Random End (MW)

Random End (MW)

Send a Random End market-data message for a symbol or update its Random End triggering condition (tag 30614).

Random End control is available from Admin UI → Event Control → Send Random End.

Send Random End button in Event Control

The dialog has two tabs:

  • Send MW sends a Random End (35=MW) market-data message for one board.
  • Set Symbol Condition updates tag 30614 for the symbol on every existing board.

Prerequisites

Before sending MW:

  1. The Market, Board, and 12-character Symbol must exist in the simulator.
  2. Tag 30614 for the selected symbol and board must be 1 or 2.
  3. The deployment must contain an ${MarketID}-MW entry in MDDSMsgTypeConfig.

If tag 30614 is 0, set it from the Set Symbol Condition tab first.

Send MW

The Send MW tab is active by default whenever the dialog opens.

Select Send MW after reviewing the values. The simulator publishes MW to the configured MDDS topic for the selected market.

Sending MW does not change the simulator's trading-session state.

Set Symbol Condition

Random End Set Symbol Condition tab

This tab updates the Random End triggering condition (30614) for the selected Market and Symbol.

ValueMeaningMW availability
0Not triggeredMW is rejected
1Unconditional triggerMW is allowed
2Conditional triggerMW is allowed

The update applies to every existing board of the symbol. After a successful update, the simulator persists the new value and publishes a separate Security Definition (35=d) message for each updated board.

Board is intentionally not part of this form because the update is symbol-wide.
