A method for determining a closing price of a security traded in an electronic market includes receiving a trade price of an executed trade of the security wherein the executed trade is executed during a trading session of the electronic market, comparing the received trade price to a market parameter of the security to determine the closing price of the security, and reporting the determined closing price of the security to a user.

Closing price determination for an automated market system

A method for trading a security in an electronic market includes entering an order at a client station for executing against any market participant that can at least in part satisfy the order, determining a threshold for executing the entered order based on an inside price of the security in the electronic market, matching a portion of the entered order at a server system against interest in the market that does not exceed the determined threshold, and returning any unmatched portion of the entered order that can not be matched by the interest in the market without exceeding the determined threshold.
