Algorithmic model to allow for order completion at settlement or at close using exchange mandated rules for settlement determination

A system for managing one or more Market-On-Close (MOC) orders, comprising:

• a trading system comprising one or more computing devices, each of which include one or more processors, in operable communication over a network, configured to:
• store market data and one or more settlement rules associated with one or more exchanges, wherein the one or more settlement rules are associated with one or more financial instruments traded on the one or more exchanges;
• display, via a graphical user interface coupled with the trading system, an order entry dialog window illustrating one or more definable order parameters for the one or more MOC orders, wherein the one or more definable order parameters comprises a limit price parameter;
• receive the one or more definable order parameters for the generating one or more MOC orders, wherein the one or more definable order parameters identify at least the one or more exchanges or a financial instrument;
• and
• send the one or more MOC orders to the trading system, and wherein the trading system is in operable communication with the one or more exchanges.

A non-transitory computer-readable medium storing instructions that, when executed by a processor, causes a computer system to manage one or more Market-On-Close (MOC) orders by performing the steps of:

• storing market data and one or more settlement rules associated with one or more exchanges, wherein the one or more settlement rules are associated with one or more financial instruments traded on the one or more exchanges;
• displaying, via a graphical user interface coupled with the trading system, an order entry dialog window illustrating one or more definable order parameters for the one or more MOC orders, wherein the one or more definable order parameters comprises a limit price parameter;
• receiving the one or more order parameters for generating the one or more MOC orders, wherein the one or more definable order parameters identify at least the one or more exchanges or a financial instrument;
• and
• sending the one or more MOC orders to the trading system, and wherein the trading system is in operable communication with the one or more exchanges.
