A high (ITD #3) around Equinox - a Gann Natural Trading Day clustered with more astro-events (HERE & HERE) - would also be perfectly in line with the seasonal pattern:
2008-11-05 High + 1416 CD = Sep 22 (Sat) = 4 Lunar Year Cycle (LTD)
2011-10-04 Low + 354 CD = Sep 22 (Sat) = 1 Lunar Year Cycle inverted (MTD)
2012-05-29 High + 118 CD = Sep 24 (Mon) = 4 Lunation Cycle (ITD)
Though THE high projected for late August is not in yet, the 1972-2012 correlation = 40 year Cycle has increased to 89% !
