Abstract: The disclosed embodiments relate generally to efficient data encoding and transmission. An encoding system determines an encoding interval at which to encode different groups of related data in a data structure. The encoding interval for each group encoded together optimizes the amount of newly received information that is encoded and transmitted in a continuous, repeating loop.

Abstract: The disclosed embodiments relate to ensuring that a selected value, selected, for example, via interaction with a graphic user interface, of a dynamically changing parameter, such as a price, is used when generating an electronic data transaction request message in a data transaction processing system, such as an electronic trading system. The data transaction processing system being a system in which data items, such as financial contracts, e.g., futures contracts, are transacted or otherwise traded by a hardware matching processor that attempts to match electronic data transaction request messages with electronic data transaction request messages counter thereto for the same one of the data items based on multiple transaction parameters. A selected value is temporarily buffered allowing the represented value to update wherein a subsequently generated transaction may be based on the buffered value rather than an updated value.

Abstract: The disclosed embodiments relate to a system for trading using a central counterparty which allows market participants to minimize risk and/or transactional fees associated with a portfolio of bilateral positions without substantially altering a risk profile thereof. In particular, the disclosed embodiments allow a market participant holding a portfolio of heterogeneous bilateral positions, such as positions in interest rate swap (“IRS”) contracts, to net together similar but not identical positions within their portfolio, thereby reducing margin requirements and/or transaction fees, according to criteria specified by the market participant, and which may be different from criteria specified by other market participants, wherein the overall risk exposure desired by the market participant in entering into the positions remains substantially unchanged as does the desired overall risk exposure of the counterparty market participants to those positions.

Abstract: Computer implemented systems and methods are disclosed that allow for the efficient and rapid determination of guarantee funds for clearing member firms. Disclosed systems and methods account for the exposure of self-referencing risk.

Abstract: An electronic tokening system implemented by a data source transmits secure electronic tokens including time-based values to a plurality of terminals. The terminals may be geographically disparate, and the different terminals may have different connection speeds to the data source. The terminals may use the secure electronic tokens to consistently and reliable calculate data values.

Abstract: Methods, devices, and systems for facilitation of communication between participants of an electronic marketplace involve receiving a message generated from a market participant and transmitting the message to other market participants. The facilitation also involves receiving responses to the message from the other market participants and transmitting the responses to the message originating market participant such that the transmitted response is imperceptible to the other market participants.

Abstract: A computer implemented method and system for a selectively replicated trustless persistent store is provided using a bilateral distributed ledger. The selectively replicated trustless persistent store synchronizes current state data stores shared among multiple parties. Data modifications may be made in any shared store locally and then are automatically replicated across other permissioned stores. The selectively replicated trustless persistent store is responsible for getting the data validated and agreed upon before committing locally.

Abstract: The disclosed embodiments relate to automated enablement of deferred physical delivery of an asset, for which physical delivery is called for in a bilateral contract, by automatically settling the bilateral contract among the parties thereto with positions in specifically tailored futures contracts with a defined later delivery date and, based thereon, extinguishing the bilateral contract requirement for physical delivery. This electronic substitution of equivalent futures positions for both parties in place of the physical delivery requirement, the delivery and payment obligations are bifurcated enabling either party to continue, unpenalized, with their respective obligation irrespective of the other party's actions, enabling the resultant positions available for offsetting/netting, so as to readily exit a position or utilize it to reduce monetary requirements, e.g.

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: A computer implemented method determines a margin requirement for a financial product portfolio. Market conditions for the financial product portfolio are characterized by a zero curve. The method includes producing a plurality of scenario curves, each scenario curve reflecting a principal component analysis (PCA) model of the zero curve with a respective PCA factor of a plurality of PCA factors of the PCA model offset from a corresponding base value for the zero curve, calculating a respective projected value of the financial product portfolio for each scenario curve of the plurality of scenario curves, calculating a loss risk amount for each PCA factor based on the respective projected value and a current value of the financial product portfolio, and determining the margin requirement based on a sum of the loss risk amounts for the plurality of PCA factors.

Abstract: Systems and methods are provided to identify abnormal transaction activity by a participant that is inconsistent with current conditions. Historical participant and external data are identified. A recurrent neural network identifies patterns in the historical participant and external data. A new transaction by the participant is received. The new transaction is compared using the patterns to the historical participant and external data. An abnormality score is generated. An alert is generated if the abnormality score exceeds a threshold.

A report is generated that describes at least one transaction in response to the proposed edge associated with the first vertex of the series and the second vertex of the series for the at least one of the participants.
