Alert block
STILL IN DEVELOPMENT
The Alert block allows you to add a message to the Audit Trail and play a sound when certain conditions occur. An alert can be triggered in one of two ways:
- When it receives a TRUE value through its Boolean input port
- When it receives a message through is discrete event message port
Example The Alert block is configured to play a sound and send a message to the Audit Trail when the Formula block sends a TRUE value to the Alert block's Boolean input port, indicating that the trader's P&L is withing ten percent of the maximum allowed.
When an algorithm is executed from the ADL Designer canvas in client-side simulation, an Alert block will not generate an actual audit trail message. Instead, the Alert block will generate the specified text in the Alert Tab of the Information Panel. However, if Sound is selected as the method of alert, the Alert block will generate the specified sound.
