### Comment:
Well, they may have been negligent to their investors or owners but the only person negligent to OP is himself.

### REPLY:
No, brokerages have a duty to make sure that their investors aren't uninformed and do tremendously stupid things like this.  
  
 Yes, OP needs to have some idea of what they're doing before they take quarter million dollar positions, but the brokerage needs to act as a gatekeeper as well. The fact that they immediately disabled this type of position for the rest of their clients strongly indicates that they screwed up their risk management.
