## Title
Processing binary options in future exchange clearing

## Abstract

Systems and methods are disclosed for processing binary options (also referred to as digital options) in existing clearing systems, such as futures clearing systems. The binary option is treated, or processed, similar to standard options on a non-tradeable cash-settled underlying futures contract. A hypothetical instrument, referred to as a book instrument is created to facilitate clearing of the binary option. The book instrument has an expiration date after the expiration of the binary option, such as the day after the expiration of the binary option. For each binary option that expires in the money, a transaction is created for the book instrument future. The underlying book future has an assigned price that is a fixed amount less that the final price for the underlying statistical or actual value of the binary option at expiration. Transactions are loaded in the clearing system and processed and all positions are liquidated. Options exercise and assignment processing is performed in the clearing system as well as an associated clearing firm bookkeeping system.

## Background
The present application claims the benefit of U.S. provisional patent application No. 60/803,472, filed May 30, 2006 and entitled “Processing Binary Options in Future Exchange Clearing,” the entire disclosure of which is hereby incorporated by reference.


FIELD OF THE INVENTION
The present invention relates to clearing positions for expired options, and more particularly, processing binary options as a non-tradeable cash-settled futures contract.
DESCRIPTION OF THE RELATED ART
Clearing processes are performed for derivative products, such as options or vanilla options, after an expiration date for the derivative. Derivative products include options on futures contracts, futures contacts that are functions of other futures contracts, or other financial instruments that have their price related to or derived from an underlying product. A clearing house may process or clear the derivative in a similar manner as for other derivatives, such as in existing futures bookkeeping systems. The clearing house may break a derivative trade into a series of trades that appear to a member firms' bookkeeping systems as if they are standard monthly options on monthly cash-settled non-tradeable futures. That is, a series of trades are not futures and futures-options, but may provide the appearance as such so that they may be easily processed in existing bookkeeping systems.
Binary options, including binary range options, (also referred to as digital options) are cash-settled options that pay a fixed amount if the option ends up in-the-money. The payout amount does not depend on the amount by which the option ends up in-the-money. For a binary call, the option pays if the final value of the statistic or actual value is greater than or equal to a strike price for the option. For a binary put, the option pays if the final value is less than the strike price for the option. A binary range option may have multiple strike prices, such as a lower and an upper strike price. The holder of the binary range option receives (and the seller pays) the fixed payoff amount if the final value of the statistic ends up greater than or equal to the lower strike, and less than the upper strike.
Because of the digital or binary nature of the option, existing clearing systems may not be readily configured to process or clear a binary or binary range option. To directly process these instruments, systems handle (a) the different product characteristics—for example, the binary range options, with fixed payouts and two strike prices, (b) trade quantities which may be expressed as nominal amounts and very large, and (c) strike prices which may be negative. Therefore, the clearing house will break up each trade in an actual auction instrument into a series of trades that appear to be ordinary options trades, in standard monthly options on cash-settled non-tradeable futures, and should flow through firm bookkeeping systems with practically no modifications. Such processing is time-consuming and requires cumbersome decomposition of the option.
Therefore, there exists a need in the art for systems and methods for conveniently clearing and processing binary options.
SUMMARY OF THE INVENTION
Systems and methods are described for processing binary options (also referred to as digital options) in existing clearing systems, such as futures clearing systems. The binary option is treated, or processed, similar to standard options on a non-tradeable cash-settled underlying futures contract. A hypothetical instrument, referred to as a book instrument is created to facilitate clearing of the binary option. The book instrument has an expiration date after the expiration of the binary option, such as the day after the expiration of the binary option. For each binary option that expires in the money, a transaction is created for the book instrument future. The underlying book future has an assigned price that is one less that the final price for the underlying statistical or actual value of the binary option at expiration. Transactions are loaded in the clearing system and processed and all positions are liquidated. Options exercise and assignment processing is performed in the clearing system as well as an associated clearing firm bookkeeping system.

Exemplary Embodiments
FIG. 2 shows a flowchart for an exemplary method for clearing options. In the method, a binary option may be processed without cumbersome decomposition into vanilla options.
In an embodiment, a clearing system is used to process an expired binary option. The binary option is processed as a standard option on a non-tradeable cash-settled underlying future, also referred to as a “book instrument.” (i.e. it is only to facilitate processing in clearing firm bookkeeping systems.).
The book instrument is defined to have an expiration date after the expiration of the corresponding binary option. For example, the book instrument may have an expiration date the day after the expiration of the corresponding binary option. In other embodiments, the book instrument and binary option may expire the same day with the binary option expiring before the book instrument
The non-tradeable underlying future's maturity date may also be set to expire the business date after the real option expiration date.
On or before the real expiration date, trading ceases for the binary option. Option expiration processing for the binary option is not run on the normal expiration date for the binary option, since the date is defined in the clearing system according to the book instrument as the next business day.
On the expiration of the book instrument, such as the day after or intra day after the expiration of the binary option, exactly liquidating transfer transactions are created, loaded into the clearing system, and transmitted to clearing firms for loading into their bookkeeping systems, for each expired binary option position. For example, if a position in an expiring option was 35 long by 17 short, then a sell trade for 35, and a buy trade for 17 are created. These transfer transactions are defined as liquidating, either trade by trade (if that is how the clearing system operates for these products), or implicitly by specifying an ending position (“position change specification”, or PCS) of zero by zero.
For each binary option position which has expired in-the-money, transactions are created for the underlying “book” instrument future, at a price with a value a fixed amount, such as one, less than the final price for the underlying statistic of the binary option:

    
    
        i) For long call and short put positions, the book-instrument futures transaction is created as a buy transaction; and
        ii) For short call and long put positions, the book-instrument futures transaction is created as a sell transaction.
    
    


The liquidating transfer transactions for all the expired binary option positions, and the “book-instrument” futures transactions for those which finished in-the-money, are loaded into the clearing system. This in turn causes messages to be transmitted to clearing firms to allow the transactions to be loaded into clearing firm bookkeeping systems.
As clearing processing continue, no other transactions in these options are allowed to clear on that day; no special option instructions (exercise notices or option abandonments) are accepted, nor any position adjustments or other transaction which could affect the ending option position. The net effect, together with the liquidating transfer transactions that have been posted to the expired option positions, is that all such positions are liquidated.
Option exercise and assignment processing is run normally in both the clearing system and in clearing firm bookkeeping systems for the binary option positions, as if they were vanilla options, since the expiration date in the clearing system has been set to a later date or time, such as the next business day. However, since all of these option positions have been liquidated, there are no positions to exercise or assign, even for the ones which finished in-the-money. Hence the fact that exercise and assignment processing is run as if for vanilla options, creating transactions at the strike price, has no effect.
At the first clearing settlement cycle of that day, the special futures transactions for the in-the-money options, created at a fixed price, such as one, less than the final value of the option's underlying statistic, are marked-to-market to that final value. This process, which occurs in both the clearing system and in clearing firm bookkeeping systems, causes the binary payout cash flows to occur.
Money calculations for the book instruments—When calculating premium for trades in futures options in a bookkeeping system, the trade price is multiplied by the contract value factor (the multiplier that converts the quoted price to its monetary value) and the trade quantity. In other words, for futures options, calculate the premium for a quantity of one, then round, then multiply by the trade quantity.
The present invention has been described herein with reference to specific exemplary embodiments thereof. It will be apparent to those skilled in the art that a person understanding this invention may conceive of changes or other embodiments or variations, which utilize the principles of this invention without departing from the broader spirit and scope of the invention as set forth in the appended claims.
