Embodiments of the present invention provide a novel system and method for TCP-to-multicast (T2M) communications. The T2M techniques may allow a client to make a single TCP connection that then fans out into communications with multiple back-end resources. Such one-to-many communications may be invisible to the client but can achieve many practical benefits.

System and method for TCP-to-multicast (T2M) communications and related network architecture

Embodiments of the transmission latency leveling apparatuses, methods and systems provide an electronic bidding order management infrastructure, such as a 'point-of-presence,' which receives and routes electronic trading orders from different trading entities at a server via a transmission medium to create a certain amount of transmission latency before the trading orders could arrive at and be executed at electronic exchanges to reduce latency arbitrage and/or order book arbitrage that may be experienced by high frequency trading participants. A similar transmission latency may be applied to the egress transmission of market data updates issued by an electronic exchange. Other techniques for facilitating electronic trading are also disclosed.

Transmission latency leveling apparatuses, methods and systems

In order to protect a trading party from predatory trading strategies employed by some market participants, especially during certain periods when quotes for a particular security are experiencing rapid changes or transitions, embodiments of the present invention facilitate and support a new type of trading orders whose booking and execution behaviors are dynamically varied in response to environmental market conditions. Pursuant to predefined rules for the new type of trading orders, the orders may be allowed to trade at more aggressive price levels if the market is relatively stable, and the orders can only trade at less aggressive price levels when the market is unstable.

Dynamic peg orders in an electronic trading system

Embodiments of the present invention may provide an improved distributed computing system. Entities in the distributed computing system may be divided into four categories: writers, readers, gateways, and applications. End users may interact with the system via the applications through the gateways. The role of writers and readers may be separated to distribute computational burdens. Writers may generate messages for an event stream. The messages may include a timestamp for consistent global ordering. The readers may arrange messages from various writers based on the timestamps to generate globally time-consistent event streams.

System and method for creating time-accurate event streams

A specialized memory structure is provided for storing parts of orders received at an electronic trading system. A received order is divided into a displayed portion and a non-displayed portion, and each portion is allocated to a respective part of the memory structure. The memory structure is configured such that while matching the order with a contra order, priority is given to the displayed portion over the non-displayed portion. If such a match occurs, the displayed portion may be replenished. The matching in the non-displayed portion generally occurs according to rules of applying discretion. The matching in the displayed portion may occur at the displayed price or according to the rules of discretion.

Systems and methods for processing full or partially displayed dynamic peg orders in an electronic trading system

In a system for executing transaction requests, a received request for a transaction in an item is delayed prior to matching that request with another request for transaction in that item by a delay based on a communication delay and/or a processing delay. The communication delay represents the time required to receive updated information about the item and the processing delay represents the time required to compute an updated item price using the received updated information.
