If push came to shove I'd vote for the "No Brokers should not reflect true market conditions" faction.
Two reasons for that:
A: Habits die hard, and inventive price quotes are bang down the alley of the OTC bucket shop brigade.
Respect due where it's due, and they've got that down pat to an art.
B: Where would all the fun end up at if they'd reform their ways and actually show prices that reflect what happens in the real market ???
No no, upon careful and considered reflection let's let things stay as they are.
