Quote from Spunky:
Here is what IB states on there web site.
"US resident customers may open cash or margin Individual Retirement Accounts (IRA). IRA margin accounts may never borrow, but are afforded all the other benefits of a margin account such as the ability to day trade, and the ability to trade multiple currencies and multiple currency products"
Yes that includes futures. I do it everyday
Then IB is violating US law. You may find out that your IRA becomes invalidated along the way. This is not something IB is allowed to circumvent.
