Contact IB and ask why you got rejected. Simple as that. If you have been honest with them and provided requested information then they are honest with you. My experience.
Have you tried the most obvious place, which is NinjaBrokerage? They will also be your best bet for support if you can't get stuff to work with the NT software.
So I click the link located below with the red arrow on NT's site... And I get forwarded to this application screen. Note the other red arrow... I love arrows. From here you are on your own.
Then you are done. You can no longer trade the ISO symbol on NT 7 or 8 forEVER, and you will never make any money ever again. I mean, SERIOUSLY? ISO, whatever the fuck that is, is what keeps you from making money? WTF is wrong with you?
i requested a reason and they only respond with "management decision" and declare they dont have to give me a reason
