For swing trading we generally look at shorter cycles like the 13-17 TD cycle and get too fancy with our charts and analysis. Maybe we should KISS (Keep It Simple Stupid) like this:
update 12/23 - As suggested the averages set new highs here in the first part of the week. May have some upside left before Christmas??
update 12/24 - today the DJIA was up most of the session, but closed only slightly higher and SPX was slightly negative. What one would expect if a short term top was being made....
