its is a sub llc for generic trading. they use to clear through andover. there are alot of great guys in madison, however their equipment is out of date and the network unstable. as far as generic goes they use redi, your commission rate can only go so low with a firm using redi/clearing through slk. the most important thing about generic is they are a philly firm not nasd or nyse. this means your licenses expire after two years with the firm.
