Trenton,
I don't know about a loud beep but, someone on this thread posted a link that will send an alert via text message to your cell phone. This will get you away from the screen but not the action. It works pretty good and you can set your own parameters. The link is
alert!fx™ - foreign exchange (forex) alerts. and it's free. Also look back in this thread fro additional info. This should allow some toe time. Just a suggestion.
