^^You are very naive. Traders at CBOE/NYSE/ect...have an edge from their allies/companies/financial back-up/insiders informations.....these are what an average daytrader at home or working in a small prop firm doesn't have. It's why average Wall ST workers' salary is $500,000 & top university graduates will 'die' for Wall ST positions. There are a big difference between a GS trader vs home-daytrader. It's like the sun and the moon. Head GS trader bonus is 10 millions per year. Andrew oil trader at C was making $100M a year. How can you compare a pro & small shirmp?
