To keep a seat as a MM it will cost you around $ 55 000 a month (minimum is $4 000 000 a year), so let me tell you any and every deal out there is needed and welcomed ! with today's technologies, it is very simple and efficient for them to act on all orders ! the old days of somebody sitting at a desk doing everything by hand is long gone... so to yes today's trading for THIS and all other stock is very important to them and treated as such.
