"TRADEKING adds $0.01 per share on the entire order for stocks priced $2.00 or less." could be applied literally or could be like OptionsXpress. OptionsXpress states Qualified active stock trader customers must maintain 9 or more stock trades per quarter to maintain the active stock trader rate of $9.95 per trade (up to 1,000 shares and $.01 per share for 1,001 shares and above). But if you look at the following two orders, you will note OptionsXpress does not compute it that way. If they did commissions on both trades should be $49.95 (according to my calculations) (Note: I have never paid anything other their estimated commission)
