Here is a list of current Flags or displaying flag type characteristics as of 12/3/2022. I'm sure there are more, however this list was populated from my trading universe - Add AMKR to that list
i would disagree on a lot of the symbols you have listed there as to there being flags due to lack of momentum and no previous run up. But to each his own. Please note that im not trying to be argumentative, only constructive. Volume plays a key role in the pattern
