Abstract: Methods, devices, and systems for communicating market data with market participants involve obfuscating at least a portion of a first financial message. Communicating the market data also involves augmenting a second financial message with a key configured to remove the obfuscation from the obfuscated portion of the first financial message. The market data is ultimately communicated by transmitting the first financial message to a particular participant, and transmitting the second message to a plurality of participants. The particular participant may then use the key from the second financial message to remove the obfuscation of the first financial message.

Abstract: A data transaction processing system receives electronic data transaction request messages from client computers over a data communication network and augments each message with hardware level data, and generates a monotonically increasing identification number for each electronic data transaction request message based on the hardware level data. The data transaction processing system transmits the identification number to the client computer utilizing transport layer protocols.

Abstract: The disclosed embodiments relate to communication of financial messages from an Exchange to market participants whereby messages, or at least a portion of the content thereof, indicative of changes in the market, due to one or more trades between two or more market participants, are structured so as to reduce redundant data therein and prioritize the transmission of that portion of the message which summarizes the event and result thereof. Further, these event reporting messages may further consolidate, or otherwise be combined with, the corresponding directed reporting messages communicated to the particular market participants participating in the reported trade while preserving the anonymity of those market participants to which messages are particularly directed.

Abstract: A data transaction processing system receives electronic data transaction request messages from client computers over a data communication network and groups a subset of the electronic data transaction request messages. The data transaction processing system may preprocess the group of electronic data transaction request messages based on the other messages in the same group before forwarding the electronic data transaction request messages to a transaction processor.

Abstract: A data transaction processing system receives electronic data transaction request messages from client computers over a data communication network and groups a subset of the electronic data transaction request messages at varying intervals. The intervals may be dynamically determined and may be based on the volume and rate of the incoming electronic data transaction request messages. The data transaction processing system may preprocess the group of electronic data transaction request messages before forwarding the electronic data transaction request messages to a transaction processor, which processes the subset of electronic data transaction request messages in a non-chronological order.

Abstract: A data transaction processing system including multiple transaction processors also includes an active transaction receiver that sequences all incoming messages from various sources to facilitate transactional determinism, as well as a results arbiter to efficiently decide which transaction processor result to choose as the correct output. The data transaction processing system minimizes overall latency by optimizing which transaction processors and results arbiters are responsive to specific client computer input requests or messages.

Abstract: A data transaction processing system including multiple transaction processors also includes a resource allocation system that characterizes the transaction processors based on input output electronic data transaction request message patterns associated with the transaction processors. The resource allocation system dynamically allocates computing resources, such as data path bandwidth, processor priority, CPU cores, memory, and processing threads to the various transaction processors and components therein based upon the transaction processor characterizations, improving the overall processing throughput, resource utilization, and efficiency of the multi-transaction processor system.

Abstract: A data transaction processing system includes a latency detection system that determines whether an observed latency associated with an incoming message exceeds a specified latency threshold for that message. In an embodiment, a message that exceeds, or will exceed, its specified latency threshold is automatically canceled, or modified to be expired, from the data transaction processing system memory, so that the data transaction processing system does not perform the transaction requested in the electronic data transaction request message, reducing the processing cycles performed by the data transaction processing system and its memory footprint.

Abstract: The disclosed embodiments relate to implementation of a trading system or trading system architecture having multiple transaction processors that process or execute instructions. The instructions are sent to the transaction processors before they are to be executed, so that when an instruction identifier corresponding to a pre-sent or pre-loaded instruction is sent to a transaction processor, the transaction processor can retrieve and execute the corresponding instruction without unnecessary delay, thus reducing transaction processing latency and improving computing efficiency.

Abstract: The disclosed embodiments relate to implementation of a trading system or trading system architecture having multiple transaction processors that execute financial transactions as well as scheduled tasks. The multiple transaction processors perform all actions independently of each other, but can be configured to execute the financial transactions or scheduled tasks in a controlled, coordinated, and/or synchronized manner based on time signal data augmented to the financial transactions or scheduled tasks by a transaction receiver/orderer.

Abstract: The disclosed embodiments relate generally to efficient data transmission and receipt. Specifically, the disclosed embodiments provide systems and methods for selectively combining multiple, disparate message types and transmitting same via one data feed. A consolidation system determines whether data resulting from an event can be combined or merged based on pre-determined message characteristics and state or environment information, or should be sent via two separate feeds. The merged message may be backwards-compatible so that data recipient computing systems can easily and selectively decide which portion of the merged data is relevant to the data recipient computing system, only read the relevant portions. Thus, multiple data receivers, which typically consume different message types, can receive and consume the same merged or consolidated message.

Abstract: The disclosed embodiments relate to systems and methods for matching orders for a financial product. A first order for a financial product is received. The first order includes a preference for a first order book. An order processer selects a first hardware match processor based on the preference. A first hardware match processor attempts to match the first order with a previously received order in the first order book. A second order for the financial product is received. The second order includes a preference for a second order book. The order processor selects a second hardware match processor based on the preference. A second hardware match processor attempts to match the second order with a previously received order in the second order book. The first and second hardware match processors use different matching algorithms.

Abstract: A method for generating a prediction of a latency of a transaction processing system includes: sampling a first plurality of messages from a database that stores data indicative of messages previously processed by the transaction processing system including a characteristic and a processing time of each previously processed message; generating latency tables based upon the characteristics and the processing times of the sampled first plurality of messages; determining a characteristic of each of a second plurality of messages being processed by the transaction processing system; selecting, for each of the second plurality of messages, a latency table from the plurality of latency tables based upon the respective determined characteristic; simulating a processing time for each of the second plurality of messages based upon the respective selected latency table; and generating a latency prediction for the transaction processing system based upon the simulated processing times for the second plurality of message
