With a 'per share' broker like IB, trading $100K of a $5 stock = 20,000 shares => $102,5 fees (IB). Trading this same $ amount with a $100 stock = 1,000 shares => $7.5 fees (IB)! On the other end, 'per ticker' brokers like Ameritrade don't have NYSE native Market On Open and Market On Close orders which I need to use. Do you know some online broker with native NYSE MOO and MOC orders charging fees per ticker or per $ amount ? Thanks for your coments.
