Caliber,
I assume you have been in the business for a while. Don't you feel many new traders just don't know how low the commission rates can go?
I feel if a trader is paying $8 per 1000 for DAT that's way too much.
Heck the savings of $3 per 1000 shares adds up.
$3 x 20 (10 buys and 10 sells per day) = $60 per day
That's about a $15,000 per year raise. Not to mention, it could be the extra cushions that helps a newbie succeed instead of the BD getting all the $. Not many firms are willing to help a newbie out like this (such a shame)
Now you have a long term revenue stream (Cheap commissions + good trader = lifer).
