ontarget, the MM's do not have to take all orders.
The MM obligations are as follows:-
1- To stand behind their quote on SETS in the agreed EMS (exchange market size) - 50,000 shares for Hemo
2- To place a live quote on the RSP (retail service provider)
3- Negotiated trading - broker (has buy order for 750,000 shares) rings MM and asks for a two way price and size. MM responds 8.9 - 9.05 in 200,000 shares. Broker says I will lift you in the 200,000 and can I leave you to work 550,000 further shares.
MM can say yes or no to the further order with no obligation to trade the balance.
That is exactly how it works.
