If you look at the 1974 crash and graph the daily DOW index and compare that graph to the current crash on a graph (go to google finance
http://finance.google.com/finance?q=INDEXDJX%3A.DJI )....they are following the exact same pattern (in a shorter time span for this one which I attribute to the speed of technology these days)
Anyway, back in 1974, the DOW lost 55.1% of its value from the high to the low. Based on our high, we should (big should of course) bottom out around 7,771 if the trend continues before we pull out of this dive.
I know this may be slightly different, but the coincidence of the pattern is a little interesting. Here is a picture Where I compare the two.
