Shouldn't this page incorporate information about: a) How these trend lines correlate to Linear regression#The_trend_line? (eg. presumably computer generated ones for shares also use linear regression? b) How effective (or not) this method is generally recognised to be? (ie. there must be literature that discusses the validity of trend lines over time in various markets) Natebailey 11:12, 24 March 2007 (UTC)[reply]
