Abstract
A posting market center and process are disclosed for maintaining a market center-restricted order on a selected market center. The market center and process disclosed aggressively maintain a market center-restricted order that would normally lock or cross an away market by initially pricing the order a tick increment away from the contra side market best bid or offer and then dynamically re-pricing the order in increasing aggressiveness as the away market best bid or offer moves its quotes further away from the order's currently displayed price. The disclosed market center-restricted order stands its ground to an updated away market best bid or offer that moves to its price or through it.
