i have a question for those who own or lease a seat in an exchange. according to robert green http://www.greencompany.com/Educati...ntTraders.shtml people who are members of an exchange get charged "self-employment tax". as opposed to other types of traders that are exempt from this. is this in fact true? that would be a big issue as it would take away the benefit of lower commission rates altogether. any info/feedback would be appreciated.
