looking at a 10 year chart I can see a 5-3-5 retracement off the march low and works out real nice with a 50% retracement of the OCT 2007 high and pretty close to a A=C ....
it's been an interesting price move in 7 months and profitable .... that type of a move usually is associated with a down move rather that a bull move up in a bull market (now what kind of a rally is that called ???)
u like Lucas Numbers ???
oct 07 to apr 09 is 18 months and apr to oct 09 is 7
