I would like to suggest that the exchanges be modified such that when a sale
of a give item is made at a given price that the sales quantity gets divided
by all sellers offering the given product at the given price. Various ways
can be devised on how to divide up the quantity between the various sellers, I
won't address that here, but I think the resulting system is both more
representative of how actual markets work and will allow merchants to more
fairly offer their goods for sale.
