Manage Intraday Opening Hours Information
The Charting blade obtains information regarding opening hours and timezones from the IDN feed. This information can be rerequested regularly, and opening hours for specific objects and exchanges can be defined.
A note on time format
Trading hours information can take various forms:
DD-DD HHMM-HHMM
or
DD HHMM-HHMM DD HHMM-HHMM …
Example:
MO-FR 0800-1630
This is the same as:
MO 0800-1630 TU 0800-1630 WE 0800-1630 ...
You can also define partial sessions during the day in the form:
DD HHMM-HHMM,HHMM-HHMM…
For example:
MO 0930-1200,1330-1600
