Random End (MW)
Send Random End messages, update an ISIN triggering condition, or end Random End with an unconditional trigger.
Random End control is available from Admin UI → Event Control → Send Random End.
The dialog has three tabs:
- Set ISIN Condition updates tag
30614on every existing board for the ISIN. - Unconditional Trigger ends Random End for one ISIN or every eligible ISIN.
- Send MW sends a Random End (
35=MW) market-data message.
ISIN input rules
Every ISIN field in Event Control uses the same validation:
- Enter
*to target everything supported by the selected action. - Or enter exactly 12 characters in the form
AA0000000000: two leading letters, nine alphanumeric characters, and one trailing digit. - Lowercase letters are automatically converted to uppercase.
Set ISIN Condition
This tab updates the Random End triggering condition (30614) for the selected Market and ISIN.
| Value | Random End condition |
|---|---|
0 | Not triggered |
1 | Unconditional trigger |
2 | Conditional trigger |
The update applies to every existing board for the ISIN. Enter * to update every ISIN in the selected Market.
Unconditional Trigger
The Unconditional Trigger tab ends Random End:
- Select Market.
- Enter one ISIN to target that ISIN.
- Enter
*to target every eligible ISIN in the selected Market.
An ISIN is triggered only when tag 30614 has armed Random End, its current session is a call auction, and its estimated auction volume is greater than 0. Eligible ISINs move to the appropriate next session, and the result shows the number of triggered ISINs.
