- About Trading Session
- Prior to February 10, 2011, Trading session consists of the night session, the morning session, and the afternoon session.
- Morning session data for this period is not recorded, and afternoon session data is recorded as day session data. (Note that the whole day data reflects all sessions.)
- After February 14, 2011, Trading session consists of the night session and the day session.
- About key items in response
- When emergency margin is triggered, data as of both the clearing price calculation and the emergency margin calculation are generated for the same trading day and issue. Therefore, it is possible to uniquely identify the record by combining Date, Code and EmMrgnTrgDiv (EmergencyMarginTriggerDivision).
