Method and system for maintaining an order on a selected market center with maximum price exemption parameter

摘要

A posting market center and process are disclosed for maintaining a market center-restricted order on a selected market center. In a market which allows price exemptions, the market center and process disclosed hide a received market center-restricted order which technically crosses or locks the away market, but would be marketable if an acceptable contra-side order was then available in the posting market center's internal order book. The posting market center then maintains this hidden order until it is fully executed, is canceled or can be displayed on the public order book.
