### Comment:
&gt; Robinhood financials and/or RHS can increase its respective 'house' margin maintenance requirement at any time and is not required to provide you advance written notice 
  
 Like wtf... Is this even legal?

### REPLY:
Yes. Every broker does that. Regulations define the minimum margin requirements (ie, max leverage) but the broker has the possibility to increase margins to manage their risk.
