Signing a waiver or disclaimer is just legal fluff and worthless.  This is a finra regulated company in the usa. if they do wrong, screw you out of $ etc no waiver will indemnify them of all wrong doings. It does not give them the right to do what they claim.  It is only a deterrent companies use to head off lawsuits.  in other words convince you not even to file because " it wont go anywhere"   Bull hockey. Only way to hold exchanges accountable is sue them when they screw you. otherwise everyone will eventually be screwed.
