With all due repect I think you're the one who doesn't understand. Banks absolutely have a choice whether to fill or not. Usually it's in their interests to fill. 10-100 milliseconds after a news release it's in their interests not to fill. They don't fill. As you say, they alter the bid/ask before they start filling. Of course the price can still move after the initial spike but you dont need "autoclicking" to get in after the initial spike.
