Database Server: ORACLE, TimesTen
Operating System Unix/ Red hat Linux
FX Execution Manager (FXE) is one of the main components of M-DAQ systems. Main function is to
receive securities order acknowledgement from Order Manager (OM) and send FX orders to LPs.
LPs can monitor their position or FX exposure by the pre-configured Rule-based Automated
Threshold System (RATS). RATS manages its high number of FX trade tickets with aggregation
function and helps to maximize the netting benefit. LPs can configure the automated threshold via
GUI based tool.
Since FXE should handle a minimum of 200 FX Transactions per second , this module is coded with
Real time multi threads and No heap real time threads . This module also uses the scoped
memory area to avoid the unpredictable behavior of the Java Garbage Collector.
M-DAQ Rule-Based Automated Threshold System (RATS) is employed to offer monitoring
solutions for the Liquidity Providers in checking their FX Exposure.
Through RATS, various logics could be implemented for easy tracking of transactions and allow
transparency. A Graphical User Interface (GUI) will be provided to the Liquidity Providers for their
easy monitoring and setting threshold.
