Stefan_777,
You are once again not accurately describing my statements.
I don't think, and I never said, that an account complying with margin rules should be liquidated. You misunderstood me on this point. I suggested that the OP's account might have violated margin rules in ways he did not understand, and that these violations might have justified or necessitated at least partial liquidation of his account.
You also misunderstood my discussion of assignment risks. I did not raise them as an excuse for liquidating an account in compliance with margin rules. I discussed assignment risks in order to help explain why those margin rules were adopted by the federal government, and why additional margin rules were adopted by IB.
Let's assume, hypothetically, that an IB customer has a cash account, and that he initially met the margin requirements for entering his put spreads in a cash account. It is possible that subsequent events involving the account's other positions, such as commodities futures, securities futures, FX, etc., might reduce the account's cash sufficiently so that the account no longer has enough cash to support the put spreads. This would lead to a partial or total auto-liquidation within minutes.
Note that the changes in the put option prices would NOT reduce the account's cash balance, and so would NOT trigger the initial liquidation. The trigger would come from losses on positions other than the put spreads, even though this might result in partial or total liquidation of the put spreads.
You are once again not accurately describing my statements.

jim rockford,
Please provide references backing up why a broker can liquidate a spread that is in good standing within initial and maintenance margin, based on these special assignment margin risks (extreme dangers) you're talking about.

IB and other brokers require the cash account holder to hold the full amount of cash to pay for a potential assignment of the short puts. This is what they mean by paying the put strike price. Why in the case of a cash account would someone ever have to be liquidated if they have enough cash to cover the worst possible event, which is satisfactory to IB, american style physically settled or not?
In a cash account, they won't let you short a "naked" put unless you have enough cash to hold it till expiration and be able to pay for either the physical or cash delivery in full once assigned.
