Quote from jayre:
It seems that you say that a debit spread would not trigger liquidation. But I had an instance that the âonlyâ position in my account was a call âdebitâ spread and I got liquidated. Would you care to explain IBâs official policy regarding debit spreads?
To be fair to Def I don't think he was saying that a spread won't trigger a margin call, just that the spread wasn't the main cause in the case referred to.
But the problem of the auto liquidation software making illogical trade choices during liquidation remains under-addressed by IB here.
