Abstract: A computer trading system includes a quote screening function configured to accept quotes specifying a quote amount in a price where the quote amount is greater than a minimum quote amount to produce screen quote messages and to reject quotes specifying a quote amount less than the minimum quote amount. A market view generator generates market views from those quotes which specify an amount greater than or equal to the minimum quote amount. An order screening function only accepts orders specifying an amount less than a maximum transaction amount submitted in response to the market views to produce screened order messages. A transaction processor receives screened quote messages and screened order messages and matches appropriate messages with each other. The minimum quote amount is substantially equal to or greater than the maximum transaction amount whereby a screened order message can be matched entirely with one screened quote message.

Abstract: A trading system such as an anonymous trading system for trading financial and other instruments can vocalize trading data to trader workstations as well as display it on a screen. Where a trader selects to receive vocal announcements, a trading floor identifier unique to his trading floor is also announced at random intervals.

Abstract: Quotes entered into an automated trading system may comprise a visible, or primary, amount, and a linked or hidden amount. The visible amount only is shown to other traders on the system but part or all of the linked amount may be dealt if the order with the quote is match is for an amount greater than the visible amount. If, after matching and deal confirmation, all the visible amount has been dealt, but some or all of the linked amount remains, a fresh order for the remaining linked amount is generated and submitted to the trading system for matching. The new quoted may be visible only or may have a visible component up to a limit specified by the maker on submission of the original quote, with the remainder being linked. Maker quotes converted to taker quotes by an auto-match routine may be resubmitted for undealt linked amounts in the same way. In one aspect of the invention, linked amounts are matched and dealt before visible amounts.

Abstract: This invention resides in receiving a price feed of data specifying prices of instruments to be traded and converting prices to quotes which specify a price at which a trade can be made and an amount for that trade. In particular, the invention resides in a quote submission interface that controls whether quotes should be derived and submitted from a price feed. In an embodiment of the invention, the quote submission interface determines whether quotes should be submitted based upon a variety of factors, including any combination of the frequency of price changes, the price level in comparison to a best price, the format of price messages, the net exposure as a result of automatic deal submission, and other factors.
