Simplified Messages Based on MTF Post Trade Event Sequence Paper
Introduction • Illustrates what generic messages would look like • Includes solution to • Acknowledgements • Exceptions • Parties and accounts • Still open questions regarding • Use of choices to select events • RFQ, Matching processes • Naming of messages
Extensions • Have used a choice group for content rather than a substitution group for now • Need an approach that tackles both extending existing message and creating new ones • Not easy with the limitations of schema
requestQuote • Document suggests trade or post trade event as payload but current message is based on loosely defined products not trades • Position of ‘documentation’ element is problematic for complex derivatives (e.g. CDS)
quoteException • Error expressed in terms of numeric codes, XPaths and text values • Could add Exception.model content to ExceptionMessage and use same type for all messages
quote • Document suggests trade or post trade event as payload but current message is based on loosely defined products not trades
quoteCancelled & quoteUpdated • No quoteCancelled in current messaging • Quotation always have an expiration date/time and can’t be retracted by the offerer • ‘dictum meum pactum’ • Requesters don’t have to take up offers (might have got a better one) • Do quotes need updating? • Probably not necessary, requester can just ask for another
placeOrder • Payload is a trade or a trade event
orderAcknowledgement • What content • CorrelationId could be useful to include
orderException • Order can’t be executed for business reasons
executionNotification • Notification to trading party, or advice to a downstream organization. • Payload can be a trade or a post-trade event • Correctable
executionRetracted • How much detail of the action being retracted should be specified?
