Does anyone know about commisions at Bright Trading? I know they have some flexiblity for different styles, but with 100% payout, they have to make money somewhere, right? I currently pay $2.75 per thousand shares at much less payout. But I trade volume on the heavy side, around 400,000 shares per day and average about $3,000-5,000 in gross PL. Wondering if I could go to Bright and still be profitable. Thanks for any input.
