The verification application utilizes “typed-data” (i.e., data having known types that are associated with the data itself, e.g., XML-based data) such that a number of parameters can be set for each event and a number of result parameters can be checked for each result in at least one script. A series of scripts can be combined into an action file that may invoke scripts and override parameters within the invoked scripts. The events can be sent and received using a number of messaging protocols and communications adapters. | 08-21-2014 |
20150039489 | Electronic Trading Platform and Method Thereof - A computerized trading system having a plurality of independent trading environments for trading quotes relating to financial instruments received from quoting firms. A multicast data bus provides communication between a matching engine, a plurality of edge applications operating in each independent trading environment, and an order gateway which is common to the plurality of independent trading environments. Quotes are received from the quoting firms at the respective quote interface applications. The quotes are placed in the respective assigned areas of the shared memory. The matching engine matches the received quotes by polling and processing each area of the shared memory. The matching engine, upon completion of polling all areas of the shared memory, checks a port of the multicast data bus to receive messages transmitted by the edge applications and to receive incoming orders for financial instruments from the order gateway. | 02-05-2015 |
