so I transferred all of my assets out of the Robinhood and into webull.... and I just received an email from webull telling me that my account has margin assets and my account is in trouble... it says all of my assets have been transferred from Robinhood but none of them have shown up on webull yet and webull is now telling me that my account has dropped below value... telling me that I need to close positions and I don't even know what the hell that means. I'm about to have a damn anxiety attack because I have had $1,500 worth of the AMC just vanish even though it's where's it's there and I don't know what any of this other crap means I am way too smooth brain, somebody please help me out here before I wig out
