ASPEN_InstrumentUpdateNotice

Purpose

Inform the application of changes in the master record of a financial instrument being watched.

Notice

For this event notice, the notice parameter of the AspenEvent() function receives a pointer to an ASPEN_INSTRUMENT_UPDATE_NOTICE structure.

This structure is dynamically allocated by Aspen and must be freed using the AspenFreeMemory() function after use.

Structure

typedef struct

{

   ASPEN_INUM inum;

   ASPEN_INSTRUMENT  instrument;

}ASPEN_INSTRUMENT_UPDATE_NOTICE;

Remarks

If the application has requested real-time updates on particular financial instruments, those updates will be reported using ASPEN_InstrumentUpdateNotice events.

Instrument updates reflect real-time changes in instrument prices and/or other fields. Real-time updates for a particular instrument must be enabled by making an ASPEN_GetInstrumentInfo service request. Updates may be disabled using the ASPEN_StopInstrumentUpdates service.
