I trade with IB and I write options. Occassionally I get a margin violation which I try to correct by buying the positions back. Sometimes the positions are grossly overpriced, i.e. the exchange values the option at 2 points but the offer is 50 points, and my offer is not executed. When IB's automated trade quicks in and has purchased the option at 50 points, I have successfully called IB and got the trade busted. On other occassions when the offer has been say 5 or even 10 times the exchange value for the option, and the automated trade kicks in, I have taken the hit on the chin. What I'm wondering is at what level can I realistically get a trade busted when this occurs? Are there rules stating that when a trade is executed at say 200%, 300% etc of the exchange value, it can be busted? When I have called IB to get a trade busted due to grossly overpriced offers, they already new about the trade and handled it proffessionally. Please don't reply by saying "option writing is bad, mkay". Thanks for your responses in advance.
