All I know about chart pasterns and basic stock market "wisdom", is that once you know the rules, they change them.  Bull flags used to be defined as a big move up and then a tight sideways or slightly downward movement for a short period of time.  But, in 2009 I started seeing a really good pattern for a bull flag was one with a slightly upward bias.  WOW, that was the best.  Under the older "wisdom" it was best to watch and buy on a breakout of the flag or put in a stop buy.  Or take your chances and buy and hope. But with a slightly climbing bull flag, you could buy and get paid while you wait.

So ADY, lol, I like the upward bias the last 3-4 weeks.  If it was a form of a triangle, it has broke out?  But, I am one who likes volume building up  before a big move up.  I don't see it here yet.  But, now that is changing as well.  Since the middle class and up have taken it on the chin the past 5 or so years, volume does not seem as necessary since overall volume is falling overall.

Warning, I am an expert in only one area, and that is  MY OPINION, nothing else.
