YES! I believe it should be on Robinhood. They took the risk of giving an unemployed 20 year old "almost a million dollars" in leverage, that could not pay the negative $730,000.
damn the kid just decide to kill himself while not really a real negative balance? not familiar with robinhood but if they can be sued for this tragic death, it would help the future platforms to also follow a standard.
the kid started trading at this early years of his life, he could be learning a lot and will likely be a pro before 25. but that wouldn't happen now because of the gui that robinhood provided.
This is how I see things here, there is some liability on the part of Robinhood and I'm sure they know this sort of short comings or some error that this platform has provided. I for now things that this is how they designed their system in the first place.
This kid has really a bright future, there's a lot of "If's and "could have" if he grow and become a veteran trader, sadly it was cut short and it's really a tragedy.
