Systems and methods for communication of financial messages from an Exchange to market participants whereby messages directed to particular market participants may be consolidated with other messages directed to all market participants and communicated via the same communications medium while preserving the anonymity of those market participants to which messages are particularly directed. Accordingly, redundant communications are eliminated, reducing the overall volume of communicated data and the resources necessary in support thereof; inhibition of any one market participant intentionally or unintentionally influencing the market via exposure of their activities, or otherwise unfairly impinging on the exposed activities of other market participants, is maintained; and inequitable information access is eliminated as the consolidated messages are transmitted to all market participants substantially simultaneously over the same medium thereby minimizing or eliminating any advantage or opportunity one market participant may have to receive market information ahead of the other market participants.

Secure consolidated exchange feed for order entry and market data

The disclosed embodiments relate to implementation of a trading system, which may also be referred to as a trading system architecture, having improved performance which further assures transactional determinism under increasing processing transaction loads while providing improved trading opportunities, fault tolerance, low latency processing, high volume capacity, risk mitigation and market protections with minimal impact, as well as improved and equitable access to information and opportunities.

Transactionally deterministic high speed financial exchange having improved, efficiency, communication, customization, performance, access, trading opportunities, credit controls, and fault tolerance

An item is determined to exist in a dataset by arranging the dataset into a plurality of subsets, each bounded by the minimum amount of memory that may be transferred between levels of memory in a memory configuration. The item and the subsets have attributes that allow for a determination of which subset the item would exist in if the item were in the dataset. A singular subset is transferred between levels of memory to determine whether the item exists in the transferred subset. If the item does not exist in the transferred subset, it is determined that the item does not exist in the dataset.
