Acknowledging themselves as legends and only labeling themselves, not from others, is a mistake that makes them arrogant.
Traders who are really professional and know how the market works, they don't do any flexing and don't think of themselves as trading gods,
they consider themselves to have no more knowledge and have a lot of mistakes so they can continue to be vigilant and correct themselves.
I have followed many arrogant traders and they trade and make a profit it is not that their analysis is wrong and they are doing anything wrong but the behavior is what makes other people buy you. Either you are not selling, having good behavior like listening to other before sharing your own high-class knowledge, without getting others' issues first is not good and arrogant.
They don't behave nice even and when they liquidated their accounts they even don't come to their senses but I don't want to talk about someone's behavior here just to point out that traders must have a open heart and willing to accept their mistakes so they could learn more and that's the right thing for any trader either streaming or have any community or not.
