Quote from bone:
I would like to politely disagree - it is all about ECN resources and getting paid for them. How does an exchange and a clearing firm manage ECN resources and make any revenue when you have retail punters flooding the system with messages and actually executing trades very, very little ?
Exchanges and clearing firms get paid on EXECUTION fees. You simply cannot let someone flood the ECN with 1,000 messages for 10 fills. Makes no sense. And it is bad for the other traders who choose to participate more actively in the markets and who will need those resources to execute live trades under times of market stress.
Think about it. There is a very, very good reason for a message-to-fill policy. And all electronic futures exchanges that I am aware of have those policies.
