Quote from jones247:
I'm sorry guys, but I just don't buy it... since when did any broker, particularly IB, start looking to protect the customer from losing money, or even blowing out their account???.... If that's the case, then I guess we can all assume that our respective brokers will always be there to keep us out of risky trades that can wipe us out.. "Yeah Right"... again, I'm not buying the "we are saving you from yourselves" argument as a justification for the disallowance. Otherwise, there are several other instances where the broker should have stepped in and saved the trader from devastating losses!!!
There will zero natural demand in the ES options in the back months. You could cover the wings and leave the naked strangle. I agree that the individuals will show a mkt, but they can't enforce which you choose to cover first unless it would put you on call. A very real possibility that you may not have a mkt in the short combo, at all.
I understand it's the principle with you, but why not simply trade the SPX or SPY? There you have a native combo order (you don't in the ES) and it won't be subject to a mark against a futures contract with zero-volume.
