    • A system for managing trading orders comprises a memory operable to store a trade credit associated with a trader. The system further comprises a processor operable to receive a trading order from the trader and determine the trade credit associated with the trader. If the received trading order is a passive trading order, the processor is further operable to increase the trade credit and submit the received trading order for execution. If the received trading order is an aggressive trading order, the processor is further operable to calculate a decrease of the trade credit. If subtracting the calculated decrease from the trade credit would not cause the trade credit to be less than a configurable threshold, the processor is further operable to submit the received trading order for execution and subtract the calculated decrease from the trade credit. If subtracting the calculated decrease from the trade credit would cause the trade credit to be less than the configurable threshold, the processor is further operable to prevent the execution of the received trading order.
    • 用于管理交易订单的系统包括可操作以存储与交易者相关联的交易信用的存储器。 该系统还包括处理器,其可操作以从交易者接收交易订单并确定与交易者相关联的交易信用。 如果接收到的交易订单是被动交易订单,则处理器可进一步操作以增加交易信用并提交所接收的交易订单以供执行。 如果收到的交易订单是一个积极的交易订单,处理器可以进一步操作来计算交易信贷的减少。 如果从贸易信贷中减去所计算的减少量不会导致贸易信贷小于可配置的阈值,则处理器可进一步操作以提交所接收的交易订单以便执行,并从所述贸易信用中减去所计算的减少量。 如果从贸易信用减去计算的减少量将导致贸易信用额小于可配置的阈值,则处理器进一步可操作以防止执行所接收的交易订单。

    • According to one embodiment, a method of managing trading is provided. A first offer for a particular instrument in a particular market is received from a first market maker at a first offer price. A first bid for the same particular instrument in the same particular market is received from a second market maker at a first bid price, the first bid price being higher than or equal to the first offer price. As a result of the first bid price being higher than or equal to the first offer price, the first offer price is automatically increased to a price higher than the first bid price such that a trade is not executed between the first offer and the first bid. In some embodiments, such method may be used to protect market makers from unwanted trades caused by inherent latency in the market makers' pricing engines and/or networks.
    • 根据一个实施例,提供了管理交易的方法。 特定市场上的特定仪器的首次报价以第一个报价价格从第一个制造商收到。 在同一特定市场中对同一特定工具的首次投标以第一投标价格从第二个制造商处收到,第一个投标价格高于或等于第一个报价。 由于第一个投标价格高于或等于首次报价,第一个报价价格自动增加到高于第一个投标价格的价格,使得第一个报价和第一个投标之间没有执行交易 。 在一些实施例中,这种方法可以用于保护制造商免受由市场制造商的定价引擎和/或网络中的固有延迟引起的不必要的交易。
