basis then some of the other ones I've published here. They can be violated, but I give them the benefit of the doubt until they are.
