Just got F*kd by IB's auto liquidation!
I had a bunch of multi leg SPY spreads, with a small delta.
I got early assigned this morning on 65 puts 2 days to expiry and found myself with 1.x Million worth of spy on a 70k account, so margin deficient, fair enough. Since the assigned options were offset by other options in the spread, my net profit didn~'t change, and delta increased slightly, expecting ~+- 500$ per SPY point.
Problem is when I tried to liquidate this morning by closing the offsetting long put and sell the stock, IB's TWS stops me saying I am trying to sell a combo and I don't have permissions. whaat?? I'm already trading options entered via spread orders, wtf??. I go to my account management, I don't see anything related to combos as a separate trading permission. In the meantime, IB starts auto-liquidating -- and besides the stock, partially liquidates my other, multi-leg spreads *at market* on all legs hitting me with massive bid-ask leakage --and doesn't sell my original offsetting puts at all.
Result: 28k realized loss instead of +-500$ on a 69k net liquidation value prior to liquidation.
If they had sold 65 of the offsetting puts at market I would have a small bid-ask loss, prob not more than -1k.
How is that not unfair? Do I have any realistic recourse here?
