Yes, their are differences, but it is the same model that was pretty close to be right in May 2000, late December 2000, April 2001, Late September 2001, failed (only partially) in July 2002, but got back in again in October 2002, and yes, we did not get these extremes in March 2003, so what am I going to do? Throw the towel or stick to these indicators and their various weights? Got to stick with them, and take the losses when stops are forced on me.
