| 20090006238 | MATCH SERVER FOR A FINANCIAL EXCHANGE HAVING FAULT TOLERANT OPERATION - Fault tolerant operation is disclosed for a primary match server of a financial exchange using an active copy-cat instance, a.k.a. backup match server, that mirrors operations in the primary match server, but only after those operations have successfully completed in the primary match server. Fault tolerant logic monitors inputs and outputs of the primary match server and gates those inputs to the backup match server once a given input has been processed. The outputs of the backup match server are then compared with the outputs of the primary match server to ensure correct operation. The disclosed embodiments further relate to fault tolerant failover mechanism allowing the backup match server to take over for the primary match server in a fault situation wherein the primary and backup match servers are loosely coupled, i.e. they need not be aware that they are operating in a fault tolerant environment. As such, the primary match server need not be specifically designed or programmed to interact with the fault tolerant mechanisms. Instead, the primary match server need only be designed to adhere to specific basic operating guidelines and shut itself down when it cannot do so. By externally controlling the ability of the primary match server to successfully adhere to its operating guidelines, the fault tolerant mechanisms of the disclosed embodiments can recognize error conditions and easily failover from the primary match server to the backup match server. | 01-01-2009 |
| 20090055303 | OUT OF BAND CREDIT CONTROL - Systems and methods are provided that can provide credit control monitoring across any number of trading engines without adding any performance or scalability limitations. | 02-26-2009 |
| 20090059941 | DYNAMIC DATA FILTERING - Networks, systems and methods for dynamically filtering data are disclosed. Streams of data may be buffered or stored in a queue when inbound rates exceed distribution or publication limitations. Inclusive messages in the queue may be removed, replaced or aggregated, reducing the number of messages to be published when distribution limitations are no longer exceeded. | 03-05-2009 |
| 20090063360 | DYNAMIC MARKET DATA FILTERING - Networks, systems and methods for dynamically filtering market data are disclosed. Streams of market data may be buffered or stored in a queue when inbound rates exceed distribution or publication limitations. Inclusive messages in the queue may be removed, replaced or aggregated, reducing the number of messages to be published when distribution limitations are no longer exceeded. | 03-05-2009 |
| 20090089200 | PRE-EXECUTION CREDIT CONTROL - Systems and methods are provided to provide pre-execution risk or credit control for electronic financial derivative product trading. A portfolio risk management analysis method, such as the Standard Portfolio Analysis of Risk method, is used to determine how a new order will impact the overall credit or risk of a trading entity. The pre-execution risk control is performed on an order by order basis prior to order execution and may include an analysis of assets and orders for other financial products at the same or different exchanges. The risk level for a trading entity may be set by that trading entity, its clearing organization or the exchange. | 04-02-2009 |
| 20090106328 | FAULT TOLERANCE AND FAILOVER USING ACTIVE COPY-CAT - Fault tolerant operation is disclosed for a primary instance, such as a process, thread, application, processor, etc., using an active copy-cat instance, a.k.a. backup instance, that mirrors operations in the primary instance, but only after those operations have successfully completed in the primary instance. Fault tolerant logic monitors inputs and outputs of the primary instance and gates those inputs to the backup instance once a given input has been processed. The outputs of the backup instance are then compared with the outputs of the primary instance to ensure correct operation. The disclosed embodiments further relate to fault tolerant failover mechanism allowing the backup instance to take over for the primary instance in a fault situation wherein the primary and backup instances are loosely coupled, i.e. they need not be aware that they are operating in a fault tolerant environment. As such, the primary instance need not be specifically designed or programmed to interact with the fault tolerant mechanisms. Instead, the primary instance need only be designed to adhere to specific basic operating guidelines and shut itself down when it cannot do so. By externally controlling the ability of the primary instance to successfully adhere to its operating guidelines, the fault tolerant mechanisms of the disclosed embodiments can recognize error conditions and easily failover from the primary instance to the backup instance. | 04-23-2009 |

| 20100205113 | MULTIPLE QUOTE RISK MANAGEMENT - The disclosed systems and methods relate to allowing trading of over the counter (“OTC”) foreign exchange (“FX”) contracts on a centralized matching and clearing mechanism, such as that of the Chicago Mercantile Exchange's (“CME”'s) futures exchange system (the “Exchange”). The disclosed systems and methods allow for anonymous transactions, centralized clearing, efficient settlement and the provision of risk management/credit screening mechanisms to lower risk, reduce transaction costs and improve the liquidity in the FX market place. In particular, the disclosed embodiments increase speed of execution facilitating growing demand for algorithmic trading, increased price transparency, lower cost of trading, customer to customer trading, and automated asset allocations, recurring trades as well as clearing and settlement efficiencies. | 08-12-2010 |
| 20100223201 | Out of Band Credit Control - Systems and method for mediating risks associated with orders in an electronic trading system are provided. A front end component includes a plurality of trading engines that receive orders from traders. A back-end component includes a match system. The system includes a credit control module, which may be located at the back-end (e.g., clearinghouse), front end, a combination thereof, or other location that communicates with the plurality of trading engines. The credit control may monitor aggregate risk parameters for the trading engines and requests credits from trading engines. | 09-02-2010 |
