Velocity Alert Volume?

New trader here, just set up Apex on NT and the volume on the Velocity Alert is too high. How can I adjust the sound volume or turn it off?

The volume can’t be changed through NT. Disable by setting PlayAudioAlert = False

okay, found it thanks.

You can mute it but not change the volume level. If you just want to mute the alert right click on chart go to indicators - click on velocity then set audible alerts to off/false
