if you think it is such great business buy publicly traded brokerage firms. I use to hear the same about the oil business when oil started to trade over $50. take a look at LT charts of oil co's and bds. it is remarkable that executing firms make a profit charging .003 to .005. these bds are not particular money machines. you didn't include taxes in your calculation.
Because I can't take the swings by adding another zero. I run of this of blowing up. I'm getting out of the game. At this point, it is too risky for me. I just CANNOT go bust.
Jesus. Shop around ASAP. I'm with NY0B on this one. Negotiate with your firm or get a 0.20/1000 shares quote and get your dues.
Ever considered finding trades for more than a penny a share ? They are out there. I never met a rich scalper.
