This is the link to the archives of Bruce Frasers Wyckoff blog on Stockcharts
Archives back to the first one published in April 2015, thought I'd share as I've found these to be incredibly informative, amazing how often I've found, when searching out information, many others refer back to these as well. There is a link in the first blog to a YouTube video with Bruce and Roman Bogomazov going over some commonly asked questions that was very good, I find Roman to be a very clear with his information, @Jako64 may have shared this earlier in this thread as I'm sure I've seen it or something very similar here before.

After recently listening to Roman refer to the character of the Phases, id have to say AHZ made a much more characteristic Phase D move today, Increasing spread and volume, after first attempting to shakeout holders in Phase C, it appears the next step after a brief rise most likely due to the supply vacuum of the shakeout, was to bore holders while still just making higher lows by a pip, or what appears to be a very drawn out ST of the shakeout. Todays move up was quite sudden and no doubt caught a few out closing on its high.  
The high of the TR set by the AR is .38, however I believe price needs to clear .39.5 (high of the upthrust) to create a SOS before any possible Back Up to confirm this Phase D, watching for any negative volume showing hidden supply that doesn't appear to be there at the moment as there is still the possibility that this could be an UTAD, looking to draw out more demand to sell into, which would more than likely completely reverse this rise over the next few days. Needless to say I'm long here but interested if there are any alternate views as up until today, volumes and spread have not been "characteristic" of Phase D.
