i chatted with an ex mm on stock xchange floor ... he now manages his small hedge fund. He told me it got really crowded on the floor during the bubble period. of course, now with decimalization it's hard to earn a living market making
Let's be realistic. Only the very best top gun traders can make >100% per year.
Even if you were in the top echelon, 100% on 20K is only 20K. You would make only slightly more than someone working at Mcdonald's.
I agree that you should get a real job and trade part time like others...
