They are considered a bearish consolidation pattern, however according to Bulkowski's reference work they have a 45% failure rate(can break upwards). If one waits till the pattern is confirmed(breaks down through support) then the pattern then has a 4% failure rate.
KZL has broken support (not on big vol) and since climbed straight back above, so perhaps a bear trap and KZL(chart wise) lives to fight again.
I see what you are saying re Macd and as all the troughs are near enough at the same level and Macd is climbing, one could take this as bullish divergence and expect it to head further North...will it?
If one looks at the over all trading action for the past 12 months it is locked in a sideways dribble(with tradable rallies). The weekly basing system I use giving no signals for now...not to say it wont have a rally, but still some work ahead of it yet to get any serious lift.
