IMPLIED VOLATILITY BASED PRICING AND RISK TOOL AND CONDITIONAL SUB-ORDER BOOKS

摘要

The Book Order Management (BOM) system provides a fully automated and efficient electronic trading environment for derivatives trading. The BOM system allows traders to electronically, in real time, both make two sided markets in any option or combination of options, and issue quotations for immediate use, so that the trader providing the quotation has the opportunity to re-evaluate and change markets if conditions change. The BOM system provides a way to efficiently determine whether the conditions placed on a contingent order are met and guaranteed, using a lock (freeze) and reserve procedure.

1. A method of executing a trade in an automated options exchange, the method comprising the steps of:
receiving at a processor a plurality of order books from at least one trader, the order books collectively containing a plurality of bids and offers, the order books being received from the at least one trader via a network operably coupled to the processor; storing the plurality of order books in a memory associated with the processor; receiving at the processor price and risk matrix data and trading criteria data from a second trader; storing the price and risk matrix data and trading criteria data in the memory associated with the processor; receiving at the processor a request to execute an order from the second trader, the request being received from the second trader via a user interface coupled to the network, the order within the request comprising one or more order parameters; validating the order contained in the request to execute an order to confirm that the order is valid; matching the order with one or more of the order books by searching the order books contained in the memory for one of a corresponding bid and a corresponding offer meeting a parameter of the order; determining whether the one of a corresponding bid and a corresponding offer has been previously locked by the processor as a result of execution or partial execution of another trade; waiting for the one of a corresponding bid and a corresponding offer to become unlocked if the one of a corresponding bid and a corresponding offer has been previously locked by the processor; locking an order book contained in memory that contains one of a corresponding bid and a corresponding offer matching the order; placing a reserve on order books having conditional orders that have been determined match the order; validating the price and risk matrix data and the trading criteria data associated with the second trader to confirm that fulfilling the order will not violate either the price and risk matrix data or the trading criteria data of the second trader; executing the trade if the validating step was successful; and updating the associated order books having at least one of a bid and an offer involved in the trade.
