Thought I'd pop in and share some observations FWIW. Sorry if any of them have been mentioned already.
With respect to DOW;
12/3/2003 to 12/3/2010 = 2557 days
14/1/2000 to 12/3/2010 = 2557 trading days

9Lives mentioned 512 days and 1.618 extension of it.
The prior top was
17/7/2007 to 6/3/2009 = 598 days x 1.618 = 968
17/7/2007 + 968 days = 11/3/2010

from the low on 14/1/1991 to 15/3/2010 = 7000 days

From 9/8/1982 low to 15/3/2010 = 1440 weeks

Gann's great square was 144 x 144 = 20736
3/9/1929 to 16/3/2010 = 20720 trading days (according to my data) - nearly there.

8/7/1932 low to 19/3/2010 = 20000 trading days.(according to my data)

Are we on the verge of a major top - possibly. But then again ....

Cheers
