What do you know about his clients and what could you possibly know?
As much as as you can know about them when you sit next to them as well as networking with them during an Armstrong's conference.
I suggest to get out from your troll cave and attend his next conference. You will meet me there (yes, some retail traders like me attend his conference), which will provide you a wonderful opportunity to apologize in person for your personal insults, and most importantly you will meet some of his serious clients there.
In the meantime until you save up your high school lunch money for the conference you need to fuck off from here son. Your personal insults and trolling is not cool. You feel it is important to reiterate your wisdom about Armstrong and to tell us how stupid we are here that we find more or less value in Armstrong's work, which is a sick fuck troll attitude. Open the "I am so smart and have proof that anybody who find value in Armstrong's work is stupid" thread and discuss there why Armstrong is a useless analyst. This is the thread where we are more or less positive about Armstrong's work. You made it clear that in your opinion there is no value in Armstrong's work. Therefore, your work is done here - reiterating your opinion is patronizing in a thread which purpose is to take the positives from Armstrong's work.
