margin models change at brokers convenience its how they are able to steal yourmoney on options even when you pay them 10 times market width. for that reason i no longer trade options with brokers. if you do its v risky and im not sure really sure how you would deal with it its certainly not feasible risk revard v everage (they seem to charge many times the underling plus their vol markets and whatever else and often change if some idiot wises up to in the money options as if you are screwing them: imagine how much can u pay them to do nothing) its like any other shit. they can and will be dealt with its amusing tho when they say CJNJ are not nice or something. brokers would be buried under the jail they wouldnt last a day
