At the end of 2008 I traded some illiquid future contracts between my friend's account and my traditional IRA account. In doing so I transferred $28000 to my IRA account. I didn't know that it is illegal. My account was frozen on the next day. An IB compliance officer called me a few days later and asked why I placed those cross trades. I said I was doing some testing. Now I know that cross trades are illegal. What will happen to me? Has IB reported this to FBI? And what should I do? Any suggestions will be greatly appreciated.
