I traded several futures spreads in CL in my IRA this morning. I also tried entering outright futures limit orders in CL to either of my two accounts (IRA & roth-IRA) and had no trouble doing so (but I cancelled them before they filled).
I never contacted IB or did anything special, just noticed this morning that quotes for outright futures can be added to TWS again in my IRA account.
I logged out, then back in. I get futures quotes... no problem... but when I initiate a transaction, the account field is blank with no options. Sorry to trouble you... Are you sure you can enter an IRA account into the account transaction field for a futures trade?
