What do you care? Are you looking to start a clearing firm? ...and i would venture to guess they pay less then .002...in fact, due to volume I would go so far as to say .75-.85 cents per 1000 but m just guessing.
It has to be lower. There are offices of other firms that get cleared for less than .002 and they probably don't even approach 1/10th of the volume as Bright does as a firm. Bright has other expenses, so it's not like it's all going into their pocket.
I know firms that charge $1 per 1000 shares and do less volume then bright, so I would assume that he is paying less.
