For any asset, you can set a volume change-triggered alarm that goes off when the volume for the selected asset rises by the amount you define. The Volume field and page title turn red and start to blink when the volume has increased by your set amount. You can also set an audio alarm that notifies you by beeping.
Each line of market data with an attached alarm will always take up one live market data line whether the page is open (active) or closed. You can only receive market data for a limited number of live market data lines (usually 40).
When you log off,. any alarms you have set will be shut off unless you choose to preserve them between sessions. To do this, select Preserve the alarm between sessions when you set the alarm.
