I currently use Preferred Trade, but after several days of email exchanges I've found that they aren't planning to implement the newer, more favorable margin rules on hedged positions (e.g., long equity/long put, etc.). Looks like MrStock has already implemented these rules. Anyone have any experience with these guys? Also, anyone know of other brokers who recognize the newer margin rules? I've had good luck with Preferred, but really want to be able to take advantage of the more favorable requirements for these type positions. Thanks.
