,,I have three margin accounts,,,,,the only calls I have gotten are ones for account maintenance where I have to ensure that the account always carries a minimum of 5% cash at all times. Not sure why margin calls would be issued last week when RVX was in an up mode,,,very possible if the play was heading backwards where one has to keep adding to his or her deficit.,,,I do not generally buy on margin,,,although I have at times in small chunks,,its hard enuff to guess which way any stock goes without the added stress of using margin!,,jmo
